A fluid dynamic kinetic energy-based frictionless type generator of a range extender and recharger for an electric vehicle or device and the production of electricity is characterized by converting fluid motion into electric energy. This device uses the drag force acting opposite to the relative motion of objects moving with respect to a surrounding fluid. This force can exist between two fluid layers or a fluid and a solid surface. The device comprises a cylinder covered with paddles, air ducting ramp, permanent magnets, armature winding, charge controller and battery bank. It's a frictionless, high efficiency, brushless generator design that utilizes kinetic energy produced by drag, pressure, friction, fluid resistance, fluid dynamics, aerodynamics, wind, and or motion together with the device itself to create a frictionless brushless generator that will deliver power to the engine directly, the enclosed battery bank or can be diverted to the vehicle battery bank for recharging.

A synchronous generator, in particular a multiple-pole synchronous ring generator of a gearless wind turbine, for generating electric current, comprising a rotor and a stator is provided. The stator has a large number of slots for receiving a stator winding in the form of conductor bundles, wherein the slots each have a slot base, whose surface is profiled in such a way that, during filling, a first layer on the slot base side of conductor bundles assumes an orientation which is preset by the profile. A stator for such a generator and to a wind turbine comprising such a generator is provided.

A wind turbine device includes a rotatable seat, and a blade assembly including a rotary shaft having a fulcrum portion rotatably connected to the rotatable seat, and two mounting portions extending oppositely and respectively from two opposite ends of the fulcrum portion. At least two blade units are respectively connected to the mounting portions. Each blade unit includes a plurality of angularly spaced-apart blade modules each including a grid frame and a plurality of blades connected to the grid frame. The grid frame includes at least two airfoil-shaped first rods extending along an axial direction of the rotary shaft and spaced apart from each other along a radial direction of the rotary shaft.

A cycloidal rotor is provided having a flexible by actuators or self-flexing blade-positioning tack, which can be brought into shape corresponding to currently desired blade orbit. This rotor can also be provided with frontal shielding or partial enclosure to assure that rotor operates at any speed as if in hovering flight; rotor track can be inclined to produce forward thrust or external thrusters can be used. Optionally in other embodiments blade orbit shape is determined by a variable cam mechanism or the inclination of blade positioning track of fixed shape to produce a change of its projected shape onto blades' plane of operation thus changing blades elliptic orbit. Blade centrifugal force countervailing mechanism is also proposed.

The present invention is a wind direction system. The system includes at least one lower airfoil having a leading edge, front surface, middle surface, rear surface, and trailing edge, and at least one wind turbine mounted above the at least one lower airfoil. The lower airfoil is mounted to a building surface. The front surface of the lower airfoil is angled into an airflow relative to the middle surface. The lower airfoil causes wind airflow traveling over a building to be drawn to an upper surface of the building and be directed towards the wind turbine, resulting greater utilization of the wind and increased power generation through the turbine.

An embodiment of Horizontal and Vertical Axis Wind Generator (HVAWG) concept with rotating big and small wings, magnetic coils, and magnetic field magnets attached to the wings. The generator motors use the generator motor coils, the generator motor magnets, magnetic field coils and magnetic field magnets to help produce the power using the repulsive characters of the same magnetic poles. Also, both the outside and the inside parts of the generator motors rotate while the inside parts of the generator motors rotate in the traditional wind generators.

Air powered electrical generator (APEG) motive parts are mounted on an axle carrying bilateral air turbines and two intermediate rotor subassemblies. Circular rotor blade plates have scalene triangularly shaped cavities with long leading edge sides receiving compressed air flow, short trailing edge sides and an open peripheral air portal. Adjacently mounted blades are offset such that one air portal then another air portal is presented to compressed air flow from nozzles during rotation. Each turbine shroud has a manifold feeding compressed air to the nozzle, as a venturi, due alternating presented air portals. Each rotor carries permanent magnets on its radially outboard segments. Bilateral stationary stators are transversely fixedly mounted outboard of the rotating rotor subassemblies. Electrical outputs carry power from the stators when the rotor subassemblies rotate.

A power generation system includes a flotation assembly configured to float in water and a first harnessing assembly coupled to the flotation assembly and disposed in an airflow above the water. The first harnessing assembly is configured to harness the airflow to create a first rotational energy. The system also includes a second harnessing assembly coupled to the flotation assembly and disposed in the water. The second rotational assembly is configured to harness movement of the water to create a second rotational energy. The flotation assembly also includes a generating module to convert the first and second rotational energies into electrical energy.

A rotor for power driving includes a hub, a plurality of first fixed jibs, a plurality of second fixed jibs, and a plurality of outer vanes. The hub is adapted to be coupled with a shaft to rotate together in a single rotational direction. The first fixed jibs are arranged around the hub circumferentially. Each second fixed jib is engaged on an end of a corresponding first fixed jib. Each outer vane is elastically fixed at a corresponding second fixed jib and extends in a direction different from the single rotation direction when not acted upon by external forces such that the plurality of outer vanes, when acted upon by external forces, are elastically movable relative to corresponding second fixed jibs to drive the shaft to rotate along the single rotational direction and can rebound after removal of the external forces.
