    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: The invention relates to a system that includes a wave energy converter and an assembly, adapted to be driven by the wave energy converter. The wave energy converter includes an array, in the form of rows and columns, of floating elements adapted to float on a sea surface in the vicinity of a shore. Each floating element has a first and a second end, each end being connected to a lever, the lever being connected through a bearing to a pivot point. Each lever is connected in an articulated manner to a piston rod in a wave-actuated liquid pump, that is in fluid communication with the pipe, adapted to lead a liquid to a workstation, wherein the workstation includes the assembly.

    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: 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.

    Abstract: A wave-actuated power generating apparatus comprising an impulse-type water turbine mounted for rotation on an upright output shaft within a housing. The housing includes a back panel and opposing sides and upper and lower surfaces which form an inlet water nozzle. The water nozzle is oriented to face oncoming waves and to direct them into the housing. A wave splitter directs a portion of each oncoming wave directly against the facing surfaces of the water turbine blades, while another wave portion is directed first against the back panel of the housing and, thereafter, against the facing surfaces of the blades. Each wave portion is redirected arcuately forwardly through about 180 degrees inwardly toward the central portion of the housing causing the water turbine to rotate. Thereafter, the water within each wave entering the housing is discharged downwardly through a water outlet positioned in the housing lower surface behind the wave splitter. By this arrangement of wave splitting, a more uniform and extended wave pulse per wave for rotating the water turbine to produce power is effected.

    Abstract: A wave operated power plant is provided wherein a buoyant vessel is anchored on the ocean surface with the wave motion causing displacement of water carried in a chamber in the hull such that upon rocking motion the water is forced upwardly through pipes on one side of the vessel. The water contacts turbine blades which through shafts rotate electrical generators and generate electricity. The water is returned to the chamber when the vessel moves in the opposite direction and the cycle is repeated with water forced up through pipes in the other side of the vessel, used for electrical generation and then returned to the chamber. The water being forced up from the chamber can contact the blades directly or be stored in a tank on top of the vessel and released at a predetermined rate.
