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 ...

It is argued that the Carnot cycle is a highly inaccurate representation of a steam engine, and that the net work obtained in its operation would be zero. This conclusion is also supported by an ...

THE Carnot cycle in Dr: G. W. Todd's interesting letter (NATURE, March 1, p. 5) leads by a ready extension to the result that if the force of gravitation on a body depended on its temperature, and ...
