Experimental device generates electricity from the coldness of the universe
- PaulHoule 7y agoSome notes: This kind of device depends on a clear night sky, the same way that a solar panel depends on a sunny day. Also there is some precedent for devices that use the cold of the night sky to freeze water and then use that for refrigeration. The trick is getting good thermal coupling to the sky and also eliminating coupling to the rest of the environment.
