Several companies are developing thermo acoustic heatpumps that will have some advantages over regular heatpumps. They should produce less noise, don't use greenhouse gasses and work in a wider range of temperatures.

- DrScientist 3y agoAnybody got any actual experience of these yet?
- hasmanean 3y agoLBNL had a solid state thermoacoustic resonator the size of a coin, which I read about but never saw it in the market. It was supposed to be able to extract heat from anywhere.
- rihegher 3y agoEquium is using helium, a non renewable gas. Not a greenhouse gas but not really sustainable either.
- bill38 3y agoThey fill the core of their heat pump with helium at 30+ bars and seal it. That's all. It's not used continuously. So not a big quantity used.
