Scientists develop a microscopic heat engine that achieves 100% efficiency, accomplishing what seemed impossible.

In 1824, French engineer Nicolas Leonard Sadi Carnot – known as the father of thermodynamics – proposed what is known as the Carnot engine, the most efficient engine which is theoretically possible.

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 ...

In 1813, Napoleon's failed campaign against Russia led to a coup d'état in Paris, France. Prussia and Austria then invaded France. Among the troops guarding Paris at the time was Sadie Carnot.

ON p. 326 of NATURE for August 29 appears an abstract of a paper by Dr. J. S. Haldane, which he read before the Institution of Mining Engineers on June 16. In this paper he has “thrown to the winds” ...

Researchers at the Indian Institute of Science (IISc.) and Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) have cracked an age-old thermodynamic puzzle by devising a novel micro heat ...

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 ...
