[edit] Gravity chimney based cycle

Does anyone know the name of the gravity based cycle used in things like solar chimneys, thunderstorms and very large airconditioning systems? The cycle heats a gas at a constant pressure, expands the gas in a tall chimney (i.e. hundreds of meters tall), cools at a constant pressure and compresses down another tall chimney. I read a paper on it years ago and I can't find any references to it now. njh 00:37, 28 January 2006 (UTC)

[edit] Entropy equation untrue!!

There is a severe failure in this article

The integral (integral( dQ/T))over a hole cycle is only zero if it is an ideal cycle but for any other cycle the so called Clausius inequality is true!! where the Integral is smaller or equal zero! —Preceding unsigned comment added by 83.27.25.158 (talk) 11:05, 8 January 2008 (UTC)
