2. Solar water heating - Wikipedia

   en.wikipedia.org/wiki/Solar_water_heating

   Solar water heating ( SWH) is heating water by sunlight, using a solar thermal collector. A variety of configurations are available at varying cost to provide solutions in different climates and latitudes. SWHs are widely used for residential and some industrial applications. [ 1][ 2]

3. Thermosiphon - Wikipedia

   en.wikipedia.org/wiki/Thermosiphon

   Thermosiphon. Thermosiphon (or thermosyphon) is a method of passive heat exchange, based on natural convection, which circulates a fluid without the necessity of a mechanical pump. Thermosiphoning is used for circulation of liquids and volatile gases in heating and cooling applications such as heat pumps, water heaters, boilers and furnaces ...

4. 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. 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“.

6. Solar controller - Wikipedia

   en.wikipedia.org/wiki/Solar_controller

   Solar controller. A solar controller is an electronic device that controls the circulating pump in a solar hot water system to harvest as much heat as possible from the solar panels and protect the system from overheating. The basic job of the controller is to turn the circulating pump on when there is heat available in the panels, moving the ...
