Abstract: A wave energy converter system comprises two floats; a first being generally flat and heaving up and down in phase with passing surface waves on a body of water, and the second being elongated and heaving up and down out of phase with the passing waves.

Abstract: A renewable energy power generating plant is disclosed. It uses the renewable energy of fluids according to Archmedes Principale. It includes a liquid-filled pool, an endless chain looping around lower and upper cogwheels, containers attached to chain links receiving compressed air in the bottom of the pool, gas under pressure from black smokers in the sea bottom, or highly compressed natural gas using only its excess pressure.

The weight of the liquid displaced by gas in ascending containers creates a steady torque on the axle of the upper cogwheel. The resultant rotation is transformed into an abundant source of energy adaptable to a wide range of applications.
