In warm climates, those having less than two weeks of frosty nights per year, there is no cost impact. The basic requirement for passive solar heating is that the solar collectors must face the prevailing sunlight (south in the Northern Hemisphere, north in the Southern Hemisphere), and the building must incorporate thermal mass to keep it warm in the night. A recent, somewhat experimental solar heating system "Annualized geo solar heating" is practical even in regions that get little or no sunlight in winter.Stephens, Don.

Solar heating has the ability to erode a CAD event by heating the surface in the absence of a thick overcast. However, even a shallow stratus layer during the cold season can render solar heating ineffective. During breaks of overcast for the warm season, absorption of solar radiation at the surface warms the cold dome, once again lowering the Richardson number and promoting mixing.

If the Earth were tidally locked to the Sun, solar heating would cause winds across the mid-latitudes to blow in a poleward direction, away from the subtropical ridge. However, the Coriolis effect caused by the rotation of Earth tends to deflect poleward winds eastward from north (to the right) in the Northern Hemisphere and eastward from south (to the left) in the Southern Hemisphere.Nathan Gasser (2000-08-10).

In 1920s, the idea of solar heating started in Europe. In Germany, housing projects were designed to take advantage of the sun. The research and accumulated experience with solar design then spread across the Atlantic by architects like Walter Gropius and Marcel Breuer. Besides from these early examples, the heating of homes with the sun made slow progress until the 1930s, when several different American architects started to explore the potential of solar heating. The pioneering work of these American architects, the influence of the immigrant Europeans, and the memory of the wartime fuel shortages made solar heating very popular during the initial housing boom at the end of World War II. Later in 1970s, before and after the international oil crisis of 1973, some European architectural periodicals were critical of standard construction methods and the architecture of the time.

Solar heating, cooling, and ventilation technologies can be used to offset a portion of this energy. The most popular solar heating technology for heating buildings is the building integrated transpired solar air collection system which connects to the building's HVAC equipment. According to Solar Energy Industries Association over 500,000 m2 (5,000,000 square feet) of these panels are in operation in North America as of 2015. In Europe, since the mid-1990s about 125 large solar-thermal district heating plants have been constructed, each with over 500 m2 (5400 ft2) of solar collectors.

Tides have also been observed with periods of 8 and 6 hours, although these latter tides generally have smaller amplitudes. This set of periods occurs because the solar heating of the atmosphere occurs in an approximate square wave profile and so is rich in harmonics. When this pattern is decomposed into separate frequency components using a Fourier transform, as well as the mean and daily (24-hr) variation, significant oscillations with periods of 12, 8 and 6 hrs are produced. Tides generated by the gravitational effect of the sun are very much smaller than those generated by solar heating.

It has since been determined that the greater flux at shorter wavelengths was due to the combined flux from Io's volcanoes and solar heating, whereas solar heating provides a much greater fraction of the flux at longer wavelengths. A sharp increase in Io's thermal emission at 5 μm was observed on February 20, 1978 by Witteborn, et al. The group considered volcanic activity at the time, in which case the data was fit into a region on Io in size at . However, the authors considered that hypothesis unlikely, and instead focused on emission from Io's interaction with Jupiter's magnetosphere.

Soil solarization is a hydrothermal process of disinfecting the soil of pests, accomplished by solar power (referred to as solar heating of the soil in early publications) and is relatively a new soil disinfestation method, first described in extensive scientific detail by Katan in 1976. The mode of action for soil solarization is complex and involves the use of heat as a lethal agent for soil pests from the use of transparent polyethylene tarps. To increase the effectiveness of solar heating requires optimal seasonal temperatures, mulching during high temperatures and solar irradiation, and moisture soil conditions. Soil temperatures are lower when decreasing in soil depth and it is necessary to continue the mulching process to control for pathogens.

Passive Solar Heating Diagram The ability to passively heat a building is beneficial during the colder winter months to help keep temperature levels up. Passive solar systems collect and distribute energy from the sun without the use of mechanical equipment such as fans or pumps. Passive solar heating consists of equator-facing glazing (south-facing in the northern hemisphere) to collect solar energy and thermal mass to store the heat. A direct-gain system allows short-wave radiation from the sun to enter a room through the window, where the floor and wall surfaces then act as thermal mass to absorb the heat, and the long-wave radiation is trapped inside due to the greenhouse effect.

When the building was expanded in 1962, the solar collector was abandoned in favor of a conventional boiler system, though the equipment was left intact for possible future use. This decision paid off just a few years later, when the 1973 oil crisis caused a renewed interest in solar energy and brought fresh attention to the Solar Building. In early 1974, Penn State researcher Stanley Gilman received a National Science Foundation grant to restore the building's solar heating system and operate it as part of a multi- year field study intended to identify optimal design criteria for such systems. Following the conclusion of the project, the solar heating system remained in use.

Solar heating system featuring a thermosiphon Thermosiphons are used in some liquid-based solar heating systems to heat a liquid such as water. The water is heated passively by solar energy and relies on heat energy being transferred from the sun to a solar collector. The heat from the collector can be transferred to water in two ways: directly where water circulates through the collector, or indirectly where an anti-freeze solution carries the heat from the collector and transfers it to water in the tank via a heat exchanger. Convection allows for the movement of the heated liquid out of the solar collector to be replaced by colder liquid which is in turn heated.

The firm of Bridgers & Paxton Consulting Engineers was founded in 1951 by Frank Bridgers (1922–2005) and Donald Paxton (1912–2007), both of whom were interested in the potential applications of solar energy. Initially operating out of a garage behind Bridgers' house, the two men conceived a new office building for their firm which would include an experimental solar heating system. They believed such a system would not only save money, but would also allow them to collect valuable data for future projects. In 1954, they were able to put some of their ideas into practice with an innovative heating and cooling system for the Simms Building, which took advantage of the building's south-facing glass curtain wall to provide solar heating in winter.

They are believed to form from the removal of subsurface material, maybe interstitial ice by sublimation (change from solid to a gas). More gentle slopes face in the direction of the equator, while steep scarps face the pole. This is probably due to differences in solar heating. The process is believed to be ongoing.

A simple picture also assumes a steady state, but in the real world, the diurnal cycle as well as the seasonal cycle and weather disturbances complicate matters. Solar heating applies only during daytime. During the night, the atmosphere cools somewhat, but not greatly, because its emissivity is low. Diurnal temperature changes decrease with height in the atmosphere.

Solar radiation pressure strongly affects comet tails. Solar heating causes gases to be released from the comet nucleus, which also carry away dust grains. Radiation pressure and solar wind then drive the dust and gases away from the Sun's direction. The gases form a generally straight tail, while slower moving dust particles create a broader, curving tail.

Solar thermal collectors and collector systems with flat or evacuated tube collectors find numerous applications in the practice. These include process water and solar heating systems, cooling and ventilation systems and sea water desalination systems. Also façade-integrated collectors are implemented. With linear concentrating collectors, operating temperatures from 150 °C to over 400 °C are achieved.

The Coriolis force is caused by the planet's rotation on its axis. On other planets, internal heat rather than solar heating drives their jet streams. The Polar jet stream forms near the interface of the Polar and Ferrel circulation cells; the subtropical jet forms near the boundary of the Ferrel and Hadley circulation cells. Other jet streams also exist.

In deserts, lack of ground and plant moisture that would normally provide evaporative cooling can lead to intense, rapid solar heating of the lower layers of air. The hot air is less dense than surrounding cooler air. This, combined with the rising of the hot air, results in a low- pressure area called a thermal low.Glossary of Meteorology (2009).

During the summer increased solar heating of the surface water leads to more stable density stratification, reducing the penetration of wind- driven mixing. Because seawater is most dense just before it freezes, wintertime cooling over the ocean always reduces stable stratification, allowing a deeper penetration of wind-driven turbulence but also generating turbulence that can penetrate to great depths.

Meteorite findings occur only on a minority of all blue-ice areas and are mostly limited to inland blue-ice areas whereas coastal ones tend to be lacking in meteorites. This might reflect the fact that at low altitude the ice surrounding the meteorites can melt due to solar heating of the meteorite, thus removing it from view.

Solar heating and tidal oscillations in the lower ionosphere move plasma up and across the magnetic field lines. This sets up a sheet of electric current in the E region which, with the horizontal magnetic field, forces ionization up into the F layer, concentrating at ± 20 degrees from the magnetic equator. This phenomenon is known as the equatorial fountain.

|
It is also possible that solar heating caused sublimation of ice, perhaps beneath the surface in a "pocket," and the force of the ejection of material (after being exposed to solar heating during the rotation of the asteroid) resulted in the spin rate increase. A prior example of such an occurrence is in the literature. In April 2019, upon analyzing archive images taken in 2013, 2016 and 2017, it was found that Gault had been perpetually active for at least five years before the discovery, with a tail visible when the asteroid was near its furthest distance from the Sun during the 2013 apparition. If its activity is indeed caused by a rotational breakup, then Gault has remained active far longer than any other object of this type seen before.

Glauber's salt, the decahydrate, is used as a laxative. It is effective for the removal of certain drugs such as paracetamol (acetaminophen) from the body, for example, after an overdose. In 1953, sodium sulfate was proposed for heat storage in passive solar heating systems. This takes advantage of its unusual solubility properties, and the high heat of crystallisation (78.2 kJ/mol).

His charts were an important contribution to the emerging field of information visualisation.

The technology behind solar power generation varies, depending on the method being used to generate power. Photovoltaic (PV), concentrating solar power (CSP), and solar heating and cooling (SHC) systems are the three different solar technologies used to generate power. Photovoltaic cells convert sunlight into power directly. Observed on solar panels, photovoltaic is the more familiar method of technology in regards to solar power.
|
|
Solar energy is produced in three different ways as mentioned above: via photovoltaic cells (PV), concentrating solar power (CSP), and solar heating and cooling (SHC). In the case of photovoltaic cells, electricity is generated via the absorption of sunlight. The sunlight is converted into electricity by a semi-conductor. The photons, after phasing through the semi-conductor, loses their electrons.

