Heat is a byproduct of combustion. Both air-cooled and water-cooled engines need to dissipate that heat to keep the engine from running too hot. Can piston rings play a role in managing that heat?

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 ...
