Lots of comments here jumping at impossible/perpetual motion machine etc Think of it as mining the air/water for heat energy and turning it to electricity. No one said energy is being made from nothing. This is not being touted as a solution to climate change. To rephrase the idea, is the following equation possible: heat pump running costs <= heat extracted x electricity generation efficiency At a single human scale there is near infinite air/water heat energy to run through the device. But could you do it efficiently enough? This is the closest thing I could find on short notice: https://www.pv-magazine.com/2021/08/19/the-worlds-hottest-heat-pump/ https://www.pv-magazine.com/2021/08/19/the-worlds-hottest-he...