A third bedroom and two additional bathrooms are on other levels. The house is in height. Although local zoning codes do not normally allow homes of this height, the lowest two floors are considered basement levels, three floors are livable space, and the remainder is a natural convective cooling and passive solar heating system. A hydraulic elevator provides access to the main level on the sixth floor from the ground level.

One of the most effective erosion mechanisms is the import of colder air—also known as cold air advection—aloft. With cold advection maximized above the inversion layer, cooling aloft can weaken in the inversion layer, which allows for mixing and the demise of CAD. The Richardson number is reduced by the weakening inversion layer. Cold advection favors subsidence and drying, which supports solar heating beneath the inversion.
|

It is theorized that, due to the atmospheric mixing that results, the air temperature perturbation within the UHI is generally minimal or nonexistent during the day, though the surface temperatures can reach extremely high levels. At night, the situation reverses. The absence of solar heating leads to the decrease of atmospheric convection and the stabilization of urban boundary layer. If enough stabilization occurs, an inversion layer is formed.

Eggs require warmth, and some nests are insulated by the owners' feathers, others from ones found elsewhere. External temperatures dictate how the eggs are incubated. The snowy owl has to do so itself, because of its habitat; however, the maleo is able to take advantage of solar heating. The amount of eggs laid also varies: for example, the kiwi lays just one, whereas the blue tit will deposit many.

The first is used as an extension of the exhibition space and for temporary exhibits, the second an event space and the third a workshop space. The museum design employs passive solar heating and natural cooling and lighting. The museum, also supported by NSW Regional Cultural Fund, was visited by New South Wales premier Gladys Berejiklian and minister Troy Grant on 2 July 2018. Gulgong Holtermann Museum officially opened on 26 October 2019.

The black painted wall is constructed of approximately 2 feet thick concrete with an air space and a double glazing on its exterior side. The house is primarily heated by radiation and convection from the inner surface of the concrete wall and the results from studies show that 70% of this building’s yearly heating needs are supplied by solar energy. Therefore, the efficiency of the system is comparable to a good active solar heating system.

To understand Mars' ancient climate, and whether it might have created environments habitable for life, first we need to understand Mars' climate today. Each mission to Mars has made new advances in understanding its climate. Mars has seasonal variations in the abundances of water vapor, water ice clouds and hazes, and atmospheric dust. During southern summer, when Mars is closest to the Sun (at perihelion), solar heating can raise massive dust storms.

The campus is notable for its employment of solar photovoltaic panels, one on a ninety-meter (293') long solar wall, is the longest in the world. Water is heated through the employment of solar heating panels. The campus plan is devised to re-generate the subterranean aquifer system. A water collection pool, near the river, acts as a holding pool, recharging and sustaining the micro-environment and bio-diversity of the campus.

Earth sheltering is often combined with solar heating systems. Most commonly, the utilization of passive solar design techniques is used in earth shelters. In most of the Northern Hemisphere, a south-facing structure with the north, east, and west sides covered with earth is the most effective application for passive solar systems. A large double glazed window, triple glazed, spanning most of the length of the south wall is critical for solar heat gain.

A superinsulated house is intended to reduce heating needs very significantly and may even be heated predominantly by intrinsic heat sources (waste heat generated by appliances and the body heat of the occupants) with very small amounts of backup heat. This has been demonstrated to work even in very cold climates but requires close attention to construction details in addition to the insulation (see IEA Solar Heating & Cooling Implementing Agreement Task 13).

|
Wells's insulation recommendations increase as the depth of the soil decreases (a negative correlation). In addition to thermal mass, Earthships use passive solar heating and cooling. Large front windows with integrated shades, trombe walls and other technologies such as skylights or Steve Baer's "Track Rack" solar trackers are used for heat regulation. Earthships are positioned so that its principal wall, which is nonstructural and made mostly of glass sheets, faces directly towards the equator.

Thus an automated ship can scrape up loose surface materials from, say, the relatively nearby 4660 Nereus (in delta-v terms), process the ore using solar heating and CO, and eventually return with a load of almost pure metal. The economics of this process can potentially allow the material to be extracted at one-twentieth the cost of launching from Earth, but it would require a two-year round trip to return any mined ore.

It's estimated that by 1975 an average American will use 20,000 horsepower-hours of fuel. Solar energy will be a likely solution and research by Dr. Charles Greeley Abbot produced a solar powered engine. The French solar furnace at Mont-Louis is used for high-temperature research of metals. The Indian scientist Dr. S. Bhatnagar experimented with solar ovens for cooking food and Dr. Mária Telkes developed a home that used Solar heating exclusively.

Concentrating solar power (CSP) features turbines powered by huge areas of solar mirrors that in turn derive energy from the sun. Solar heating and cooling (SHC) systems can be installed into homes just like other basic installations. Solar water heating provides that a solar collector store heated water, which is warmed by thermal energy from the sun, in a storage tank. Hot or cold, this water can then be used for any residential purposes.

In some designs, the mass is located 1 to 2 ft (0.6 m) away from the glass, but the space is still not usable. The surface of the thermal mass absorbs the solar radiation that strikes it and stores it for nighttime use. Unlike a direct gain system, the thermal storage wall system provides passive solar heating without excessive window area and glare in interior spaces. However, the ability to take advantage of views and daylighting are eliminated.

For instance, when the ITCZ is situated north of the Equator, the southeast trade wind changes to a southwest wind as it crosses the Equator. The ITCZ is formed by vertical motion largely appearing as convective activity of thunderstorms driven by solar heating, which effectively draw air in; these are the trade winds. The ITCZ is effectively a tracer of the ascending branch of the Hadley cell and is wet. The dry descending branch is the horse latitudes.

Then another passive collector-distributor Trombe Wall system is built in 1970, in Montmedy, France. The house with 280 m³ living space required 7000 kWh for space heating annually. At Montmedy-between 49° and 50° North latitude-5400 kWh were supplied by solar heating and the remainder from an auxiliary electrical system. The annual heating cost for electricity was approximately $225 when compared to an estimated $750 for a home entirely heated by electricity in the same area.

Solar roof ponds are unique solar heating and cooling systems developed by Harold Hay in the 1960s. A basic system consists of a roof-mounted water bladder with a movable insulating cover. This system can control heat exchange between interior and exterior environments by covering and uncovering the bladder between night and day. When heating is a concern the bladder is uncovered during the day allowing sunlight to warm the water bladder and store heat for evening use.

This idea was developed further in the all-solar heating system Bridgers and Paxton designed two years later for their pioneering Solar Building. While the system was efficient, it was not without problems. The fact that spent water from the system was re-deposited in the ground after use meant that additives could not be used without contaminating the groundwater, and corrosion soon became an issue. Eventually, it was converted to a closed system in 1965.

They often had to solve complicated problems and the designers always agreed with their solutions. The TV tower is regularly checked for geodetic compliance: foundation settling, vertical deviation, condition of reinforced concrete and metal components, and other parameters. The allowed sway of the top of the TV tower due to wind is 1.5 metres; of the viewing platform, 90 cm. Besides winds, the tower is affected by solar heating, resulting in the top “drawing” a peculiar curve.

Clearing for agricultural needs and for heat was a necessity for long-term survival in Roman times, though there is a debate as to whether the Romans understood the implications of deforestation. Richard Grove said, "states will act to prevent environmental degradation only when their economic interests are shown to be directly threatened." The Romans did have some forms of ecological conservation though. Recycling of glassware was practiced along with architectural design that utilized solar heating.

The Drake Landing Solar Community in Alberta, Canada, has now achieved a year-round 97% solar heating fraction, a world record made possible only by incorporating STES. The use of both latent heat and sensible heat are also possible with high temperature solar thermal input. Various eutectic mixtures of metals, such as Aluminium and Silicon (AlSi12) offer a high melting point suited to efficient steam generation, while high alumina cement-based materials offer good thermal storage capabilities.

In the United States, as a high-pressure system moves eastward out to the Atlantic, northerly winds are reduced along the southeast coast. If northeasterly winds persist in the southern damming region, net divergence is implied. Near-surface divergence reduces the depth of the cold dome as well as aid the sinking of air, which can reduce cloud cover. The reduction of cloud cover permits solar heating to effectively warm the cold dome from the surface up.

The strong static stability of a CAD inversion layer usually inhibits turbulent mixing, even in the presence of vertical wind shear. However, if the shear strengthens in addition to a weakening of the inversion, the cold dome becomes vulnerable to shear-induced mixing. Unlike solar heating, this CAD event erosion happens from the top down. Mixing occurs when the depth of the northeasterly flow becomes increasingly shallow and strong southerly flow makes a downward progression resulting in high shear.

General circulation of the Earth's atmosphere: The westerlies and trade winds are part of the Earth's atmospheric circulation. In 1494, Christopher Columbus experienced a tropical cyclone, which led to the first written European account of a hurricane.Morison, Samuel Eliot, Admiral of the Ocean Sea: A Life of Cristopher Columbus, Boston, 1942, page 617. In 1686, Edmund Halley presented a systematic study of the trade winds and monsoons and identified solar heating as the cause of atmospheric motions.

Hence, in his view, a needy community got little value from the application of viable technology. Subsequently, Hess and his wife, Therese, moved to rural Opequon Creek between Martinsburg and Kearneysville, West Virginia, where he set up a welding shop as partial support for his household. He became deeply involved with local affairs there. Hess built an affordable house that relied largely on passive- solar heating, and took an interest in wind power and all forms of solar energy.

Hyperboreae Undae dunes shown with surface frost. The dunes become darker when the frost sublimates from solar heating and the dark sands are revealed. Although the dunes surrounding the Martian north pole show no signs of movement, two possible exceptions may be the dunes in parts of Abalos Undae, and the dunes of Hyperboreae Undae. In the case of Hyperboreae Undae, the dunes close to its eastern boundary appear to be buried under the Planum Boreum 3 unit.

Earth's atmosphere and hydrosphere—Earth's heat engine—are coupled processes that constantly even out solar heating imbalances through evaporation of surface water, convection, rainfall, winds and ocean circulation, when distributing heat around the globe. A Hadley cell is an example of a heat engine. It involves the rising of warm and moist air in the earth's equatorial region and the descent of colder air in the subtropics creating a thermally driven direct circulation, with consequent net production of kinetic energy.

