Interesting additional tidbit: theoretical coefficient of power is around 20 for this tech vs 3 for what we use. Problem: heat is absorbed and dissipated at the same place, so you still do need something that circulates it around, even if you don’t need a compressor anymore.
Absolutely, that’s why I’m mentioning it is a theoretical coefficient. It is worth noticing that the compressor, which is the part that’s being replaced here, is the main user of energy in a typical heat pump. So there is hope that if we get to the same level of engineering efficiency, we can get a very efficient system in the future. Maybe not up to 20, but certainly better than what we have now, and with a mechanically very troublesome part gone.
