Abstract:
An energy conversion system for use under the static head pressure of large bodies of water to convert the force of the head pressure into usable electrical energy comprising:a first cylinder with a first working chamber located between a first piston and a top section of the first cylinder, a second cylinder with a second working chamber located between a second piston and a top section of the second cylinder, wherein said second cylinder and second piston are of a predetermined diameter size larger than said first cylinder and said first piston, and a bottom section of said first cylinder is connected to a bottom section of said second cylinder via a hydraulic link; and a valve to open and close fluid communication between said first working chamber and a large body of water, a first pump for evacuation of said first chamber when said valve is closed, a heat exchanger in communication with said second working chamber for transfer heat from a trapped gas inside said second working chamber to a fluid inside said heat exchanger; a second pump for circulating said fluid through a turbine and said heat exchanger, an electrical generator connected to said turbine.