Retrieved on 2009-03-02. Thermal lows occur near the Sonoran Desert, on the Mexican plateau, in California's Great Central Valley, the Sahara, over north-west Argentina in South America, over the Kimberley region of north-west Australia, the Iberian peninsula, and the Tibetan plateau. Over land, intense, rapid solar heating of the land surface results in heating of the lowest layers of the atmosphere via reradiated energy in the infrared spectrum. The resulting hotter air is less dense than surrounding cooler air.

An isolated thunderstorm rolls through Wah Wah Valley, Utah. This type of monsoonal pattern is very common in the late summer of the southwest US. In deserts, lack of ground and plant moisture that would normally provide evaporative cooling can lead to intense, rapid solar heating of the lower layers of air. The hot air is less dense than surrounding cooler air. This, combined with the rising of the hot air, results in a low pressure area called a thermal low.

The Willcox Playa is located in the northern region of Sulphur Springs Valley; drainage to the playa from the east is from the connected Dos Cabezas-Chiricahua Mountains; drainage from the southwest is from the Dragoon Mountains, and the Little Dragoon Mountains. During the summer, intense solar heating sometimes gives rise to large dust devils, and strong winds from thunderstorms and winter storms can produce dust storms rising from the dry lake that can hinder traffic on the Interstate 10 highway.

109 Piscium b (aka HD 10697 b) is a long-period extrasolar planet discovered in orbit around 109 Piscium. It is at least 6.38 times the mass of Jupiter and is likely to be a gas giant. As typical for long-period planets discovered around other stars, it has an orbital eccentricity greater than that of Jupiter. The discoverers estimate its effective temperature as 264 K from solar heating, but it could be at least 10-20 K warmer because of internal heating.

First-generation technologies, which are already mature and economically competitive, include biomass, hydroelectricity, geothermal power and heat. Second-generation technologies are market-ready and are being deployed at the present time; they include solar heating, photovoltaics, wind power, solar thermal power stations, and modern forms of bioenergy. Third- generation technologies require continued R&D; efforts in order to make large contributions on a global scale and include advanced biomass gasification, hot-dry-rock geothermal power, and ocean energy.International Energy Agency (2007).

Thermal fracturing in glass occurs when a sufficient temperature differential is created within glass.Technical note no: 65 "Centre For Window and Cladding Technology" As a warmed area expands or a cooled area contracts, stress forces develop, potentially leading to fracture. A temperature differential may be created in many ways, including solar heating, space heating devices, fire, or hot and cold liquids. Sloping glass surfaces are subject to greater solar radiation than vertical surfaces and so are more prone to solar thermal fracture.

The photo shows a training meeting with factory workers in a stainless steel ecodesign company from Rio de Janeiro, Brazil. The first traceable concepts of environmental designs focused primarily on solar heating, which began in Ancient Greece around 500 BCE. At the time, most of Greece had exhausted its supply of wood for fuel, leading architects to design houses that would capture the solar energy of the sun. The Greeks understood that the position of the sun varies throughout the year.

Homes in Aurora will be expected to have an energy efficiency rating of at least 6 stars, achieved by using efficient appliances, solar-heating of water where possible, insulation of buildings and houses designed with good ventilation and orientation of windows. Streets are designed for optimal capturing of solar power. Aurora's water efficiency measures aim to have 54% less potable water consumed per person than normal houses, and are expected to discharge 90% less water into the sea. Water efficient appliances will be used to minimise consumption.

Interior of the swimming pool WIPE's indoor swimming pool, constructed in 1984 and put into service since 1986, is a combination of public and competition pool. The pool is maintained in constant temperature. It was then the largest swimming pool in China equipped with solar heating system, which were able to heat 70 tons of hot water daily according to its original design. Affiliated to and overseen by teaching and researching section of swimming in WIPE, the Swimming pool have been run by a private contractor.

Its design was inspired by the latest trends in modern architecture, especially the Lever House in New York City, with glass curtain walls and a combination of vertical and horizontal volumes. Sandstone blocks from the previous building on the site, the Commercial Club, were included in the exterior walls. The Simms Building also included an innovative radiant heating and cooling system with limited solar heating capabilities. The building received attention nationally as well as locally and helped catalyze the modern architecture movement in New Mexico.

A horizontal temperature gradient exists while moving North-South along a meridian because curvature of the Earth allows for more solar heating at the equator than at the poles. This creates a westerly geostrophic wind pattern to form in the mid-latitudes. Because thermal wind causes an increase in wind velocity with height, the westerly pattern increases in intensity up until the tropopause, creating a strong wind current known as the jet stream. The Northern and Southern Hemispheres exhibit similar jet stream patterns in the mid-latitudes.

Solar energy, radiant light and heat from the sun, is harnessed using a range of ever-evolving technologies such as solar heating, solar photovoltaics, solar thermal electricity, solar architecture and artificial photosynthesis.Solar Fuels and Artificial Photosynthesis. Royal Society of Chemistry 2012 (accessed 11 March 2013) Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert and distribute solar energy. Active solar techniques include the use of photovoltaic panels and solar thermal collectors to harness the energy.

Because greenhouse gas molecules radiate infrared energy in all directions, some of it spreads downward and ultimately returns to the Earth's surface, where it is absorbed. The Earth's surface temperature is thus higher than it would be if it were heated only by direct solar heating. This supplemental heating is the natural greenhouse effect. It is as if the Earth is covered by a blanket that allows high frequency radiation (sunlight) to enter, but slows the rate at which the low frequency infrared radiant energy emitted by the Earth leaves.

A building's location and surroundings play a key role in regulating its temperature and illumination. For example, trees, landscaping, and hills can provide shade and block wind. In cooler climates, designing northern hemisphere buildings with south facing windows and southern hemisphere buildings with north facing windows increases the amount of sun (ultimately heat energy) entering the building, minimizing energy use, by maximizing passive solar heating. Tight building design, including energy-efficient windows, well-sealed doors, and additional thermal insulation of walls, basement slabs, and foundations can reduce heat loss by 25 to 50 percent.

Over time, the 'shelf' extends out from the shore in a long-lasting floating ledge. The ledge can become very thick depending on the size of the ice pieces and the size of the air pockets. The ice sheet can be stabilized by grounding on shore or lake bottom, through additional freezing from seaspray, precipitation and undersurface ice formation and through melt/refreezing cycles from solar heating and weather variations. Therefore, an ice shelf can vary from a large flat surface to a jumbled pile of blocks with parallel ridges.

Citizens Energy currently provides free home heating oil for the elderly and the poor living in Massachusetts and other cold weather states. In addition, the organization provides a prescription drugs assistance program, and has started solar heating projects in Jamaica and Venezuela. In February 2014, Citgo and the Government of Venezuela launched its ninth annual Heating Oil Program in partnership with Citizens Energy; since its inception in 2005 the program has covered the donation of 235 million gallons of heating oil to 1.8 million Americans. The heating oil contributions from Venezuela ended in 2017.

Another agent is the buoyant convective upward motion caused by significant daytime solar heating at surface level, or by relatively high absolute humidity. Incoming short-wave radiation generated by the sun is re- emitted as long-wave radiation when it reaches Earth's surface. This process warms the air closest to ground and increases air mass instability by creating a steeper temperature gradient from warm or hot at surface level to cold aloft. This causes it to rise and cool until temperature equilibrium is achieved with the surrounding air aloft.

Dust storms are not limited to Earth and have been known to form on other planets such as Mars. These dust storms can extend over larger areas than those on Earth, sometimes encircling the planet, with wind speeds as high as . However, given Mars' much lower atmospheric pressure (roughly 1% that of Earth's), the intensity of Mars storms could never reach the kind of hurricane-force winds that are experienced on Earth. Martian dust storms are formed when solar heating warms the Martian atmosphere and causes the air to move, lifting dust off the ground.

The ecovillage is centered on a Community Hub, from which courses, conferences and open days are run. It was constructed using local timber, straw bale insulation and locally sourced aggregate as well as incorporating various green technologies (such as a masonry stove, passive solar heating and a wood-fired kitchen). Funding for the Community Hub came from the Department of Energy and Climate Change. The project has been designed as a replicable template - with each household purchasing a 1000-year agricultural lease from the organisation which provides them with autonomy and security.

Similarly, as the comet rotated, Philae was not always in sunlight and thus not always generating enough power via its solar panels to receive and transmit signals. ESA controllers continued to try to establish a stable contact duration of at least 50 minutes. Had Philae landed at the planned site of Agilkia in November 2014, its mission would probably have ended in March 2015 due to the higher temperatures of that location as solar heating increased. , Philae key remaining experiment was to drill into the comet's surface to determine its chemical composition.

In this roofing investigation application, infrared thermographic data was collected during daytime hours, on both sunny and rainy days. This data collection time allowed for solar heating of the roof, and any entrapped water within the roofing system, during the daylight hours. IR data was observed until the roof had sufficiently warmed to allow detection of the entrapped wet areas because of their ability to collect and store more heat than the dry insulated areas. The wet areas would also transfer the heat at a faster rate than the dry insulated roof areas.

The four different generations of district heating systems and their energy sources Electrical heating systems occur less commonly and are practical only with low-cost electricity or when ground source heat pumps are used. Considering the combined system of thermal power station and electric resistance heating, the overall efficiency will be less than for direct use of fossil fuel for space heating. Some other buildings utilize central solar heating, in which case the distribution system normally uses water circulation. Alternatives to such systems are gas heaters and district heating.

Rammed earth can contribute to the overall energy efficiency of edifices: the density, thickness, and thermal conductivity of rammed earth render it an especially suitable material for passive solar heating. Warmth requires almost 12 hours to be conducted through a wall thick. Rammed-earth construction may also reduce the ecological impacts of deforestation and the toxicity of artificial materials associated with conventional construction techniques. Although it has low greenhouse gas emissions in theory, transportation and the production of cement can add significantly to the overall emissions of modern rammed earth construction.

