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.

Thermoelectrics using nanostructures offers the potential of getting very close to the carnot limit of efficiency using very light weight systems for convert heat to electricity. Early versions of ...

THE cycle proposed by Dr. J. S. Haldane (NATURE, August 29, p. 326) as a standard of comparison for steam engine performance can be shown quite readily on a temperature-entropy chart, and thus be ...

“We’ve developed the world’s smallest steam engine, or to be more precise the smallest Stirling engine, and found that the machine really does perform work,” said Clemens Bechinger, a physicist at the ...

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 ...

One of the basic truths learned in college thermodynamics courses is that no heat-activated cycle can be devised that is more efficient than a Carnot cycle operating between the same temperature ...

Heat is animus. It was there at the birth of the universe, and its death will be the universe’s death. It is impossible to overstate its importance — both throughout human history and across modern ...

Engineers have reported on the development of a microscopic motor operating between two thermal baths, that is, a micro Carnot engine. In a recent study published in Nature Physics, ICFO researchers ...

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” ...
