Almost exactly 200 years ago, French physicist Sadi Carnot determined the maximum efficiency of heat engines. The Carnot ...

For two centuries, students have learned that heat flows and engines work according to rigid limits that no machine can beat.

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 ...

The heat engine works as its intrinsic spin converts heat absorbed from laser beams into oscillations of a trapped ion. Credit: John Goold, Trinity College Dublin A new heat engine made from a ...

Physicists from Trinity College Dublin believe new insights into the behavior of light may offer a new means of solving one ...

Researchers who are studying a new magnetic effect that converts heat to electricity have discovered how to amplify it a thousand times over -- a first step in making the technology more practical.

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 ...
