Abstract
Abstract This disclosure is directed to a differential temperature fluid motor having a warm chamber containing a small supply of activating fluid connected in communication with a cold chamber adapted for cooling the activating fluid and for obtaining a mechanical advantage from a small supply of rising activating fluid. By utilizing a temperature differential between the cold and warm chambers to obtain a vapor pressure differential, a flow of activating fluid is cycled to and from the two chambers for concentration of buoyant force and imparting relative movement in the cold chamber and translation of said movement into useful work.
