A vertical shaft wind turbine that is superior in a rotational startability, even at a low wind speed, and is suited to a wind power generator that has high rotational torque. Each blade is an upper-and-lower-ends fixed type vertically long blade which is suitable for use as a wind turbine or a water turbine. The string length and thickness of an upper-and-lower-ends fixed type vertically long blade (8) that is fixed upper and lower ends to a vertical main shaft (7) gradually decrease from a main part (8) thereof to tips of the upper and lower inwardly curved inclined parts (8B, 8B), and a cross section of the main part (8A) is a lift type. A thickness of the cross-sectional shape is continuously and gradually thins from the main part (8) to the tips of the inwardly curved inclined parts (8B, 8B).

A vertical axis wind turbine system for generating electricity. The whole turbine and the generator is structured around a single pole in the center. The pole holds the whole system together and supports the entire system. The System includes a turbine and a generator assembly. It consists of multiple folded L-shaped rectangle blades, which are structured around an empty cylinder whose purpose is to force air to go around it and into the blades for better efficiency. The empty cylinder is attached to the pole in the center of the system. The blades are attached to a bearing that spins around the pole on the top end and attached to the rotor on the bottom end of the empty cylinder. Each blade is folded at an angle to reduce the drag of the returning blades without compromising the surface area of the going blades.

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.

An improved turbine over the old horizontal and vertical axis turbines because of its ability to capture several times the amount of wind. The basic design and process of this new machine can also work in the ocean at capturing ocean currents. Being Omni-directional (not having to turn into the wind) gives it one efficiency over the 3 bladed turbine. Another efficiency all embodiments have is its frictionless exponent. This quality helps save on wear and tear and maintenance cost. Most if not all past turbines have a static presents, being built in one basic wind capturing position. This new turbine is more dynamic because it can hide from wind damage and then open to capture more wind than its predecessors.

An energy collection system for capturing wind energy being exhausted from an air exhaust system. The energy collection system has a frame and a wind turbine. The wind turbine has a blade configured to rotate about a shaft. Air leaving the air exhaust system in a vertical direction causes the blade to rotate which is then converted by the wind turbine into electricity.

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.

A wind generator assembly for harnessing wind to charge batteries in electric vehicles and hybrid vehicles includes a housing that is mounted on a roof of a vehicle. The housing has a wind passage extending therethrough and wind passes through the wind passage when the vehicle is driven. A turbine is rotatably positioned in the housing. The turbine is positioned in the wind passage and the turbine is rotated by wind passing through the wind passage. A generator is mounted in the generator space and the generator is in mechanical communication with the turbine. Thus, the turbine rotates the generator when the turbine rotates thereby facilitating the generator to produce electrical current. The generator is electrically coupled to batteries in the vehicle to charge the batteries.

The present invention relates to a wind power generator for street light comprising: a post member installed vertically; a central fixed shaft member installed horizontally on an upper portion of the post member; a first blade member rotatably installed around the central fixed shaft member and including a first blade rotated by wind on one side thereof; a second blade member rotatably installed around the first blade member and including a second blade rotated by wind on one side thereof; a cone member having an inclined shape at a specific angle so that wind smoothly moves toward the first blade member and the second blade member, and a power generation module rotated by the first blade member and the second blade member to generate power. According to the present invention, the first blade member and the second blade member can supply sufficient torque required for the rotation of the power generation module and can increase power generation time by driving the power generation module with the double blades. In addition, it is possible to minimize the installation space and reduce the size of the wind power generator by installing the first rotating shaft and the second rotating shaft in a double layer structure.
