Abstract

The invention is a method and apparatus for extracting power from a buoyant source within a contained column of liquid. It is comprised of an endless chain of movable buoyant objects, a means to convert the movement of the chain into useful work and a tank filled with a constant volume column of water. The buoyant objects comprising the chain sequentially enter the bottom of the water column, move up through the column and emerge at the surface. The emerging buoyant objects leave the tank and are directed to the tank bottom were each buoyant object repeats the cycle. As the chain of buoyant objects cycle through the water column, the volume of water remains constant, with one buoyant object of the chain entering the bottom of the water column as one is exiting at the top surface. The movement of the chain is a function of the buoyancy of the buoyant objects and the movement is converted to work by any conventional means using a rotary drive or linear escapement motor.
