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 ...

Researchers at MIT have built a highly efficient thermophotovoltaic cell that, when paired with renewable resources, efficiently converts incoming photons—particles of light—to electricity. It’s an ...

(Auburn, AL) Heat has always been something we thought we understood. From baking bread to running engines, the idea seemed simple: heat spreads out smoothly, like water soaking through a sponge. That ...
