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 ...

A study published in Physical Review Letters (PRL) details a "Gambling Carnot Engine" that researchers report can attain 100% efficiency while also improving power generation. The researchers present ...

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 ...

When French engineer Sadi Carnot calculated the maximum efficiency of a heat engine in 1824, he had no idea what heat was. In those days, physicists thought heat was a fluid called caloric. But Carnot ...

IN a paper on Carnot's Cycle and the Efficiency of Heat Engines, reported in NATURE, August 29, Dr. J. S. Haldane comes to the astonishing conclusion that “the Carnot cycle is radically in efficient” ...

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 ...

The most comprehensive sci-tech news coverage on the web ...

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 ...

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” ...
