The device is one of the first to test how quantum effects, which govern the behavior of particles on the smallest scale, might one day be exploited to enhance the performance of nanotechnologies.

A group of researchers led by the Chinese Academy of Sciences (CAS) has developed a heat-driven thermoacoustic refrigerator/heat pump (HDTAR/HDTAHP) for high heating-temperature operation. They ...

Physicists in the Netherlands have built a heat engine that might be the tiniest ever created. Based on “piezoresistive” silicon, and smaller than a typical biological cell, the engine could find ...

Heat engines are ubiquitous as they lie at the core of cars, aircraft, refrigerators, power plants and miniature motors. But they are currently limited by Carnot's maximum efficiency rule, according ...

The heat transfer "fluid" doesn't need to be a liquid. Blowing (not sucking) air through the copper tube with a fan that's switched on and off by the temperature in the "fridge" side would work fine ...
