  • [发明专利]US19770801180 _ THE UNITED STATES OF AMERICA AS REPRESENTED BY THE SECRETARY OF THE NAVY 1977年05月27日
    Ocean thermal energy conversion (OTEC) uses a fluid, such as ammonia, heated by high-temperature surface water to provide a turbine-driving working gas. To condense the gas for re-use, a slurry of phase-transformation particles and cold ambient sea wa...
  • [发明专利]US19770803543 _ HAGEN, ALF R. HAGEN, ERIC C. 1977年06月06日
    A combination floating breakwater and wave energy collecting system in which a pair of joint floating spread wings are provided between which a vessel can be moored. The spread angle of the wings is adjustable and the wings can be jointly swung about ...
  • [发明专利]US19770825142 _ KIKUT, EDMUNDO 1977年08月16日
    An apparatus is provided for extracting energy from the motion of water waves during both the ebb and flow of such waves. The apparatus includes a screw propeller which is disposed to contact the waves and to be driven thereby in opposite directions d...
  • [发明专利]US19770761740 _ PINNEY, PAUL E. 1977年01月24日
    An apparatus for the conversion of complex surface motion of the sea or other fluid body into useful energy, comprising a pair of floating bodies, each of which constitutes a wave motion pump; the pair of floating bodies being linked by a lever whose ...
  • [发明专利]US19770845781 _ FEDER, HUBERT C 1977年10月26日
    An arrangement of constructual elements used for the conversion of fluctuating natural energy and generation of constant rotary speed of a power-producing machine or motor, electric or otherwise, by way of free-falling masses in the place of commonly ...
  • [发明专利]US19770839190 _ COMPAIR CONSTRUCTION AND MINING LTD 1977年10月04日
    A reciprocating hydraulic motor, for example for a rotary percussive drilling head, includes a piston and cylinder having a piston face exposed to the pressure in a compression chamber which is connected through ports controlled by the piston to a sup...
  • [发明专利]US19770854148 _ MARKLEY D FELL 1977年11月23日
    In the embodiments shown, the device comprises a turbine wheel, rotatively journaled, having a peripheral, grooved surface onto which rounds of shot are impelled, under steam pressure, to rotate the wheel so that torque power might be derived therefro...
  • [发明专利]US19770816462 _ GARZA, ROBERTO M. 1977年07月18日
    A hydroelectric plant operated by wave action is supported by the ocean floor and extends above the surface of the ocean. Connected to an outer edge of the plant structure above the surface of the ocean is a plurality of pivotally connected lever arms...
  • [发明专利]US19770820840 _ COMPTON, ELMER 1977年08月01日
    A vapor or thermal engine which converts heat energy to mechanical energy. A rotor has a main shaft which supports a plurality of vapor chambers communicating with a condenser across appropriate check valves and rotary valves to form a closed loop sys...
  • [发明专利]US19770850974 _ LEE, ROBERT E. 1977年11月14日
    This invention relates to space vehicle where solar energy is used to generate steam, which in turn, propels the vehicle in space. A copper boiler is provided and a novel solar radiation condensing means is used to focus the sunlight on said boiler. S...
