Vertical gravity/buoyancy power generator

The vertical gravity/buoyancy power generator relates to the generation of power by harnessing the gravitational and buoyant forces which act on an apparatus in a natural or man-made liquid medium and convert such forces into mechanical energy. More specifically, the vertical gravity/buoyancy power generator improves on operably different, fluid medium power generators by efficiently utilizing the gravitational force as efficiently as the buoyant force is harnessed. The vertical gravity/buoyancy power generator includes methods, systems and devices for a plurality of weighted containers which ascend and descend in a primarily vertical plane and which drive one or more chains, belts or conveyances with rotating sprockets or pulleys on horizontally aligned shafts in primarily a vertical arrangement upon such apparatus. In the descent phase the containers are open on both ends (FIG. 1) and have greater density than the volume of liquid they displace causing them to rapidly descend through the liquid medium due to the gravitational force. In the ascent phase the containers are filled by bladders (FIG. 5), have both ends closed, or are closed on their upper end when, in any embodiment, a volume of gas is introduced such that the overall volume of the containers have a lesser density than the liquid displaced causing the containers to rise through the liquid medium due to the buoyant force. The chains, belts or conveyances driven by the containers rotate the sprockets or pulleys (FIG. 1) and their associated shafts creating mechanical power. Such power can be used to turn electrical generators or other mechanical machines which necessitate such power input.
