  • Patent number: 5872406
    Abstract: The present invention relates to an electric power generator apparatus that generates electrical power from the tidal movements of a body of water by employing multiple energy producing systems. Those energy producing systems include: (1) a moveable tank system associated with hydraulic cylinders in which the upward and downward movements of the tank relative to the tide are used to generate electrical power; (2) an enclosure system in which the controlled inflow and outflow of water between the enclosure and the surrounding body of water is used to generate electrical power; (3) a bellows system in which the effects of the tidal movements are used to force water from the bellows tank through a generator thereby producing electrical power; and (4) a buoyant mass-actuated piston system in which the movement of floating objects (such as docked ships) relative to the tide is used to generate electrical power.
