The entire 10 paragraph article is based around a single tweet from Musk and doesn't explain a single thing about how the heat pump in the headline works.
You could buy a mini split heat pump from mitsubishi today. Five units of heat for every one of electricity. Rock solid reliability. I'm not sure it needs reinventing. What it needs is a better service industry so you can get them installed and maintained cheaply. Cheap installation, maintenance and repairs of the heat pumps we already have, that would change the world.
You _should_ think about heat pumps for HVAC in your home, especially if it's well-insulated (if not, think about insulation and heat pumps). But you should buy one made by Mitsubishi or Fujitsu, which are already amazing.
Flagged because all this article is, is some shallow quotes from Elon's Twitter and statements like "people are speculating how it works!" There is no new information nor interesting analysis.
I really don’t understand quite what’s going on here - most home heating and cooling in my country has used heat pumps for years, isn’t that the case in the US?
