One famous limit of thermodynamics is that heat engines, like steam engines and internal combustion engines, must be less efficient than a Carnot heat engine (a heat engine cycle designed by French ...

Research from The University of Manchester has thrown new light on the use of miniaturised 'heat engines' that could one day help power nanoscale machines like quantum computers. Heat engines are ...

Scientists are working on a heat engine that consists of just a single ion. Such a nano-heat engine could be far more efficient than, for example, a car engine or a coal-fired power plant. Scientists ...

Power boost: a quantum heat engine in synthetic diamond. (Courtesy: Jonas Becker) Physicists have in recent years built a number of microscopic heat engines to investigate how the laws of ...
