The method comprises the steps of operating two or more blades of the wind turbine in a stall condition, detecting if the tower oscillates beyond a predefined level, and establishing... http://www.freshpatents.com/Wind-power-generation-system-dt20090813ptan20090200803.php Tue, 18 Aug 2009 22:16:28 -0700 In a wind power generation system, an AC input of a unit for coping with system faults is connected to an excitation converter and a DC port of the unit for coping with system faults is connected to a DC port of a converter through resistors. A plurality of energy... http://www.freshpatents.com/Compressed-air-storing-electricity-generating-system-and-electricity-generating-method-using-the-same-dt20090813ptan20090200805.php Tue, 18 Aug 2009 22:16:28 -0700 Disclosed are a compressed air energy-storing electricity generating system and an electricity generating method using the same, in which air of a high pressure is injected into a tank laid under the ground using midnight electricity and surplus produced electricity, and the air of the high pressure in the tank... http://www.freshpatents.com/Wave-based-power-generation-system-dt20090813ptan20090200806.php Tue, 18 Aug 2009 22:16:28 -0700 The wave-based power generation system has a buoy or float retained by a cable that enters an underwater power generating station. The cable enters the station housing through an inverted U-tube having upturned inlet and outlet ports, which prevent water from entering the housing. The buoy cable passes over an... http://www.freshpatents.com/Adams-alternative-energy-system-dt20090813ptan20090200807.php Tue, 18 Aug 2009 22:16:28 -0700 A system that may turn electricity generating devices with no emissions. The device is comprised of three major portions. The main intake portion, the collection tank portion with water pump, and the air exhaust portion. All of which require each portion to operate. The main intake portion may be several... http://www.freshpatents.com/Pole-mountable-wind-turbine-support-system-dt20090813ptan20090200808.php Tue, 18 Aug 2009 22:16:28 -0700 A support for supporting a plurality of wind turbine generators on a pole may be raised or lowered. The support accommodates a solar voltaic array attached to the pole and allows the wind turbines to be raised and lowered past the attached solar voltaic array. Waste heat from the solar...
