Abstract
A power-producing device, comprising a vertically oriented chamber of enormous height, incorporating within its upper end an electric motor-driven, aftercooled air compressor, being connected via suitable power transmission, to an electric generator driving, reheated air turbine, located within the lower chamber end. Atmospheric air is compressed at a given rate of flow to a given pressure into the upper chamber end, which, due to the gravitational force exerted on its compressed mass, and due to the chamber height, is expanded within the turbine at the lower chamber end at an equal rate of flow, but, at a substantially higher pressure, and at a substantial gain in energy, thus, producing a substantially greater amount of work than is consumed by the compressor.
