  • Apparatus for converting and storing wave energy
    Patent number: 4776772
    Abstract: An apparatus converts the naturally occurring energy potential found in waves into a pressurized water source. The apparatus, which can be positioned in a breakwater, is comprised of a float to track the crest and trough of waves, a pump, and mechanics to drive the pump in response to the vertical movement of the float.

  • Buoyancy prime mover with pressure control means
    Patent number: 4498294
    Abstract: A buoyancy prime mover that converts the potential energy of a gas buoyant within a liquid into rotating mechanical energy comprises a plurality of rigid or collapsible buckets joined by one or more chains with rotatable sprockets and shafts to form a continuous loop within an enclosure and means for controlling the pressure within the enclosure whereby the buoyant gas is trapped within the buckets, the buckets rise through the liquid and rotate the chain and sprockets to generate power.