Passive annual heat storage is a building concept theorized to create a year-round constant temperature in an earth shelter by means of direct gain passive solar heating and a thermal battery effect lasting several months. It is claimed that an earth shelter designed according to these principles would store the Sun's heat in the summer and release it slowly over the winter months without need for other forms of heating. This method was first described by inventor and physicist John Hait in his 1983 book.Passive annual heat storage: Improving the design of earth shelters.

The development consists of a terrace of five single story dwellings which are earth-sheltered at the rear (North), so that the ground surface slopes and blends smoothly into the field at the back. The houses have passive solar heating (a combination of high thermal mass and the south-facing conservatory) removing the need for a space heating system and the greatest factor in lowering energy use. Each house is 6 metres deep with a 19 metre conservatory to the south. This runs the full width of each dwelling.

Map of pressure systems across North America A pressure system is a relative peak or lull in the sea level pressure distribution. The surface pressure at sea level varies minimally, with the lowest value measured and the highest recorded . High- and low-pressure systems evolve due to interactions of temperature differentials in the atmosphere, temperature differences between the atmosphere and water within oceans and lakes, the influence of upper-level disturbances, as well as the amount of solar heating or radiationized cooling an area receives. Pressure systems cause weather to be experienced locally.

Note that the meridional circulation is much lower than the zonal circulation, which transports heat between the day and night sides of the planet All winds on Venus are ultimately driven by convection. Hot air rises in the equatorial zone, where solar heating is concentrated and flows to the poles. Such an almost-planetwide overturning of the troposphere is called Hadley circulation. However, the meridional air motions are much slower than zonal winds. The poleward limit of the planet-wide Hadley cell on Venus is near ±60° latitudes.

Animation of cloud evolution from cumulus humilis to cumulonimbus capillatus incus One agent is the convective upward motion of air caused by daytime solar heating at surface level. Airmass instability allows for the formation of cumuliform clouds that can produce showers if the air is sufficiently moist. On moderately rare occasions, convective lift can be powerful enough to penetrate the tropopause and push the cloud top into the stratosphere. Frontal and cyclonic lift occur when stable air is forced aloft at weather fronts and around centers of low pressure by a process called convergence.

Cometary nuclei vary in size from a few hundreds of metres across or less to many kilometres across. When they approach the Sun, large amounts of gas and dust are ejected by cometary nuclei, due to solar heating. A crucial factor in how bright a comet becomes is how large and how active its nucleus is. After many returns to the inner Solar System, cometary nuclei become depleted in volatile materials and thus are much less bright than comets which are making their first passage through the Solar System.

The Free Life attempt was the first use of a Roziere style balloon for an Atlantic attempt, built by Mark Semich, using a combination of helium and hot air. Below the spherical helium gas cell is a conical sleeve where air can be heated by burners in the same way as a normal hot air balloon. By varying the hot air temperature, altitude can be maintained without having to release helium or to drop ballast. The burners are principally used to compensate for the lack of solar heating at night.

The first production Advanced Passenger Train was unveiled on 7 June 1978. It was painted in a new livery with dark grey upper body and light grey lower body separated by wide white and red bands. The roof was white to reduce solar heating, and a large 'InterCity APT' logotype was positioned on the dark grey section of the power cars – 'InterCity' had no hyphen and was solid white but the 'APT' was an outline. A new 'Executive' service was part of the relaunch of the InterCity Sector on 3 October 1983.

U.S. Pat. No. 4,269,170, "Adsorption solar heating and storage"; Inventor: John M. Guerra; Granted May 26, 1981 Advantages over molten salts and other high temperature TES include that (1) the temperature required is only the stagnation temperature typical of a solar flat plate thermal collector, and (2) as long as the zeolite is kept dry, the energy is stored indefinitely. Because of the low temperature, and because the energy is stored as latent heat of adsorption, thus eliminating the insulation requirements of a molten salt storage system, costs are significantly lower.

The objective in solar heating is 163,000 m2 collector area (1995–2010).ESTIF Sun in Action II – A Solar Thermal Strategy for Europe, vol. 2 The Solar Thermal Sector Country by Country, 21 National Reports, 348 s., 4/2003 In 2006 the collector area in operation was 16,493 m2.Solar Thermal Markets in Europe (Trends and market statistics 2006) 6/2007 Solar heat in Finland was (1997–2004) 4-5 GWh and (2005) 6 GWh. Thus, Finland has installed 10% of its objective in 11 years time (1995–2010).

This suggests that a climatic shift allowed for their onset. Both polar caps shrink and regrow following the temperature fluctuation of the Martian seasons; there are also longer-term trends that are better understood in the modern era. During the southern hemisphere spring, solar heating of dry ice deposits at the south pole leads in places to accumulation of pressurized CO2 gas below the surface of the semitransparent ice, warmed by absorption of radiation by the darker substrate. After attaining the necessary pressure, the gas bursts through the ice in geyser- like plumes.

The fertilized egg grows into an embryo which remains suspended in the womb for up to three months before implantation, to delay birth until sufficient pack ice is available. Harp seal births are rapid, with recorded lengths as short as 15 seconds in duration. In order to cope with the shock of a rapid change in environmental temperature and undeveloped blubber layers, the pup relies on solar heating, and behavioral responses such as shivering or seeking warmth in the shade or even water. Newborn pups weigh on average and are long.

The Solar Building is a one-story, International Style building consisting of two main sections. The north wing, containing the main drafting room as well as the solar heating equipment, made up the main portion of the original building. It has an irregular quadrilateral cross-section with the roof and south wall both angled (at 20 and 30 degrees, respectively) in order to provide a high southern exposure for the solar collectors. The wing is framed by seven structural steel bents, spaced apart and filled in with wooden ceiling joists and masonry.

Their low mineral content sharply limits their buffering capacity and one result is that they are subject to major shifts in pH; a range between pH 4 and pH 11 is nothing unusual in some regions. Such variations are subject to the time of day and the water cycle variables. Water temperature in such shallow, exposed pools also varies dramatically according to evaporation, ambient air temperature and solar heating, as affected by the colour of the surrounding rock. Daily fluctuations between 10 °C and 40 °C are common.

The House of Tomorrow was built for the Century of Progress' 1933 Homes of Tomorrow Exhibition in Chicago, Illinois. Architect George Fred Keck's design reflected European modernism. The design conveyed the ideals of the fair and its emphasis on science and technology.House of Tomorrow, Beverly Shores-Century of Progress Architectural District; HABS No. IN-243-A; Historic American Buildings Survey, Department of the Interior; 1994, pg 2 Keck said he 'discovered' solar heating when he found workers inside the house wearing only shirtsleeves on a frigid winter day.

This deprived Skylab of most of its electrical power and also removed protection from intense solar heating, threatening to make it unusable. The first crew deployed a replacement heat shade and freed the jammed solar panels to save Skylab. This was the first time that a repair of this magnitude was performed in space. Skylab included the Apollo Telescope Mount (a multi-spectral solar observatory), a multiple docking adapter with two docking ports, an airlock module with extravehicular activity (EVA) hatches, and the orbital workshop, the main habitable space inside Skylab.

One is that water vapor may have been trapped underneath the road surface markings, causing the de-bonding of asphalt binder from the aggregate materials. Another hypothesis is that the reflectivity of the markings may create differences in solar heating and thermal expansion strains between the areas with and without markings. Small flaws caused by differential strains may be combined into longitudinal cracks along the markings. There are certain surface treatments that can make the road surface less susceptible to this type of distresses, such as slurry seals and stone mastic asphalt.

His expanded farm now spans over 45 hectares of forest gardens, including 70 ponds, and is said to be the most consistent example of permaculture worldwide. In the past he has experimented with many different animals. As a result of these experiments, there is a huge role for animals in the Holzer Permaculture. He has created some of the world's best examples of using ponds as reflectors to increase solar gain for passive solar heating of structures, and of using the microclimate created by rock outcrops to effectively change the hardiness zone for nearby plants.

In the height region between about 85 and 200 km altitude on Earth, the ionospheric plasma is electrically conducting. Atmospheric tidal winds due to differential solar heating or due to gravitational lunar forcing move the ionospheric plasma against the geomagnetic field lines thus generating electric fields and currents just like a dynamo coil moving against magnetic field lines. That region is therefore called ionospheric dynamo region.Chapman , S.J. and J. Bartels, „Geomagnetism“ , Clarendon Press, 1951 The magnetic manifestation of these electric currents on the ground can be observed during magnetospheric quiet conditions.

The highest temperature he reached was , which he found did not vary significantly when the box was carried from the top of Mt. Crammont in the Swiss Alps down to the Plains of Cournier, 4,852 feet lower in altitude and warmer in temperature, thereby establishing that the external air temperature played no significant role in this solar heating effect. In 1784, Saussure was elected a foreign member of the Royal Swedish Academy of Sciences; in 1788, a foreign member of the Royal Society of London; in 1791, an associate foreign member of l'Académie des sciences de Paris. Saussure died in 1799 in Geneva.

In passive solar building design, windows, walls, and floors are made to collect, store, reflect, and distribute solar energy in the form of heat in the winter and reject solar heat in the summer. This is called passive solar design because, unlike active solar heating systems, it does not involve the use of mechanical and electrical devices. The key to designing a passive solar building is to best take advantage of the local climate performing an accurate site analysis. Elements to be considered include window placement and size, and glazing type, thermal insulation, thermal mass, and shading.

At one time he arranged for a lion to be brought in the House. He was a sponsor of the public school funding equalization formula. He also sponsored severance taxes on finite natural resources, a higher minimum-wage law and bilingual education Other measures supported by Salman included incentives for solar heating and power systems, energy savings in public buildings, environmental improvement board powers, sulfur emissions control, radioactive materials disposal, the beverage container act and acquisition of Vermejo Park. In 1978 Salman was the main sponsor of the state's 1978 Controlled Substances Therapeutic Research Act, which allowed the medical use of marijuana.

