    摘要： A wave power plant is disclosed which has one or more foils that are pivotally movable about a body. The foil is set into an oscillating, pivotal motion about the body by the force of the waves. A power engine is mounted between the body and the foil and extract works as the foil pivots about the body. The foil and body are held submerged below the surface of the water to reduce the effects of extreme weather conditions on the structural components.

    摘要： A wind-powered turbine generation system configured to generate electric power over a wide range of wind conditions and particularly in high wind speed and wind gust conditions. A plurality of ducted turbines is provided in an enclosure rotatably mounted to a vertical support. Rows of magnetic irises surround the turbine shafts with each iris adjustable to throttle the airflow over the turbine blades, permitting the turbine generator to operate in high wind velocity gusts.

    摘要： A wind-operated power-generating module for operation at high altitudes such as 1000 meters comprising a frame structure mounting a pair of vertically-separated parallel shafts around which pass endless belts supporting a series of parallel, elongate wing-like elements for movement around a closed path including the parallel shafts. Wind flow drives these elements around the closed path, to enable electrical power to be generated, and also provides lift to hold the module up at the appropriate high altitude. A number of such modules are tethered in fixed positions in the sky, and are controllable as is appropriate to accommodate changing wind conditions.

    摘要： There is disclosed a method and apparatus for converting the kinetic energy of a moving fluid stream into useful work by means of a cascade of thin airfoils positioned therein. In one embodiment, the airfoils are provided with at least two degrees of freedom and adjacent airfoils are movable out of phase. The airfoils are subjected to the aerodynamically induced oscillations caused by the aeroelastic phenomenon known as flutter and the oscillatory movement is then harnessed to do useful work. In an alternate embodiment, a cascade of airfoils is mechanically oscillated within a moving fluid stream to increase the propulsion of the fluid. Where the fluid is a liquid, the cascade includes a plurality of hydrofoils.

    摘要： Diffuser-augmented wind turbines can include a first diffuser ring arranged to form a turbine rotor cowling, the diffuser being fixed to and rotatable with the turbine rotor about the horizontal axis of the wind turbine. The first diffuser ring may have one or more dynamic, aero-elastic, vortex entrainment devices attached to a trailing edge of the diffuser. The first diffuser ring may include one or more slot gaps arranged within its body, each slot gap creating a channel between the interior and exterior surfaces of the first diffuser ring. In some embodiments the diffuser may optionally further include one or more further diffuser rings, the one or more further diffuser rings being static rings (e.g. non-rotatable about the horizontal axis) or dynamic diffuser rings (e.g. rotatable around the horizontal axis).
