Patents by Inventor Greg Greenspan

Greg Greenspan 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).

  • Wave energy recovery system
    Patent number: 7683500
    Abstract: A novel apparatus and methods for recovering energy from water waves is provided. An embodiment of the present invention includes a buoy, a shaft, and an electric power generating device. The shaft is coupled to the buoy such that when the buoy moves vertically in response to a passing wave, the shaft rotates. The shaft is coupled to the electric power generating device such that when the shaft rotates, the generating device produces electric power. Once electric power is generated, it is delivered to shore, where it is stored, used to power a device, or delivered to a power distribution grid.
    Type: Grant

  • Wave energy recovery system
    Patent number: 7474013
    Abstract: A wave energy recovery system includes a plurality of motion translating assemblies, each assembly includes a buoy coupled to a shaft segment. The shaft segments form a shaft that is coupled to an electric power generating device. Each shaft segment is coupled to a buoy such that when the buoy moves vertically in response to a passing wave, the shaft segment rotates, thus rotating the shaft. The shaft is coupled to the electric power generating device such that when the shaft rotates, the generating device produces electric power. Once electric power is generated, it is delivered to shore, where it is stored, used to power a device, or delivered to a power distribution grid.