Due to the low ambient pressures, these eruptions consist of vapor without liquid; they are made more easily visible by particles of dust and ice carried aloft by the gas. Water vapor jets have been observed near the south pole of Saturn's moon Enceladus, while nitrogen eruptions have been observed on Neptune's moon Triton. There are also signs of carbon dioxide eruptions from the southern polar ice cap of Mars. In the latter two cases, instead of being driven by geothermal energy, the eruptions seem to rely on solar heating via a solid-state greenhouse effect.

The project uses custom-built zero-pressure balloons from Global Western, made of very thin polyethylene, with denatured alcohol ballast dropped during cruise to maintain a constant altitude (although lift provided by solar heating is also used). The electronics comprise a flight computer, I2C temperature sensors, high frequency radio transmitter, electric heater, 40 AA lithium batteries, and GPS. Amateur radio operators voluntarily assist in tracking the balloons during their flights. In order to cross the ocean, the balloon must stay within the high speed jet stream winds the entire way from Knoxville, Tennessee, to Europe or Africa.

This indicates that solar heating, although very weak at Triton's great distance from the Sun, plays a crucial role. It is thought that the surface of Triton probably consists of a translucent layer of frozen nitrogen overlying a darker substrate, which creates a kind of "solid greenhouse effect". Solar radiation passes through the thin surface ice sheet, slowly heating and vaporizing subsurface nitrogen until enough gas pressure accumulates for it to erupt through the crust. A temperature increase of just 4 K above the ambient surface temperature of 37 K could drive eruptions to the heights observed.

Weather pattern of the North American Monsoon 3-second video of a lightning strike during a monsoon over Island in the Sky, Canyonlands National Park The North American Monsoon is not as strong or persistent as its Indian counterpart, mainly because the Mexican Plateau is not as high or as large as the Tibetan Plateau in Asia. However, the North American Monsoon shares most of the basic characteristics of its Indian counterpart. There is a shift in wind patterns in summer which occurs as Mexico and the southwest U.S. warm under intense solar heating. As this happens, the flow reverses.

In those areas, the intense solar heating is not strong enough to overcome a continual supply of cold water from the North Pacific Ocean moving down the west coast of North America. Winds do turn toward the land in these areas, but the cool moist air actually stabilizes the atmosphere. The monsoon pushes as far west as the Peninsular Ranges and Transverse Ranges of Southern California, but rarely reaches the coastal strip. As shown in the panorama below, a wall of thunderstorms, only a half-hour's drive away, is a common sight from the sunny skies along the coast during the monsoon.

The tandem arrangement makes launching difficult, and this complexity can lead to mission failure. The tandem balloon system is intended to increase the flight time of the zero-pressure balloon by damping the diurnal altitude variations caused by solar heating of the lifting gas and its subsequent expansion. As the balloons descend, the superpressure balloon's constant volume displaces a larger mass of the denser air, and becomes more buoyant. Likewise as they rise, the system displaces less air mass, limiting the ascent to prevent the lifting gas from expanding too far and escaping from the zero pressure balloon.

Polytunnels are mainly used in temperate regions in similar ways to glass greenhouses and row covers. Besides the passive solar heating that every polytunnel provides, every variation of auxiliary heating (from hothouse heating through minimal heating to unheated houses) is represented in current practice. The nesting of row covers and low tunnels inside high tunnels is also common. Superbay Polytunnel at Van Arnham Nurseries Polytunnels can be used to provide a higher temperature and/or humidity than that which is available in the environment but can also protect crops from intense heat, bright sunlight, winds, hailstones, and cold waves.

By late morning to early afternoon, solar heating usually is sufficient to evaporate the clouds, and the sun emerges. The phenomenon forms earliest and lasts longest at the coast, with weaker effects as it moves further inland. When the marine layer is strong and deep, clouds can fill the Los Angeles Basin and spill over into the San Fernando Valley and San Gabriel Valley, even extending into the Santa Clarita Valley and Inland Empire on exceptionally strong June Gloom mornings. If conditions are not as strong, the Basin may be filled while the valleys may be clear.

The envelope was of thick cotton, painted with aircraft dope containing aluminium to reduce solar heating, then sandpapered smooth. The gas cells were also cotton, lined with goldbeater's skins, and protected from damage by a layer containing of ramie fibre. Graf Zeppelin was long and had a total gas volume of , of which was hydrogen carried in 17 lifting gas cells (Traggaszelle), and was Blau gas in 12 fuel gas cells (Kraftgaszelle). It was built to be the largest possible airship that could fit into the company's hangar, with only between the top of the finished vessel and the hangar roof.

Simple designs include a simple glass-topped insulated box with a flat solar absorber made of sheet metal, attached to copper heat exchanger pipes and dark-colored, or a set of metal tubes surrounded by an evacuated (near vacuum) glass cylinder. In industrial cases a parabolic mirror can concentrate sunlight on the tube. Heat is stored in a hot water storage tank. The volume of this tank needs to be larger with solar heating systems to compensate for bad weather and because the optimum final temperature for the solar collector is lower than a typical immersion or combustion heater.

Solar energy technologies, such as solar water heaters, located on or near the buildings which they supply with energy, are a prime example of a soft energy technology. Solar heating systems are a well known second-generation technology and generally consist of solar thermal collectors, a fluid system to move the heat from the collector to its point of usage, and a reservoir or tank for heat storage. The systems may be used to heat domestic hot water, swimming pools, or homes and businesses.Brian Norton (2011) Solar Water Heaters: A Review of Systems Research and Design Innovation, Green.

"Usonian" usually refers to a group of approximately sixty middle-income family homes designed by Frank Lloyd Wright beginning in 1934 with the Willey House, with most considering the Herbert and Katherine Jacobs First House, 1937, to be the first true "Usonian." The "Usonian Homes" are typically small, single-story dwellings without a garage or much storage. They are often L-shaped to fit around a garden terrace on unusual and inexpensive sites. They are characterized by native materials; flat roofs and large cantilevered overhangs for passive solar heating and natural cooling; natural lighting with clerestory windows; and radiant-floor heating.

The present site was moved into in 1953 and consisted of five buildings.History: 1945-1971 A play field and several added dormitories in 1980s gave the school the room to add over 900 students bringing the total student population to over 1000. In the 1990s the campus went through massive infrastructure growth and renovation - gaining its own power plant, campus fencing, intercom system, phone system for students, parents and staff, three wells, solar heating for the dining hall and a large garden. Computers handle student records, accounts, maintenance, personnel, and other administrative areas as well as facilitating student-parent communication.

The government under Kim Jong-un has increased emphasis on renewable energy projects like wind farms, solar parks, solar heating and biomass. A set of legal regulations adopted in 2014 stressed the development of geothermal, wind and solar energy along with recycling and environmental conservation. North Korea's long-term objective is to curb fossil fuel usage and reach an output of 5 million kilowatts from renewable sources by 2044, up from its current total of 430,000 kilowatts from all sources. Wind power is projected to satisfy 15% of the country's total energy demand under this strategy.

Solar heating on the day side and radiative cooling on the night side of a planet can induce pressure difference. Thermal tides, which are the wind circulation and waves driven by such a daily-varying pressure field, can explain a lot of variability of the Martian atmosphere. Compared to Earth's atmosphere, thermal tides have a larger influence on the Martian atmosphere because of the stronger diurnal temperature contrast. The surface pressure measured by Mars rovers showed clear signals of thermal tides, although the variation also depends on the shape of the planet's surface and the amount of suspended dust in the atmosphere.

When Soldiers Grove began its relocation project in 1979, the United States was suffering from its second oil crisis in six years. In response to high energy costs, an energy task force for the Soldiers Grove relocation recommended that the new business district use solar heating. Despite the village's location in the northern state of Wisconsin, studies showed it was feasible for new buildings to achieve a majority of their heat from solar energy. Consequently, the village council, led by eco-champion Daniel Naccarato, enacted an unprecedented ordinance requiring all new commercial buildings obtain at least 50% of their heat from the sun.

Changes in markets and improvements in animal husbandry led to more Simmental cattle being raised for meat rather than cheese production. The construction of the road over the Col des Mosses (1865–71) and the construction of a new road to Bulle (1895) eased transportation. Balloon above the streets of Château-d'Œx The hospital, which had replaced the old hospital in 1926, was remodeled in 1979 into a nursing home and district hospital. At the same time, solar heating was added to the building. The municipal administration building was built in 1912, and renovated in 1958.

Richard B. Dunn Solar Telescope (formerly the Vacuum Tower Telescope at Sacramento Peak) is a scientific instrument for observing the Sun A solar tower, in the context of astronomy, is a structure used to support equipment for studying the sun, and is typically part of solar telescope designs. Generically, the term solar tower has many more uses especially for a type of power production using Earth's Sun. Solar tower observatories are also called vacuum tower telescopes. Solar towers are used to raise the observation equipment above the atmospheric disturbances caused by solar heating of the ground and the radiation of the heat into the atmosphere.

The story is narrated by a ten-year-old boy living on Earth after it has become a rogue planet, having been torn away from the Sun by a passing "dark star". The loss of solar heating has caused the Earth's atmosphere to freeze into thick layers of "snow". The boy's father had worked with a group of other scientists to construct a large shelter, but the earthquakes accompanying the disaster had destroyed it and killed the others. He managed to construct a smaller, makeshift shelter called the "Nest" for his family, where they maintain a breathable atmosphere by periodically retrieving pails of frozen oxygen to thaw over a fire.

Expansion continued in 2004 with the opening of the Malletts Creek Branch as a replacement for the Loving Branch. This branch is a unique model of sustainable design featuring solar heating, natural day lighting, a vegetated green roof, convection cooling, naturally captured and filtered storm water, native plants and grasses, and many uses of materials that are renewable resources. The Malletts Creek Branch was awarded the 2005 American Institute of Architects Michigan (AIA Michigan) Award for Sustainable Design.2005 AIA Michigan Design Award Winners In 2006, AADL opened the Pittsfield Branch, a community-based learning center serving the residents of the southwest quadrant of Ann Arbor and Pittsfield Township.

