A wave power generator includes a frame unit mounted on the shore, an electric generator unit generating electricity by means of a rotating motion of a rotor, a drive unit having a plurality of wave-power receiving bodies receiving the energy of a reciprocating horizontal motion of wave power and reciprocating between the sea-side and the land-side, wherein the wave-power receiving bodies are mounted in the frame unit in a stepwise manner in a plan view so that the wave-power receiving bodies do not meet the waves at the same time, and a power transmission unit mounted in the frame unit to convert a linear motion of the drive unit into a rotating motion and transmit the rotating motion to the rotor of the generator unit.
Abstract:
A method for generating electrical current indirectly from ocean wave action based on the reciprocating surge of the ocean that directly results from the overhead wave action. The method includes (a) positioning an energy transducer below overhead wave action and at a depth and orientation substantially responsive to reciprocating water surges arising from the overhead wave action; and (b) powering the energy transducer by the surges in alternating first and second directions to generate electrical current.

Abstract:
Several embodiments of a device for economically harvesting wave energy are disclosed. A sealed vessel for air storage, the spar buoy, is mostly submerged under water is also used as an inertial body that surface floats move relative to. The spar buoy may take many geometrical forms, but all have a stem that is above the water surface. Piston pumps are placed at the top of the stem. The pump has a gearing reduction to optimize the rotational motion of the pump drive shaft. Small angular motion at the drive shaft results in multiple cycles of linear reciprocal motion of the piston. Various mechanisms could convert the relative motion between the floats and the spar buoy to a rotational motion of the shaft. The compressed air generated by the pump is stored in the spar buoy and regenerated as electrical energy by expanding the compressed air in a turbine.
Abstract:
A wave energy converter (1) consisting of a pole (2) with a wave catching structure (9) connected to a base (7) through a ball or universal joint (6). The pole oscillates as the waves hit the different sides of the wave catching structure. The pole is biased towards the vertical position. The motion of the pole activates devices for absorption and extraction of energy such as piston cylinders (3) with one end attached to the pole and the other to the base (7) by ball or universal joints (4) and (5), which also restrict the motion of the pole along specific meridians by use of appropriate hydraulic components. The possibility of motion of the wave catching structure along the pole increases the absorption of wave energy. Being able to exploit waves from any direction and also to assume a floating form, it is suitable for both deep and shallow waters.

Abstract:
An improved design for turbines increases efficiency while reducing potential for fish kill. In an embodiment of the present invention as relates to Kaplan turbines, the gap between stay vanes and their corresponding wicket gates is reduced or eliminated by provision of an extension to the trailing edge of the stay vane. In alternative embodiments, the extension may be added to the wicket gate or affixed to both in an arrangement that permits free movement of the wicket gate. To facilitate eliminating the gap altogether, the extension may be made of a pliable material or be fabricated in a telescoping or accordion arrangement to permit contact with opposing parts without damage thereto. By designing extensions using accepted hydraulic principles, a better fit of the stay vane to its associated wicket gate, and possibly to the turbines runners may be effected, further improving operational efficiency and possibly even extending maintenance intervals.
Abstract:
Portable power generating devices are provided for converting potential energy from flowing water, water current, blowing air or air current to mechanical and/or electrical energy. The potential energy is converted to a rotational movement, and the rotational energy is communicated to power conversion units for conversion, wherein the rotational movement is converted to mechanical, electrical or some other useable or useful energy.
