Researchers have demonstrated a way to generate nighttime power by exploiting an often-overlooked temperature difference between Earth and the sky.
Their approach uses a specialized engine to tap into this subtle energy flow, revealing possibilities that don’t depend on sunlight or conventional fuels.

Researchers have created a device that generates mechanical power at night by harnessing the natural temperature difference between warm ground and the cold of outer space.
Engineers at the University of California, Davis, have created a device capable of producing mechanical energy at night by taking advantage of the warmth near the ground and the extreme cold of outer space. This approach could support practical uses such as moving air through greenhouses or other structures. The research was recently published in the journal Science Advances.