Unlike an active solar system that employs hardware and mechanical equipment to collect or transport heat, Trombe wall is a passive solar-heating system where the thermal energy flows in the system by natural means such as radiation, conduction, and natural convection. As a consequence, the wall works by absorbing sunlight on its outer face and then transferring this heat through the wall by conduction. Heat conducted through the wall is then distributed to the living space by radiation, and to some degree by convection, from the wall’s inner surface. The greenhouse effect helps this system by trapping the solar radiation between the glazing and the thermal mass.

Solar potential in Europe Solar energy in the European Union consists of photovoltaics (PV) and solar thermal energy. In 2010, the €2.6 billion European solar heating sector consisted of small and medium-sized businesses, generated 17.3 terawatt-hours (TWh) of energy, employed 33,500 workers, and created one new job for every 80 kW of added capacity.[Solar Thermal Markets in Europe Trends and Market Statistics 2010], European Solar Thermal Industry Federation (ESTIF) June 2011 p. 14-15, Figure Capacity in operation 2010/2020 During 2011, an additional 21.9 gigawatts (GW) of photovoltaics systems were connected to the grid in the European Union, a steep increase from 13.4 GW in 2010.

Upon opening in 1954, the Simms Building had an innovative heating and cooling system designed by the engineering firm of Bridgers and Paxton. During normal operation, groundwater from onsite deep wells, available at year-round, was heated or cooled as needed using a heat pump and then circulated through radiant panels built into the exterior curtain walls. In winter, the system could also take advantage of solar heating, in effect using the building's sunny southern side as a giant solar collector which could then provide heat to the northern side. At times, the heating and cooling loads were balanced so that the system could operate self- sufficiently on solar energy alone.

The symbols he used to represent trailing winds still exist in most modern day weather chart representations. In this article he identified solar heating as the cause of atmospheric motions. He also established the relationship between barometric pressure and height above sea level. His charts were an important contribution to the emerging field of information visualisation.Halley E. (1686), "An Historical Account of the Trade Winds, and Monsoons, Observable in the Seas between and Near the Tropicks, with an Attempt to Assign the Phisical Cause of the Said Winds", Philosophical Transactions, 16:153–168 Halley spent most of his time on lunar observations, but was also interested in the problems of gravity.

Due to solar heating, the elements of Earth and the inner rocky planets of the Solar System have undergone an additional depletion of volatile hydrogen, helium, neon, nitrogen, and carbon (which volatilizes as methane). The crust, mantle, and core of the Earth show evidence of chemical segregation plus some sequestration by density. Lighter silicates of aluminum are found in the crust, with more magnesium silicate in the mantle, while metallic iron and nickel compose the core. The abundance of elements in specialized environments, such as atmospheres, or oceans, or the human body, are primarily a product of chemical interactions with the medium in which they reside.

A skylight providing internal illumination Daylighting is the practice of placing windows, skylights, other openings, and reflective surfaces so that sunlight (direct or indirect) can provide effective internal lighting. Particular attention is given to daylighting while designing a building when the aim is to maximize visual comfort or to reduce energy use. Energy savings can be achieved from the reduced use of artificial (electric) lighting or from passive solar heating. Artificial lighting energy use can be reduced by simply installing fewer electric lights where daylight is present or by automatically dimming/switching off electric lights in response to the presence of daylight - a process known as daylight harvesting.

The first EVA repairs of a spacecraft were made by Charles "Pete" Conrad, Joseph Kerwin, and Paul J. Weitz on May 26, June 7, and June 19, 1973, on the Skylab 2 mission. They rescued the functionality of the launch-damaged Skylab space station by freeing a stuck solar panel, deploying a solar heating shield, and freeing a stuck circuit breaker relay. The Skylab 2 crew made three EVAs, and a total of ten EVAs were made by the three Skylab crews. They found that activities in weightlessness required about 2 times longer than on Earth because many astronauts suffered spacesickness early in their flights.

The Martian atmosphere is composed mainly of carbon dioxide and has a mean surface pressure of about 600 pascals (Pa), much lower than the Earth's 101,000 Pa. One effect of this is that Mars' atmosphere can react much more quickly to a given energy input than that of Earth's atmosphere. As a consequence, Mars is subject to strong thermal tides produced by solar heating rather than a gravitational influence. These tides can be significant, being up to 10% of the total atmospheric pressure (typically about 50 Pa). Earth's atmosphere experiences similar diurnal and semidiurnal tides but their effect is less noticeable because of Earth's much greater atmospheric mass.

However, Bridgers and Paxton believed the reduced operating costs would save money in the long run. The novel building attracted considerable attention, receiving write-ups in a number of national publications including Architectural Forum, Life, Architectural Record, Progressive Architecture, and Popular Mechanics, and directly inspired a number of subsequent active solar heating systems. Despite some minor problems, the building's heating system operated successfully for six years, even during the particularly cold and cloudy month of January 1957, which recorded only three sunny days. However, it was not as economical as Bridgers and Paxton had hoped, mainly due to the extremely low cost of fuel at the time.

The Truman St. elevation of the building, showing the location of the solar collectors (now covered) The building's active solar heating system employed an array of 56 solar thermal collectors with a total area of . The array was positioned on a south-facing exterior wall which was angled at 30 degrees to the vertical in order to catch the maximum amount of winter sunlight. The collectors were custom-fabricated aluminum panels with built-in flow channels for water to pass through. The surface of each collector was coated with low-reflectivity black paint and a layer of glass to capture the maximum amount of thermal energy.

A geothermal heat pump (GHP) or ground source heat pump (GSHP) is a central heating and/or cooling system that transfers heat to or from the ground. It uses the earth all the time, without any intermittency, as a heat source (in the winter) or a heat sink (in the summer). This design takes advantage of the moderate temperatures in the ground to boost efficiency and reduce the operational costs of heating and cooling systems, and may be combined with solar heating to form a geosolar system with even greater efficiency. They are also known by other names, including geoexchange, earth-coupled, earth energy systems.

Hadley cells within an idealized depiction of the Earth's atmospheric circulation as they may appear at equinox. In the early 18th century, George Hadley, an English lawyer and amateur meteorologist, was dissatisfied with the theory that the astronomer Edmond Halley had proposed for explaining the trade winds. What was no doubt correct in Halley's theory was that solar heating creates upward motion of equatorial air, and air mass from neighboring latitudes must flow in to replace the risen air mass. But for the westward component of the trade winds Halley had proposed that in moving across the sky the Sun heats the air mass differently over the course of the day.

The campus change was not made without controversy – the old downtown campus was an "open" campus that allowed the student body to depart and return during the school day, while the new campus is "closed". The first month in the new school featured student protests, leaky roofs, and problems with the school's (at the time) state-of-the-art solar heating system. The first class to graduate after attending all four years at the newly built high school was the class of 1981. In the year 2000, due to increasing population in the area, District 303 was split between two high schools, and St. Charles High School was renamed St. Charles East High School.

Antimatter comets thought to exist in the Oort cloud were in the 1990s hypothesized as one possible explanation for gamma ray bursts. These bursts can be explained by the annihilation of matter and antimatter microcomets. The explosion would create powerful gamma ray bursts and accelerate matter to near light speeds. These antimatter microcomets are thought to reside at distances of more than 1000 AU. Calculations have shown that comets of around 1 km in radius would shrink by 1 m if they passed the Sun with a perihelion of 1 AU. Microcomets, due to the stresses of solar heating, shatter and burn up much more quickly because the forces are more concentrated within their small masses.

Surface friction forces the surface wind to slow and turn near the surface of the Earth, blowing directly towards the low pressure, when compared to the winds in the nearly frictionless flow well above the Earth's surface. This layer, where surface friction slows the wind and changes the wind direction, is known as the planetary boundary layer. Daytime solar heating due to insolation thickens the boundary layer as winds warmed by contact with the earth's hot surface rise up and become increasingly mixed with winds aloft. Radiative cooling overnight gradually decouples the winds at the surface from the winds above the boundary layer, increasing vertical wind shear near the surface, also known as wind gradient.

William Herschel Telescope and the DOT The DOT is an open telescope, which means that the structure is physically open, and the wind can blow through. Because the wind blows along the mirror the air has a more or less constant temperature, and this prevents seeing. Conventional telescope designs have the problem that hot air from the ground (which is hotter due to solar heating) is blown up along the tower, and this causes air with different temperatures to blow along the telescope, which degrades the image. A drawback of this open structure is that the skeleton has to be very rigid (do not confuse with strong), to prevent the structure from moving in the wind.

These blooms are prevalent in the Norwegian fjords, causing satellites to pick up "white waters", which describes the reflectance of the blooms picked up by satellites. This is due to the mass of coccoliths reflecting the incoming sunlight back out of the water, allowing the extent of E. huxleyi blooms to be distinguished in fine detail. Extensive E. huxleyi blooms can have a visible impact on sea albedo. While multiple scattering can increase light path per unit depth, increasing absorption and solar heating of the water column, E. huxleyi has inspired proposals for geomimesis, because micron-sized air bubbles are specular reflectors, and so in contrast to E. huxleyi, tend to lower the temperature of the upper water column.

On 1 October 2016, Spitzer began its Observation Cycle 13, a 2½ year extended mission nicknamed Beyond. One of the goals of this extended mission was to help prepare for the James Webb Space Telescope, also an infrared telescope, by identifying candidates for more detailed observations. Another aspect of the Beyond mission was the engineering challenges of operating Spitzer in its progressing orbital phase. As the spacecraft moved farther from Earth on the same orbital path from the Sun, its antenna had to point at increasingly higher angles to communicate with ground stations; this change in angle imparted more and more solar heating on the vehicle while its solar panels received less sunlight.

Newton Crater (video-gif) Distinctive properties of recurring slope lineae (RSL) include slow incremental growth, formation on warm slopes in warm seasons, and annual fading and recurrence, showing a strong correlation with solar heating. RSL extend down slope from bedrock outcrops often following small gullies about wide, with lengths up to hundreds of meters, and some of the locations display more than 1,000 individual flows. RSL advance rates are highest at the beginning of each season, followed by much slower lengthening. RSL appear and lengthen in the late southern spring and summer from 48°S to 32°S latitudes that favor equator-facing slopes, which are times and places with peak surface temperatures from .

