[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)
