Abstract:
1. A power generator, comprising: a) a body of water having a top level that fluctuates, the body of water is contained within a harborage that is subject to tidal activity, the harborage having a port therein so as to allow water to flow in and out of the harborage, the port having a valve that can regulate the flow of water through the port; b) a vessel hull buoyantly located on the water body, the vessel having a displacement of at least 3000 tons, the hull being free to move vertically as the top level fluctuates due to tidal activity; c) a piston-cylinder arrangement coupled between the vessel hull and a fixed object, the cylinder having an output for pressurized fluid when the vessel moves vertically, the piston-cylinder arrangement constraining horizontal movement of the vessel hull; d) a turbine having an input which is connected to the cylinder output, wherein pressurized fluid from the cylinder rotates the turbine.
