University of Utah physicists have developed small devices that turn heat into sound and then into electricity. Thermoacoustic prime movers hold promise for converting waste heat into electricity, ...

Heat pumps are too loud to be installed in millions of homes under the government's own noise guidelines, a report has warned. As part of their commitment to Net Zero, the government has announced it ...

This may not fit in "other hardware", but this seemed to be the closest fit, so here it is. We got an outdoor heat pump with a heat strip/air handler installed at our house last year. It's working ...

WEST LAFAYETTE, Ind. — A solid can serve as a medium for heat and sound wave interactions just like a fluid does for thermoacoustic engines and refrigerators – resulting in leak-free machines that can ...

Physicists at MIT have spotted the second sound of a superfluid. Besides being pleasantly alliterative, the phenomenon may explain how heat moves through certain rare materials on Earth and deep in ...
