The quantum advantage: Coherent superposition in quantum heat engines can enhance power output over classical machines. Credit: iStock Traffic-Analyzer Heat engines have had a huge impact on everyday ...

When French engineer Sadi Carnot calculated the maximum efficiency of a heat engine in 1824, he had no idea what heat was. In those days, physicists thought heat was a fluid called caloric. But Carnot ...

Ever since the invention of water mills in antiquity, through the development of the steam engine in the 18th century, and up to today’s turbines, many power generators rely on the principle of ...

Heat flows from hot to cold objects. When a hot and a cold body are in thermal contact, they exchange heat energy until they reach thermal equilibrium, with the hot body cooling down and the cold body ...

For the first time, a quantum engine has outperformed its traditional equivalent, without any special tweaks to its environment. The device harnesses the weird physics of very small objects to produce ...
