The present invention is a magnetic turbine, comprising, a housing, a set of blades attached to the housing, a set of magnets attached to the housing, a shaft connected to the housing, a based, wherein the base contains a system to convert rotational energy into electrical energy, a magnetic propulsion system connected to the base, and positioned relative to the set of magnets.

A wind turbine is described which includes a support structure, a rotor which includes one or multiple rotor blades and which is situated on the support structure so that the rotor is freely rotatable about a rotation axis, and a generator which is connected to the rotor and which converts the wind energy into electrical energy when the rotor is rotating. The support structure includes a stationary ring on which the rotor is rotatably guided and on which the stator of the generator is situated.

An adapter element for a solenoid valve assembly in an irrigation system includes an integral water turbine generator including an impeller positioned in an outlet flow path of a solenoid assembly thereof such that the impeller rotates when water flows to generate electricity.

A wind harvesting assembly for a wind turbine, having: a Venturi tube having a hollow interior having a first air pressure; an open top end having a first diameter; an open bottom end having the first diameter; a tube length spanning between the open top end and the open bottom end; and a constricted section located above the bottom end, the constricted section adapted to increase a velocity of air passing through by having a second diameter smaller than the first diameter; a plurality of vertical wind turbine blades arranged around the Venturi tube, an outlet disbursement blade assembly disposed below the bottom open end of the Venturi tube and a port fan positioned coaxially with the Venturi tube.

A kinetic modular machine for producing electricity from flows, either mono or bi-directional, moving at different speeds, includes one or more turbines that are “open center” and coaxial; a floating/positioning system; and a connection between the kinetic modular machine and a docking. Each turbine has a rotor, a stator, and a synchronous generator. In different configurations, the turbines are structurally, mechanically and electrically independent. The floating/positioning system includes a floater, a wing, and a fixture linking the turbines to the floater, implementing the control of the rotational axes (roll, pitch, yaw), with the wing keeping the machine at a given distance from the shore and the fluid surface. The modular design, having independent turbines, allows for a flexible design, keeping the installation and maintenance costs low.

A generator for a wind turbine comprising a generator stator having a mounting portion for fixing the generator stator to a machine carrier of the wind turbine, and a generator rotor mounted rotatably about a generator axis relative to the generator stator. The generator has a single-stage transmission which is adapted to non-rotatably cooperate at the drive side with a rotor blade hub and which is non-rotatably connected at the driven side to the generator rotor.

A turbine having a rotor assembly with substantially cylindrical blades. A scoop may be used to direct a fluid flow into the turbine, thereby causing a pushing force and/or a suction force to be exerted on at least some of the cylindrical blades. Accordingly, the rotor assembly may rotate within the turbine. In an example, the rotor assembly may include a plurality of magnets, which may cause a magnetic field to fluctuate. Copper discs on the turbine enclosure may be used to generate electricity based on the changing magnetic field. In another example, the turbine enclosure may have one or more openings, which may generate a suction or pressure force as the rotor assembly rotates.

A wind harvesting assembly for a wind turbine, having: a Venturi tube having a hollow interior having a first air pressure; an open top end having a first diameter; an open bottom end having the first diameter; a tube length spanning between the open top end and the open bottom end; and a constricted section located above the bottom end, the constricted section adapted to increase a velocity of air passing through by having a second diameter smaller than the first diameter; a plurality of vertical wind turbine blades arranged around the Venturi tube, wherein each vertical blade of the plurality of vertical wind turbine blades is associated with permanent magnets.

A wind power generation apparatus mainly disposes a support axle inside a tower rack of a wind power generator, and an upper vertical axle blade and a lower vertical axle blade arranged upwardly and downwardly are at least pivotally jointed on the support axle disposed inside the tower rack. A windward opening is disposed at the position where a circumference wall of the tower rack corresponds to the upper and lower vertical axle blades, and the lateral wind could enter into the tower rack through the windward opening to cause tornado effect to push the upper and lower vertical axle blades to rotate and output dynamic force to connect the power generator and generate electricity.

Provided is a method for cooling an electric generator including the steps of: monitoring the temperature of the end winding and of the magnet through said first and second temperature sensors, if the temperatures of the end winding and/or of the magnet rises and reaches a first upper limit, operating the plurality of cooling fans for providing a first cooling power to the electric generator, if, while the first cooling power is provided, the temperature of the magnet reaches the second maximum acceptable temperature and the temperature of the end winding is lower than the first maximum acceptable temperature, operating the plurality of cooling fans for providing a second cooling power to the electric generator, the second cooling power being lower than the first cooling power.
