Physicists May Have Found New Way To Turn Earth's Radiation Into Energy

By Hunter Stuart

Our planet is warm. Outer space is cold. Can we take that heat difference and turn it into electricity?

Physicists at Harvard University may have found a way to do just that. They’ve proposed in a new study how to harvest the Earth’s thermal infrared radiation, and convert it into direct-current (DC) power.

“It’s not at all obvious, at first, how you would generate DC power by emitting infrared light in free space toward the cold,” study co-author Dr. Federico Capasso, a professor of applied physics and senior research fellow in electrical engineering at …read more
