An energy output device that harnesses the buoyant effect produced as air rises through a plurality of finned cylinder wheels submerged in a volume of water. The finned cylinder wheels are positioned along a vertical axis above the point at which air enters into the water. The finned cylinder wheels contain a set of fins that trap the rising air so that the buoyant effect created combined with fluid gravitational farce causes the finned cylinder wheels to rotate. A plurality of intermediary gear assemblies are alternately positioned with the finned cylinder wheels linking the vertically aligned components together. The simultaneous rotation is ultimately transferred to a torque output axle gear assembly located above the alternating finned cylinder wheels and intermediary gear assemblies.
