The U.S. Department of Energy has awarded a $24-million grant to Beacon Power Corporation. The funds are earmarked for the construction of its second flywheel energy storage plant. The 20 MW storage plant will be located in Chicago, Illinois.
The 610V Aeroturbine is custom made to suit the building’s architecture. The wind turbine works effectively in a minimum wind speed of 10 miles per hour. Including the alternator, the aeroturbine weighs about 450 pounds. As the urban setting wind turbine is modular, it can be stacked if additional power generation is required.
The Whisper 100 windmill includes three blades that are fiber reinforced and injection molded. The upgraded yaw shaft of the wind turbine carries the current to batteries with more efficiency.
The site was located near the scheduled ancient monuments. For the wind farm, consent for three 1.5 megawatt wind turbines was granted.
The MADE AE-20 wind generator incorporates rotor, which has a diameter of 20m. It uses three fixed pitch rotor blades and the rotor has a velocity of 46rpm. This wind turbine is mounted on a conical trunk tower, which has a height of 21m.
Siemens Energy and Meridian Energy have signed an order for the supply of 28 SWT-2.3-101 wind turbines for the Te Uku wind power project near Hamilton, New Zealand. The wind farm is scheduled to come on line in 2011 and will have a capacity of 64 megawatts (MW), which is enough power to meet the needs of 30,000 households. It is estimated that the project will save approximately 145,000 tonnes of CO2 emissions annually.
The Airlift 1 H.O. water pumping windmill’s blades are made of 6061 T-6 tempered aluminum. To begin its operation, this water pumping windmill requires a wind speed of 5 to 8mph.