Satellite image of the 550-megawatt Topaz Solar Farm in California, US Global map of global horizontal irradiation. At the end of 2019, global installed solar capacity was 586 GW. Solar energy, radiant light and heat from the sun, is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, concentrated solar power (CSP), concentrator photovoltaics (CPV), solar architecture and artificial photosynthesis. Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert, and distribute solar energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air.

A seawater greenhouse is a greenhouse structure that enables the growth of crops in arid regions, using seawater and solar energy. The technique involves pumping seawater (or allowing it to gravitate if below sea level) to an arid location and then subjecting it to two processes: first, it is used to humidify and cool the air, and second, it is evaporated by solar heating and distilled to produce fresh water. Finally, the remaining humidified air is expelled from the greenhouse and used to improve growing conditions for outdoor plants. The technology was introduced by British inventor Charlie Paton in the early 1990s and is being developed by his UK company Seawater Greenhouse Ltd.

Löf became interested in solar energy at MIT, where he worked under Hoyt C. Hottel and analyzed data from MIT Solar House I. In 1943, Löf designed an early flat-plate solar heating unit and installed it on the roof of his house in Boulder, Colorado. It was called the "first solar-heated home" in the United States. In 1957, he built a house in the Cherry Hills neighborhood of Denver which used a novel method to collect and store solar heat. It was designed by architect James M. Hunter, and Löf designed a flat-plate collection system which heated air and circulated the heat to be stored in rock beds in large cardboard tubes inside the house.

The North American Monsoon is experienced as a seasonal reversal of the prevailing winds, which is usually accompanied by an increase in rainfall. Onset is usually in early July when the winds start to shift due to intense solar heating of the Southwest United States and Sea Breeze Clouds in Florida. During the winter months, the weather patterns in the Southwest United States are characterized by a semi-permanent high-pressure system with quasi-weekly weather systems moving through the area; a cold front will move through the area, followed by a gradual building of the ridge. During the monsoon months, the subtropical ridge moves northward due to the development of a thermal low from the intense solar radiation.

By the end of the 20th century solar hot water systems had been capable of meeting a significant portion of domestic hot water requirements in many climate zones. However it was only with the development of reliable low-energy building techniques in the last decades of the century that extending such systems for space heating became realistic in temperate and colder climatic zones. As heat demand reduces, the overall size and cost of the system is reduced, and the lower water temperatures typical of solar heating may be more readily used - especially when coupled with underfloor heating or wall heating. The volume occupied by the equipment also reduces, which also increases the flexibility of its location.

Hidden Villa shelters many California native plants such as this native honeysuckle Lonicera hispidula 2010 photovoltaic system, passive solar heating and cooling, trombe wall, thermal mass, and straw bale construction. Plaque commemorating 1933 founding of the Loma Prieta Chapter of the Sierra Club lies on Adobe Creek Trail above Hidden Villa Ranch. The land between Moody Road and Adobe Creek was part of the Rancho La Purísima Concepción land grant given in 1840 to José Gorgonio and his son José Ramon, Ohlone Indians of Mission Santa Clara, by Governor Juan Alvarado. George Washington Moody built Moody Road in 1867, from the Mountain View Railway station through what is now Hidden Villa Ranch to connect to Mayfield- Pescadero Road (now Page Mill Road).

Stephens also contributed the "Safe Shelter & Independent Energy" chapter for The Complete Survival Guide (1983), which was edited by ark Thiffault. In public speaking venues, newsletters, and magazines, Stephens has been associated with Harry Browne, Robert D. Kephart, James McKeever, and Mel Tappan. Stephens studied architecture at the University of Idaho, and worked in a range of architectural and engineering firms in Idaho, Washington and southern California, before establishing his own eco-home design and consulting practice. From his university days onward, he has explored and evolved techniques of active solar and passive solar heating, solar power, earth-integrated design (earth sheltering), and pioneered uses of a range of "alternative", "natural", and salvaged materials and building techniques in home and retreat construction.

Brise-soleil can comprise a variety of permanent sun-shading structures, ranging from the simple patterned concrete walls popularized by Le Corbusier in the Palace of Assembly to the elaborate wing-like mechanism devised by Santiago Calatrava for the Milwaukee Art Museum or the mechanical, pattern-creating devices of the Institut du Monde Arabe by Jean Nouvel. In the typical form, a horizontal projection extends from the sunside facade of a building. This is most commonly used to prevent facades with a large amount of glass from overheating during the summer. Often louvers are incorporated into the shade to prevent the high- angle summer sun falling on the facade, but also to allow the low-angle winter sun to provide some passive solar heating.

When the North African monsoon is at its strongest annual precipitation and subsequent vegetation in the Sahara region increase, resulting in conditions commonly referred to as the "green Sahara". For a relatively weak North African monsoon, the opposite is true, with decreased annual precipitation and less vegetation resulting in a phase of the Sahara climate cycle known as the "desert Sahara". The idea that changes in insolation (solar heating) caused by long-term changes in the Earth's orbit are a controlling factor for the long-term variations in the strength of monsoon patterns across the globe was first suggested by Rudolf Spitaler in the late nineteenth century, The hypothesis was later formally proposed and tested by the meteorologist John Kutzbach in 1981.

Both polar caps show spiral troughs, which were initially thought to form as a result of differential solar heating, coupled with the sublimation of ice and condensation of water vapor. Recent analysis of ice penetrating radar data from SHARAD has demonstrated that the spiral troughs are formed from a unique situation in which high density katabatic winds descend from the polar high to transport ice and create large wavelength bedforms. The spiral shape comes from Coriolis effect forcing of the winds, much like winds on earth spiral to form a hurricane. The troughs did not form with either ice cap, instead they began to form between 2.4 million and 500,000 years ago, after three fourths of the ice cap was in place.

Expansion of the lifting gas due to solar heating is avoided in a superpressure balloon, since the inextensible PET film allows the pressure to rise as the gas is heated, rather than allow the volume to expand. This allows them to drift with, and track, horizontal atmospheric air currents at a constant air pressure level (a constant altitude) above the Earth's surface. The electronics payload was suspended below the balloon on a tether that also acted as a high frequency band radio antenna. The GHOST payload included a sun angle sensor that varied the repetition rate of its Morse code radio signal to allow technicians on the ground to locate it using an HF receiver and a set of sun angle tables.

Orbiting bodies can also be heated by tidal heating, geothermal energy which is driven by radioactive decay in the core of the planet, or accretional heating. These internal processes will cause the effective temperature (a blackbody temperature that produces the observed radiation from a planet) to be warmer than the equilibrium temperature (the blackbody temperature that one would expect from solar heating alone). For example, on Saturn, the effective temperature is approximately 95 K, compared to an equilibrium temperature of about 63 K. This corresponds to a ratio between power emitted and solar power received of ~2.4, indicating a significant internal energy source. Jupiter and Neptune have ratios of power emitted to solar power received of 2.5 and 2.7, respectively.

The Drake Landing Solar Community (DLSC) is a planned community in Okotoks, Alberta, Canada, equipped with a central solar heating system and other energy efficient technology. This heating system is the first of its kind in North America, although much larger systems have been built in northern Europe. The 52 homes (few variation of size and style, with average above-grade floor area of 145m2) in the community are heated with a solar district heating system that is charged with heat originating from solar collectors on the garage roofs and is enabled for year-round heating by underground seasonal thermal energy storage (STES). The system was designed to model a way of addressing global warming and the burning of fossil fuels.

The essential concept of the double-skin facade was first explored and tested by the Swiss- French architect Le Corbusier in the early 20th century. His idea, which he called mur neutralisant (neutralizing wall), involved the insertion of heating/cooling pipes between large layers of glass. Such a system was employed in his Villa Schwob (La Chaux-de-Fonds, Switzerland, 1916), and proposed for several other projects, including the League of Nations competition (1927), Centrosoyuz building (Moscow, 1928–33), and Cité du Refuge (Paris, 1930). American engineers studying the system in 1930 informed Le Corbusier that it would use much more energy than a conventional air system, but Harvey Bryan later concluded Le Corbusier's idea had merit if it included solar heating.

Three main types of control exist for Orobanche aegyptiaca: chemical, cultural, and biological. Chemical control can be achieved by soil fumigation with methyl bromide. This method is effective yet is rarely used because only a shallow layer of the soil is affected, it is a costly treatment, and methyl bromide poses environmental concerns. Another form of chemical control is soil solarization, which is a solar heating of the soil by placing clear polyethylene sheets over moist soil.Sedigheh S, Aptin R, Zoheir Y.A, Application Soil Solarization, on the Control of Egyptian Broomrape in Greenhouse, International Journal of Natural and Engineering Sciences 3 (1): 59-64, 2009 This kills the majority of seeds that are viable and induces secondary dormancy in the rest.

Passive solar technologies were incrementally refined and greatly improved during the 20th century, boosted by the motivation of (and aided by) the development of 3D computer modelling techniques. At the start of the 21st century, passive solar building design has received greater interest. U.S. Solar Energy Tax Credits were reinstated in 2005,Department of Energy - Tax Breaks and the 2007 Energy Bill provided more funding for solar energy research and solar air conditioning. The U.S. Department of Energy's 2007 "Thermal Performance of the Exterior Envelopes of Whole Buildings International Conference" presented a comprehensive workshop on "Three Decades of Passive Solar Heating and Cooling Lessons Learned" Since 1978, roughly 300,000 U.S. buildings have demonstrated at least some passive solar design features (although over 25 million U.S. buildings have been constructed since then without using these techniques).

Mars' atmosphere is so thin and wispy that solar heating of dust and ice in the atmosphere - not heating of the atmospheric gases - is more important in driving weather. Small, suspended particles of dust and water ice - aerosols - intercept 20–30% of incoming sunlight, even under relatively clear conditions. So variations in the amounts of these aerosols have a huge influence on climate. CRISM has taken three major kinds of measurements of dust and ice in the atmosphere: targeted observations whose repeated views of the surface provide a sensitive estimate of aerosol abundance; special global grids of targeted observations every couple of months designed especially to track spatial and seasonal variations; and scans across the planet's limb to show how dust and ice vary with height above the surface.

