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 ...

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 ...

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 ...

For two centuries, students have learned that heat flows and engines work according to rigid limits that no machine can beat.

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 ...

“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 ...
