Scientists are learning how to turn the chill of outer space into a quiet source of electricity, using the night sky itself as a heat sink. By carefully managing how surfaces shed heat after dark, ...

About 600 sheep will soon take over landscaping duties at Louisiana's newest solar energy facility in Lafitte.

Nearly 4.5 million years ago, two large, hot stars brushed tantalizingly close to Earth's sun. They left behind a trace in ...

Abstract: The device that uses the energy from the sun to heat air is a solar air heater (SAH). However, its slow heat transmission rate frequently limits its efficiency. To increase thermal ...

For the hot end, an aluminium mount was pressed into soil, transferring the Earth’s ambient heat to the engine’s bottom plate. At the cold end, the researchers attached a black-coated plate that ...

Korean researchers revealed that efficiency losses in heterojunction solar cells arise from two coexisting defect types – dangling bonds and weak silicon-silicon bonds. Their findings explain how ...

Abstract: Modeling of three-dimensional (3D) finned double-pass solar air heater using the finite element method (FEM) based simulation program COMSOL Multiphysics is proposed and compared with the ...
