Peter W. Ullman has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • 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.
