An energy-producing system comprising an axle configured to be driven by an electric vehicle's wheels when in motion. The axle supports a series of wind-catching cups contained within an aerodynamic housing configured to direct air to the cups while also increasing the air speed. During vehicle motion, the cups are acted upon by rushing air causing the rotation of the axle such that the rotation may be transferred into energy via a generator/alternator linked thereto. A series of similarly polarized magnets integrated on said cups and/or spacers and/or housing proximate thereto further maintain the axle in motion during short vehicle stops. The system extends the life of the batteries between charges as well the distance the vehicle can travel between charges. A power controller is configured to distribute power from said generator to an axle drive motor, vehicle drive motor and/or start-up battery pack.

The present invention is directed to an improved vertical-axis wind turbine rotor that provides a more constant shaft power output than similar turbine rotors of the prior art. In a preferred embodiment, it provides four tiers of blade sets, with each set disposed at a different elevation than each other set. Each blade set may be offset at an angle from adjacent blade sets. A partition plate may be disposed between adjacent blade sets. The partitions provide structural stability and enhanced rotor performance characteristics.

A vertical axis wind turbine with improved safety, production efficiency and greater functional wind speed range. A vertical axis wind turbine comprises turbine blades having geometric characteristics of a “yin yang” symbol when viewed from the top down. The turbine blades are configured to form a scoop portion for catching wind. The surface area of the scoop portion may be dynamically configured to accommodate power production in higher wind speed ranges by dynamically furling the blades to reduce the surface area of the scoop portion as RPM begins to exceed a safe limit. First and second permanent magnet rotor arrays are dynamically positioned above and below an array of stator coils to maximize power generation.

A fluid turbine has semi-spherical, hollow blades arrayed about a vertical axis, and a passive wildlife-deterrent system using ultraviolet coloration of the rotor blades. The turbine's blade shape reduces drag on a convex side and increases drag on a concave side. Part of the center of the array of rotor blades is open, allowing flow through the center of the array. The spherical form enhances fluid flow through the center of the array and results in rotational force on a downwind blade, and directs fresh air into bypass flow.

A passive magnetic bearing employs eddy currents in a copper core between neodymium annular magnets to support the copper core and an associated rotating shaft. The copper core has an annular flange that is coaxial with a hollow cylinder. The hollow cylinder supports a rotating shaft. An annular iron core is coaxial with and surrounds the annular flange. Annular neodymium magnets surround the upper and lower portions of the hollow cylinder. In some embodiments a touch-down bearing is made up of an upper and a lower bearing race that are spaced away from the upper surface and lower surface of the annular flange. The core rotates over the bearing race(s) until sufficient magnetic flux is generated to support the copper core and hence the shaft. Once spinning, a magnetic field is generated in the copper core.

An axial-flux generator for fluid turbines has a continuously variable generator that is constructed of a pair of rotors that move radially across a stator resulting in varying torque and varying power output. In one embodiment the rotors are normally held proximal to the center of a stator by spring tension. The stator is larger than the normally held position of the rotors. As the angular velocity of the rotors increases, the rotors move radially toward the perimeter of the stator, thus encountering a greater stator surface area providing increased torque, increased power generation and a higher-rated output speed when used with a fluid turbine.

The present device is a vertically oriented wind turbine blade having a rectangular simple curvilinear shaped blade, which includes a top edge, a bottom edge, an outer edge, an inner edge, an inner surface and an outer surface. The blade is curved using a series of bent section to approximate as airfoil shape from the inner edge to the outer edge (relative to the turbine center or hub).

A fluid and wind turbine system suitable for horizontal or vertical axis applications comprising (i) blades radially spaced around a rotational axis attached to a shaft by mounting formations so that the length axis of the mounting formations are substantially parallel to the width axis of the blades which mounting formations suspend the blades from the rotational axis creating a passageway allowing the air flow to pass through the turbine and impart a unidirectional rotational force to the shaft at all times the blades are exposed to the air flow on both the windward and leeward sides of the rotational axis (ii) an air flow director which shields the rotating blades from the air flow for a portion of their 360-degree rotation.

A blade for a vertical windmill includes an arcuate blade member having an interior surface and an exterior surface, the arcuate blade member including at least one aperture extending through the arcuate blade member; and at least one layer of flexible sheet material applied to the exterior or interior surface of the arcuate blade member, the at least one layer of flexible sheet material covering the at least one aperture in the arcuate blade member on the exterior or interior surface.
