  2. Solar water heating - Wikipedia

    en.wikipedia.org/wiki/Solar_water_heating

    When a solar water heating and hot-water central heating system are used together, solar heat will either be concentrated in a pre-heating tank that feeds into the tank heated by the central heating, or the solar heat exchanger will replace the lower heating element and the upper element will remain to provide for supplemental heat. However ...

  3. Atmospheric water generator - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_water_generator

    State-of-the-art AWG for home use. An atmospheric water generator (AWG), is a device that extracts water from humid ambient air, producing potable water. Water vapor in the air can be extracted either by condensation - cooling the air below its dew point, exposing the air to desiccants, using membranes that only pass water vapor, collecting fog, [1] or pressurizing the air.

  4. Passive solar building design - Wikipedia

    en.wikipedia.org/wiki/Passive_solar_building_design

    Fundamental passive solar hot water heating involves no pumps or anything electrical. It is very cost effective in climates that do not have lengthy sub-freezing, or very-cloudy, weather conditions. [35] Other active solar water heating technologies, etc. may be more appropriate for some locations.

    Solar earnings have started to creep out and, to my surprise, a rising tide hasn't lifted all boats. SunPower reported stronger-than-expected earnings last week, and Suntech Power (NYS: STP ...

  6. Solar-powered Stirling engine - Wikipedia

    en.wikipedia.org/wiki/Solar-powered_Stirling_engine

    NASA patented a type of solar-powered Stirling engine on August 3, 1976. It used solar energy to pump water from a river, lake, or stream. [1] The purpose of this apparatus is to “provide a low-cost, low-technology pump having particular utility in irrigation systems employed in underdeveloped arid regions of the earth…[using] the basic principles of the Stirling heat engine“.

  7. Solar thermal collector - Wikipedia

    en.wikipedia.org/wiki/Solar_thermal_collector

    The term "solar collector" commonly refers to a device for solar hot water heating, but may refer to large power generating installations such as solar parabolic troughs and solar towers or non-water heating devices such as solar cookers or solar air heaters. [1] Solar thermal collectors are either non-concentrating or concentrating.

  8. Solar thermal energy - Wikipedia

    en.wikipedia.org/wiki/Solar_thermal_energy

    The heated water can then be used in homes. The advantage of solar thermal is that the heated water can be stored until it is needed, eliminating the need for a separate energy storage system. [1] Solar thermal power can also be converted to electricity by using the steam generated from the heated water to drive a turbine connected to a ...

  9. Variable renewable energy - Wikipedia

    en.wikipedia.org/wiki/Variable_renewable_energy

    Normally it is windiest at night and during cloudy or stormy weather, and there is more sunshine on clear days with less wind. [76] Besides, wind energy has often a peak in the winter season, whereas solar energy has a peak in the summer season; the combination of wind and solar reduces the need for dispatchable backup power. [77]
