Abstract: A wind generator system with a plurality of lightweight, surface area adjustable airfoil/sail blades. Each blade is triangular or wedge shape with a narrow inner edge and a wide outer edge. Each blade includes an inner frame connected to a rigid mast that extends radially from a hub assembly. Each blade includes a curved outer skin layer that extends over the inner frame and configured into air foil shape with a large curved leading edge and a thin trailing edge. The outer skin layer is secured along its leading edge and removeably attached along its trailing edge to the inner frame. Coupled to the outer skin layer is a first linear actuator that when activated, causes the outer skin layer to fold or unfold thereby changing the blade's surface area. The internal frame may include a second linear actuator and a telescopic mast over which the blade slides to increase or decrease the sweep area of the blades.

Abstract: A wind generator hub assembly with lightweight, high efficiency, hybrid airfoil/sail blades. The hub includes three to eight blade mounting surfaces each with a radially extending blade attached thereto. The blades are identical and wedge-shaped and evenly distributed radially around the hub. Gaps are created between each blade. Each blade has an airfoil profile with a curved outer skin layer. Each blade has a large curved leading edge and a flat trailing edge similar to an airfoil. The outer skin layer is secured along its leading edge and removeably attached along its trailing edge to a lightweight internal frame. Each blade includes a transversely aligned end cap with optional louvers. The blades are oriented so their outer skin layers face downwind and rotate towards their leading edges. When wind flows against the inside surface of the skin layers, the blades act as sails to produce thrust.

Abstract: A portable, non-fossil fuel, multiple source, electrical power unit that includes a lightweight wind generator assembly and an optional solar panel assembly partially disassembled and stored in a rigid, protecting container. The power unit includes a pivoting tower assembly made of a plurality of tower members that are removed and assembled in an end to end manner to form an elongated tower assembly. A nacelle and wind generator are attached to the distal end of the tower assembly. The wind generator is attached to a lightweight hub assembly that uses lightweight sail/airfoil shaped blades. In one embodiment, the container includes four pivoting outrigger legs. In a second embodiment, the container's four side panels fold downward. Concrete blocks may be used to hold the container upright. Mounted on the container is a solar panel assembly with at least one solar panel and a bank of rechargeable batteries.

Abstract: A low wind, lightweight horizontal axis wind generator with two adjustable rotor assemblies that include at least one set of lightweight blades that can be manually or automatically unfurled or furled in low, moderate and high winds. In one embodiment, each blade has an airfoil shape in cross-sectional with a rounded leading edge and a thin tailing edge. In a second embodiment, each blade is sail shaped made of one thin cover or panel that assumes a concave cup-like configuration in the wind. In both embodiments, the blade are made of lightweight flexible material supported by an inner frame. In one embodiment, the cover moves longitudinally over the inner frame. In the second embodiment, the cover moves laterally over the inner frame. The unfurling and furl of the blades are controlled by a voltage sensor that constantly measures the voltage output of the generator and/or by wind sensors.

Abstract: An apparatus and method for generating electricity from relatively low velocity exhaust gas. The apparatus includes a plurality of axial flux generators perpendicularly mounted on a support ring that is axially aligned around the exhaust gas port opening. Each axial flux generator includes a plurality of radially aligned blades mounted on a rotating hub. The hub is mounted on a stationary axle supported above the support ring by brackets. Attached to the hub are two magnetic discs each with a plurality of magnets attached thereto. Located on the outside surface of each magnet disc is a flux disc that produces an inward force to hold the two magnet discs together. Mounted on the axle and located between the two magnetic discs is a fixed stator disc that includes three internal coil systems. When the exhaust gas moves through the exhaust port it interacts with the blades causing the two magnetic discs to rotate around the stator disc and thereby induces an electric current inside each coil system.

Abstract: A wind generator that includes a lightweight, collapsible blade assembly mounted on a supporting structure that holds the blade assembly in fixed position that is exposed to low to moderate winds. The blade assembly is coupled to the distal end of a drive shaft linked to a low RPM, axial magnetic generator designed to produce A.C. electric current when rotated at low speeds. The blade assembly is a cylindrical structure with a longitudinally axis. Coaxially aligned around the longitudinal axis is an outer blade component and an inner blade component. The outer blade component is a non-rotating structure which includes a plurality of directional blades designed to direct the wind into and towards the blades on the inner blade assembly. The inner blade component is designed to rotate inside the outer blade component and coupled to the generator's drive shaft.

Abstract: A variable volume and velocity water electric generator system for use in a narrow channel in which variable amounts of water flow. The system includes an electric generator/water wheel unit mounted on a rigid frame vertically aligned within the channel. The unit includes an electric generator and the water wheel assembly that are axially aligned. When the frame is vertically aligned and lowered into the channel, the water wheel assembly is transversely aligned in the channel and its fixed vanes optimally positioned into the path of the water flowing through the channel. The generator's outer casing is connected to an end plate on the water wheel assembly so that the outer casing and the water wheel assembly rotates as one unit. A programmable inverter is connected to the generator that measures the voltage output and controls the amperage load exerted on the electric generator to electrical power extracted from the water is optimized.
