Harvard proposes device to harness some of the 100 million gigawatts of infrared heat lost into outer space

Finding a renewable heat source to provide constant power has long been the goal of many scientists. The sun is Earth’s greatest source of heat energy, but what about providing power through the night?

Researchers at the Harvard School of Engineering and Applied Sciences (SEAS) have envisioned a device that would harvest energy from Earth’s infrared emissions into outer space.
