That's very interesting to see! The first time I read about acoustic heat pumps was when the Dutch governments' research arm spun off their start-up: Blue Heart: https://www.blueheartenergy.com/ https://www.blueheartenergy.com/ I had no idea multiple companies were pursuing this. That's great! If we can replace every gas boiler with a acoustic heat pump that can produce 70 degree water that will enormously speed up the electrification of domestic heating in Europe.
