Abstract
Abstract An apparatus and method for obtaining energy is disclosed. The method includes heating a fluid in a liquid state by heat exchange with a heat source to generate a vapor of the fluid at a first elevation. The vapor of the fluid is caused to rise to a second elevation within an enclosed space and is condensed at the second elevation by heat exchange with a cold source. The liquid obtained by condensing the vapor is caused to fall from the second elevation and the energy of the falling liquid is converted to another form of energy, which is preferably electricity. The apparatus of the invention includes structure for vaporizing a liquid to form a vapor, a vapor tower for increasing the potential energy of the vapor by causing the vapor to rise along an upwardly-extending path. Structure is also provided for condensing the vapor by heat exchange with a cold source and recovering the increase in potential energy from the vapor, preferably in the form of electric power.
