I expected more from Nature.

The core of this device is a Peltier heat pump.

I'm sure it's great for keeping cool in the summer, but there is no way they'll ever work out for cooling buildings. They're fundamentally inefficient due to needing to be built of materials that conduct heat in one direction and insulate in another, while simultaneously conducting electricity and having a large bandgap. Such materials have not been found and are unlikely to exist.

Anyone technical proofing the article should have been aware of that, and should not have allowed such claims to get into the article.

Single phase gas turbine refrigeration can theoretically get to the Carnot efficiency limit, and in reality gets close to it.
