Compact heat pumps that slot into windows could be a planet-friendly way to efficiently heat and cool apartment buildings without breaking the bank, experts say.

The Italian manufacturer said its new WWMG heat pump system has a coefficient of performance of up to 4.98 and an energy efficiency rating of 16.30 BTU/Wh.

Quite some years ago I examined how, if we know the specific heat capacity of a particular thing, we can make an estimate of the time constant of that particular thing undergoing a thermal excursion ...

A research group has successfully developed a high-capacity capacitor, an energy storage device -- using a solid electrolyte with high deformability -- that can operate at high temperatures. With this ...
