Mechanical power by linking Earth's warmth to space
Davis CA (SPX) Nov 13, 2025 Engineers at the University of California, Davis, have invented a device that can generate mechanical power at night by linking the natural warmth around us to the cold depths of space. The invention could be used, for example, to ventilate greenhouses or other buildings. The work is described Nov. 12 in Science Advances. The invention is a type of machine called a Stirling engine. Other machines such as internal combustion engines generate power from a large heat gradient, said Jeremy Munday, pro ... read more |
