Abstract: A rotational power transfer device includes a rotatable shaft, a plurality of arm structures attached to the shaft and extending radially outward from the shaft, a plurality of pin structures attached to and extending radially outward from the shaft such that the arm structures and the pin structures are aligned, a plurality of panel members attached to the arm structures and hanging downward therefrom, and an energy converting member for converting energy to electricity.

Abstract: An omni-directional, vertical-axis wind turbine which includes a rotor/stator combination which maximizes energy production by increasing wind velocity and pressure plus eliminating back pressure. The stator section includes a plurality of vortical blades secured between upper and lower conical sails. The blades have a radius fundamentally equal to that of the rotor and a chord length approximately 1.25 times its radius. The rotor has a diameter approximately equal to one-half that of the stator and has a plurality of concave blades secured to and spaced from a vertical spindle, said blades being arranged in stages within the vertical rise of the rotor. Each rotor blade has a chord line equal to twice its radii and a chord length approximating one-third the diameter of the stator.

Abstract: A windmill for efficiently catching wind for turning an axle. The windmill includes a support structure. The support structure includes a plurality of generally vertically orientated posts. Each of the posts is spaced from each other. Each of the posts has a top edge. A covering is positioned on and is securely coupled to each of the top edge of the posts. A first axle is elongate and has a first end rotatably coupled to a bottom surface of the covering. The first axle has an upper portion and a lower portion. Each of a plurality of vanes is comprised of a top arm, a bottom arm and an end portion. Each of the arms has a first end securely attached to the upper portion of the first axle and a second end securely attached to an opposite end of the end portion such that a frame is defined. Each of a plurality of panels is substantially rigid and has a front side, a back side, a top edge, a bottom edge, a first side edge and a second side edge.

Abstract: System for harnessing wind energy with self-protection that includes a vertical shaft (1) assembled with bearings on the rotating core (3) equipped with a gear (4) converting movement into energy, carrying radial pieces (5) in which there is an upper base (6) that supports the ascending vertical shaft (7) terminating in a discoid piece (8), with the radial pieces (5) carrying internal shafts with bevel gears (11), connected to the bevel gears (12) assembled on the vertical shafts (13) mounted on the blocks (14) at the ends of the arms (5), with the shafts (13) carrying ball joints (15), from which the extensions of the ascending shaft (16) leave provided with a crossbar (17) with pulleys (18) provided with ties (19) with elastic springs that fasten the double blades (20), with the ties (21) to the ascending shaft (16), making it possible for the blades (20) to become wound around it, which occurs when the assembly rotates in the opposite direction.

Abstract: A parabolic or part parabolic focusing device located in the ocean comprises wall sections which converge a parallel ocean wavefront to foci located in an air compression chamber located between the wall sections, thereby providing a wave amplification effect. An oscillating wave surface produces an oscillating air column inside the chamber to drive a self-rectifying turbine located in an outlet at the top of the chamber. The turbine comprises a rotor with radially oriented aerofoil shaped blades which are symmetrical in cross section about a transverse plane so that the turbine rotates in a single direction regardless of the oscillations in the air column. Several mechanisms to vary the pitch of the blades are also disclosed.

Abstract: A wind-powered drive shaft, the rotary force of which can be used for a variety of purposes, such as to drive a hydraulic pump, the crankshaft for a water pump, or an electrical generator. To a central shaft are attached two or more sets of arms extending radially outward from the central shaft and containing two or more arms each. Preferably the sets of arms are arranged in pairs about the central shaft. Each set of aims has two or more aims. Two or more pivot shaft are rotatably attached to each arm in a set of arms and between vertically adjacent arms a vane composed of light but strong material is connected to each pivot shaft. Attached to one of every two vertically adjacent arms is a stop, said stop being in such a location that the free end of the vane will contact said stop when such free end makes its closes approach to said central shaft.