The glazing allows all of that heated air from the first stage to be directed through a second set of transpired collectors for a second stage of solar heating. Another innovation is to recover heat from the PV modules (which is often four times more than the electrical energy produced by the PV module) by mounting the PV modules onto the solar air system. In cases where there is a heating requirement, incorporating a solar air component into the PV system provides two technical advantages; it removes the PV heat and allows the PV system to operate closer to its rated efficiency (which is 25 C); and it decreases the total energy payback period associated with the combined system because the heat energy is captured and used to offset conventional heating.

In those countries where growing dependence on imported gas is a pressing energy security issue, renewable energy technologies can provide alternative sources of electric power production as well as displacing electricity demand through production of direct heat. The IEA suggests that the direct contribution that renewable energy can make to domestic or commercial space heating and industrial process heat should be examined more closely. Heat from solar, geothermal sources, and heat pumps, is increasingly economic but is often overlooked in government programmes that promote public acceptance and provide incentives for renewable electricity and energy efficiency. Solar heating systems are a well known technology and generally consist of solar thermal collectors, a fluid system to move the heat from the collector to its point of usage, and a reservoir or tank for heat storage.

12-ton pond loop system being sunk to the bottom of a pond A closed pond loop is not common because it depends on proximity to a body of water, where an open loop system is usually preferable. A pond loop may be advantageous where poor water quality precludes an open loop, or where the system heat load is small. A pond loop consists of coils of pipe similar to a slinky loop attached to a frame and located at the bottom of an appropriately sized pond or water source. Artificial ponds (costing €30/m³) are used as heat storage (up to 90% efficient) in some central solar heating plants, which later extract the heat (similar to ground storage) via a large heat pump to supply district heating.

The convective planetary boundary layer (CPBL), also known as the daytime planetary boundary layer (or simply convective boundary layer, CBL, when in context), is the part of the lower troposphere most directly affected by solar heating of the earth's surface. This layer extends from the earth surface to a capping inversion that typically locates at a height of 1–2 km by midafternoon over land. Below the capping inversion (10-60% of CBL depth, also called entrainment zone in the daytime), CBL is divided into two sub-layers: mixed layer (35-80% of CBL depth) and surface layer (5-10% of CBL depth). The mixed layer, the major part of CBL, has a nearly constant distribution of quantities such as potential temperature, wind speed, moisture and pollutant concentration because of strong buoyancy generated convective turbulent mixing.

The convective condensation level (CCL) results when strong surface heating causes buoyant lifting of surface air and subsequent mixing of the planetary boundary layer, so that the layer near the surface ends up with a dry adiabatic lapse rate. As the mixing becomes deeper, it will get to the point where the LCL of an air parcel starting at the surface is at the top of the mixed region. When this occurs, then any further solar heating of the surface will cause a cloud to form topping the well-mixed boundary layer, and the level at which this occurs is called the CCL. If the boundary layer starts off with a stable temperature profile (that is, with a lapse rate less than the dry adiabatic lapse rate), then the CCL will be higher than the LCL.

The Spittelau incineration plant is one of several plants that provide district heating in Vienna. Animated image showing how district heating works Biomass fired district heating power plant in Mödling, Austria Coal heating plant in Wieluń (Poland) The cancelled Russian Gorky Nuclear Heating Plant in Fedyakovo, Nizhny Novgorod Oblast District heating (also known as heat networks or teleheating) is a system for distributing heat generated in a centralized location through a system of insulated pipes for residential and commercial heating requirements such as space heating and water heating. The heat is often obtained from a cogeneration plant burning fossil fuels or biomass, but heat-only boiler stations, geothermal heating, heat pumps and central solar heating are also used, as well as heat waste from nuclear power electricity generation. District heating plants can provide higher efficiencies and better pollution control than localized boilers.

Description: Solar heating is the usage of solar energy to provide space or water heating. 2016 At present the EU is second after China in the installations. 2010 If all EU countries used solar thermal as enthusiastically as the Austrians, the EU's installed capacity would already be 91 GWth (130 million m2 today, far beyond the target of 100 million m2 by 2010, set by the White Paper in 1997). 2008 The research efforts and infrastructure needed to supply 50% of the energy for space and water heating and cooling across Europe using solar thermal energy was set out under the aegis of the European Solar Thermal Technology Platform (ESTTP). Published in late December 2008, more than 100 experts developed the strategic research agenda (SRA), which includes a deployment roadmap showing the non-technological framework conditions that will enable this ambitious goal to be reached by 2050.

Because of gravitational sinking of particulate material (such as plankton, dead or fecal material), nutrients are constantly lost from the photic zone, and are only replenished by mixing or upwelling of deeper water. This is exacerbated where summertime solar heating and reduced winds increases vertical stratification and leads to a strong thermocline, since this makes it more difficult for wind mixing to entrain deeper water. Consequently, between mixing events, primary production (and the resulting processes that leads to sinking particulate material) constantly acts to consume nutrients in the mixed layer, and in many regions this leads to nutrient exhaustion and decreased mixed layer production in the summer (even in the presence of abundant light). However, as long as the photic zone is deep enough, primary production may continue below the mixed layer where light-limited growth rates mean that nutrients are often more abundant.

A net zero-energy building (ZEB) is a building that over a year does not use more energy than it generates. The first 1979 Zero Energy Design building used passive solar heating and cooling techniques with air-tight construction and super insulation. A few ZEB's fail to fully exploit more affordable conservation technology and all use onsite active renewable energy technologies like photovoltaic to offset the building's primary energy consumption. Passive House and ZEB are complementary synergistic technology approaches, based on the same physics of thermal energy transfer and storage: ZEBs drive the annual energy consumption down to 0 kWh/m2 with help from on- site renewable energy sources and can benefit from materials and methods which are used to meet the Passive House demand constraint of 120 kWh/m2 which will minimize the need for the often costly on-site renewable energy sources.

The nozzle of hot water rockets must be able to withstand high pressure, high temperatures and the particularly corrosive nature of hot water. The simplest design has a pressurised water tank where the water is heated before launch; however, this gives a very low exhaust velocity since the high latent heat of vaporization means that very little actual steam is produced and the exhaust consists mostly of water, or if high temperatures and pressures are used, then the tank is very heavy. More complex designs can involve passing the water through pumps and heat exchangers and employing nuclear reactors or solar heating; it is estimated that these can give a specific impulse of over 195 s Isp,AIAA 97-3172, "Nuclear-Heated Steam Rocket Using Lunar Ice" Anthony Zuppero, which is still well below the standards of more complex designs, for example the 465 s of the hydrogen-oxygen Vinci engine.

The mesopause is the point of minimum temperature at the boundary between the mesosphere and the thermosphere atmospheric regions. Due to the lack of solar heating and very strong radiative cooling from carbon dioxide, the mesosphere is the coldest region on Earth with temperatures as low as -100 °C (-148 °F or 173 K).International Union of Pure and Applied Chemistry. "mesosphere". Compendium of Chemical Terminology Internet edition The altitude of the mesopause for many years was assumed to be at around 85 km (53 mi.), but observations to higher altitudes and modeling studies in the last 10 years have shown that in fact the mesopause consists of two minima - one at about 85 km and a stronger minimum at about 100 km (62 mi). Another feature is that the summer mesopause is cooler than the winter (sometimes referred to as the mesopause anomaly).

Between 2008 and 2013, researchers from Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Italy, the Republic of Korea, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland, the United Kingdom and the US were working together in the joint research program “Towards Net Zero Energy Solar Buildings” under the umbrella of International Energy Agency (IEA) Solar Heating and Cooling Program (SHC) Task 40 / Energy in Buildings and Communities (EBC, formerly ECBCS) Annex 52 in order to bring the Net ZEB concept to market viability. The joint international research and demonstration activities are divided in subtasks. The objective was to develop a common understanding, a harmonized international applicable definition framework (Subtask A, see definitions methodology “Net Zero Energy Building” above), design process tools (Subtask B), advanced building design and technology solutions and industry guidelines for Net ZEBs (Subtask C). The scope encompasses new and existing residential and non-residential buildings located within the climatic zones of the participating countries.

During the flyby of July 14, 2005, the Composite Infrared Spectrometer (CIRS) found a warm region near the south pole. Temperatures in this region ranged from 85–90 K, with small areas showing as high as , much too warm to be explained by solar heating, indicating that parts of the south polar region are heated from the interior of Enceladus. The presence of a subsurface ocean under the south polar region is now accepted, but it cannot explain the source of the heat, with an estimated heat flux of 200 mW/m2, which is about 10 times higher than that from radiogenic heating alone. Heat map of the south polar fractures, dubbed 'tiger stripes' Several explanations for the observed elevated temperatures and the resulting plumes have been proposed, including venting from a subsurface reservoir of liquid water, sublimation of ice, decompression and dissociation of clathrates, and shear heating, but a complete explanation of all the heat sources causing the observed thermal power output of Enceladus has not yet been settled.

South and East view of an Earthship passive solar home Typical floorplan An Earthship is a brand of passive solar earth shelter that is made of both natural and upcycled materials such as earth-packed tires, pioneered by architect Michael Reynolds. Earthships are predicated upon the idea that there are six human needs which can be addressed through environmentally sustainable building design: #Energy: Thermal and/or solar heating and cooling, solar and wind electricity #Garbage Management: Reuse and recycling built into construction and daily living #Sewage Treatment: Self-contained sewage treatment and water recycling #Shelter: Building with natural and recycled materials #Clean Water: Water harvesting and long term storage #Food: In-home organic food production capability Earthship structures are intended to be "off-the-grid-ready" homes, with minimal reliance on public utilities and fossil fuels. They are constructed to use available natural resources, especially energy from the sun and rain water. They are designed with thermal mass construction and natural cross-ventilation to regulate indoor temperature, and the designs are intentionally uncomplicated and mainly single-story, so that people with little building knowledge can construct them.
