  • Method and apparatus for deriving useful energy from sea waves
    Patent number: 4078382
    Abstract: A sea wave powered electrical generating apparatus includes converging dams 9 to funnel and amplify wave energy, a pressure chamber 8 having an entrance/exit gate 11 and a turbine rotor disposed on a vertical axis above the pressure chamber. The arcuate zig-zag configuration of the turbine blades coupled with windows 3 at the tops and bottoms of the blades results in a double action mode of continuous rotation as the wave surges pass up through and back down through the rotor.
