Equium, a French startup, has developed a new thermo-acoustic heat pump core that reportedly produces 3 kW to 4 kW of heat for every kilowatt-hour of power it consumes. The novel heat pump can purportedly reach higher temperatures than existing heat pumps, without the need for refrigerants. It works with a high-fidelity (Hi-Fi) speaker powered by electricity that creates an acoustic wave in a closed-pressure vessel filled with helium, which keeps the device cool. The refrigerant-free device could generate domestic hot water at temperatures of up to 80 C.
