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

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 ...

In and out: An illustration of the quantum engine as a piston, showing the piston compressed when the particles in the gas exist as bosonic molecules and expanded when they are individual fermionic ...

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

Tabletop experiments by Indian physicists have broken a barrier proposed 200 years ago by a legendary French engineer, Sadi Carnot, raising hopes of new high-efficiency heat engines hitherto ...

A team of scientists has built a heat engine out of a single atom. Heat engines, like steam engines or internal combustion engines, convert heat into motion. To create the minuscule engine, physicist ...

The smaller the better, and in a world of fast-developing technology, that’s called innovation. Just this month, a desk-sized turbine capable of powering a small town was announced to be under ...

Researchers have developed a steam engine that's only a few micrometers wide. It works - although it does sputter a bit. (Image Credit: Max Planck Society) Researchers at the Max Planck Institute have ...
