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

A 200-year physics rule fails at atomic scales, researchers say
For two centuries, students have learned that heat flows and engines work according to rigid limits that no machine can beat.
Designing a heat engine that can produce maximum power at maximum efficiency is a major challenge. Practical heat engines are limited to a theoretical efficiency called the Carnot limit, which sets a ...
Physicists have designed a novel micro heat engine that can produce maximum power at maximum efficiency 1. The engine operates with a single particle whose width is one hundredth of a single human ...
