Ultrasmall engines bend second law of thermodynamics
Quantum entanglement may help single atoms drive heat machines
THE LAWS OF HEAT GO SMALL Car engines and batteries run because of the second law of thermodynamics, which appears to work, with just a little bending, for ultrasmall engines in the quantum realm as well.

When French engineer Sadi Carnot calculated the maximum efficiency of a heat engine in 1824, he had no idea what heat was.
