Since ancient times, people have found ways to use the sun’s heat to stay warm or keep cool. They built homes from clay and other materials that hold heat well, and they placed them in ways that ...

Solar thermal energy is the process of concentrating sunlight to create heat, which can be used to create electricity or to heat a home, its water supply and more. Solar thermal energy can be used as ...

A British-Chinese research group has developed a novel heat pump concept consisting of a heat pump, the PCM tank, and tube solar heat collectors. Intended for demand shifting in space heating and ...

The novel heat pump concept combines solar energy with chemical storage and reportedly consume 75% less electricity than conventional heat pumps. The system relies on a battery and a heat storage tank ...

Researchers have built a pilot-scale solar reactor that produces usable heat and oxygen, in addition to generating hydrogen with unprecedented efficiency for its size. A parabolic dish on the EPFL ...
