This isn't new. In fact the same authors already started a company called Skycool that was featured here in a story like 2 years ago. It uses a special coated/layered radiative plate that's specially tuned to an atmospheric transparency window to dump heat to the sky.
The problem is that where this would be economically viable, you would generally already choose to use solar panels for the electricity -- cheaper and similarly/more efficient.
- Zenst 8y agoWhilst the raw efficiency of peltiers and solar panels weigh in the favour of solar panels - this design just has to point to the sky. Which for some situations, may make it more viable after all. Ships may be a use for this. But then I'm not up to date on the state of play in peltier advances. I've read some fascinating developments in rectenna's, though no efficiency numbers jumping out. But something that could completely change this whole area of electricity generating. Could this design be adapted to any new tech though if something wow around the corner jumps out as being x better than the best peltier. Maybe from what I can tell, but for now it has some niche uses without a doubt, but you won't see them in your neibours back yard or roof anytime soon if ever.
