20110084495 | VERTICAL AXIS WIND TURBINE - A vertical axis wind turbine has a stationary circular core and a rotor rotatably supported about the stationary core. The rotor has a radially extending rotor arm with a wind engaging blade locate at its distal end. The blade has at least two straight blade sections of which at least one blade section is inclined obliquely at a first angle. | 04-14-2011 |
20090220342 | SHAFTLESS VERTICAL AXIS WIND TURBINE - A shaftless vertical axis wind turbine has a stationary hollow core having inner and outer circular walls with a void between the inner and outer walls. A rotor is rotatably supported about the core and has a plurality of radially extending rotor arms each having a wind engaging rotor blade located at a distal end. | 09-03-2009 |
20090220339 | WIND DEFLECTOR FOR WIND TURBINE AND WIND TURBINE INCORPORATING SAME - A wind deflector for a wind turbine has a vertical wind deflecting surface movable in a circular path about the wind turbine for facing a prevailing wind direction. | 09-03-2009 |
20090218823 | WIND TURBINE STRUCTURE HAVING A PLURALITY OF PROPELLER-TYPE ROTORS - A wind turbine structure has a vertical core that supports multiple stages of rotor support frames and power generating units, each rotor support frame comprising an annular carousel rotatably located about the core and having at least two radially extending arms, and at least one pair of propeller-type rotors located respectively at distal ends of the radially extending arms. Each rotor support frame can rotate around the vertical core independently. Each rotor support frame further comprises a wind deflector. | 09-03-2009 |
