ABSTRACT:
An apparatus for producing useful energy from the potential energy stored in a deep body of water using tidal and/or wave forces. A hollow base supported above the sea bottom slidably receives a piston therein. A first cylinder is rigidly attached at its lower end to the piston and at its upper end to a floating structure so that the floating structure and piston move vertically in response to wave and/or tidal action and which can be fixed at any position therealong by locking pins. The base is provided with one-way valves on its upper and lower end that only allow water to exit the base through the valves. Water enters the base through a one-way valve in the first cylinder and a tube in the first cylinder. A turbine positioned in the tube is driven by the water as it travels through the tube. The turbine drives a power generator. A second cylinder in the tube that extends above the upper end of the floating structure provides for air flow into and out of the base to prevent vacuum resistance to movement of the piston and to refill with air base chambers purged of water.
