The invention provides an energy collector which includes an electrostatic drive to increase the acceleration of a rotor to maximize the proportion of the time at which the collector is able to efficiently generate power.

The present invention is a vertical axis wind turbine contained in a housing designed to introduce turbulent flow to increase efficiency. One embodiment of the invention uses a three bladed propeller with deflectors mounted upstream of the propeller to increase the pressure on the trailing edge of the blades. In another embodiment, an electric generator is coupled to the vertical axis wind turbine to convert the kinetic energy of a moving fluid into electricity.

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 diffuser system for a vehicle comprises a diffuser component mounted on the vehicle in a position to receive airflow when the vehicle is in motion. Further, a turbine component is provided in or associated with the diffuser component. The turbine component is driven by the airflow when the vehicle is in motion.

A stationary power installation for conversion of wind airflow energy is proposed, including a cylindrical body having a top rim radially protruded from the body's walls. The rim includes a groove on its upper surface, guide rollers, support rollers peripherally mounted on the groove's bottom.

An embodiment of Horizontal and Vertical Axis Wind Generator (HVAWG) concept with the rotating big and small wings, the magnectic coils, magnetic field magnets attached to the wings, generator motor, generator motor coils and generator motor magnetics is described. The generator motors in the present invention use the generator motor coils, the generator motor magnets, magnetic filed coils and magnetic field magnets to amplify the power using the repulsive characters of the same magnetic poles. Also, both the outside and the inside parts of the generator motors rotate the present invention while the inside parts of the generator motors rotate in the traditional wind generators. These features allows for a number of improvements over the current state of the art including damage protection, scalability depending the application and the speed regulation ability to remain operational during high wind and low wind conditions. In addition, the invention described here is scalable for cars, boats, airplanes, motor cycles, camping cars, drones, homes, offices, and power plants. Finally, the material of the horizontal and vertical axis wind generator is aluminum which is lighter, is easier to be installed, is durable and is corrosion resistant.
