Breakthrough device can generate electricity from the night sky
Excerpt:An innovative new device is able to generate electricity from the night sky, according to a new study. The research, published in Joule, highlights a new device that uses radiative cooling and is able to generate enough electricity for an LED light bulb, even at night. "Remarkably, the device is able to generate electricity at night, when solar cells don't work," the study's lead author, Aaswath Raman, said in a statement. "Beyond lighting, we believe this could be a broadly enabling approach to power generation suitable for remote locations, and anywhere where power generation at night is needed." (...) Radiative cooling, as described by Space.com, allows a surface to pass its heat to the atmosphere and is cooler than the air that surrounds it. "This phenomenon explains how frost forms on grass during above-freezing nights, and the same principle can be used to generate electricity, harnessing temperature differences to produce renewable electricity at night, when lighting demand peaks," the statement added. [I’ll be damned. John Galt lives, after all. In the book Atlas Shrugged, that character has invented a power supply that draws electricity from ambient static in the air. This must be that concept’s 1st cousin. Ron P.]
