  • Wind > High Altitude >
    The Kite Wind Generator - An Italian company is installing Kite Wind Generators, or KiteGens that are mounted on giant movable poles. When wind blows these kites come out of funnels on a pair of high-resistance cables to control direction and angle. As the kites blow left then right, they pole movement generates electricity.

    Barros & Pereira's cross-wind_bridge - As vehicles cruise down the road, they kick up a wind that designers Barros & Pereira propose to harness via a from a network of 2,188 light-weight rotating panels on a pedestrian bridge to power the bridge lights at night -- a sort of wind tax on the passing vehicles.

    Airplane almost hits ship kite - Now that more and more ships are using skysail kites which sometimes fly as high as 300 meters (~1000 feet) to help tow them along to conserve on fuel, a dangerous situation is posed to airplanes by both the kites and the tether. (Examiner/PESN; Sept. 18, 2009)
  • Wind > Offshore \ Largest >
    Denmark Brings World’s Largest Offshore Wind Farm Online - Denmark is launching the world's biggest offshore wind farm this week. Using 91 turbines scattered across 35 square kilometers, the Horns Rev 2 farm, built by Danish utility company Dong Energy, will be able to produce 209 megawatts of power – enough for a staggering 200,000 homes.

    Slip Rings for Wind Power (video) - Slip Rings by Moog Components Group, utilize fiber brush sliding contact technology, making them a “no maintenance” rotary devices for transferring electrical power and signals; and eliminates the need for common slip ring maintenance procedures such as vacuuming of brush debris, lubrication, regular inspection for wear, and brush replacement. (Engineering TV; June 22, 2009)

    Wind Could Provide 5X World Energy Needs - A new study in the Proceedings of the National Academy of Science estimates the earth's capacity for wind power if plausible areas were put to use with 2.5-MW wind turbines, and 3.6-MW off-shore turbines (within 50 nautical miles in ocean depths less than 200 meters) showed that wind energy could provide over forty times the world's current electrical consumption and over five times the global use of total energy needs. (Mongabay; June 22, 2009)
  • Featured: Wind > Horizontal Axis >
    Honeywell Wind Turbine by EarthTronics - EarthTronics, of Michigan, USA, says they have developed a wind turbine for residential and business customers that produces the highest output while having the lowest cost per kWh installed, at 1/3 the cost of any other wind generator on the market, and will be available through Ace Hardware stores in the Fall. Skeptics say this is hype not supported by actual deployment. (PESWiki; June 18, 2009)
  • Wind > High-Altitude >
    Results from High-Altitude Wind Study Promising - In the future, will wind power tapped by high-flying kites light up New York? A new study by scientists at the Carnegie Institution and California State University identifies New York as a prime location for exploiting high-altitude winds, which globally contain enough energy to meet world demand 100 times over. (Wired; June 15, 2009)
  • Wind > High Altitude Wind Power >
    Harnessing High Winds With Giant Kites - On overview of various companies and groups seeking to develop viable, reliable methods of harnessing energy from high altitude winds, which carry hundreds of times more energy and are more constant than those near the ground. A look at Delft University of Technology's Laddermill; Google-supported Makani; University of Sussex; and Kitegen of Italy. (Alternative Energy News; May 20, 2009)
  • Wind > Augmentation
    Donut-Shaped Plastic Improves Turbine Output By 30% - Leviathan Energy has come up with a way to improve wind turbine efficiency that has nothing to do with the size or angle of the blades. The company's Wind Energizer is instead a donut-shaped structure made of plastic and steel that wraps around the base of the turbine to maximize wind velocity aimed at the blades. (EcoGeek; May 1, 2009)
  • Wind >
    SWIFT Wind Turbines - Renewable Devices Swift Turbines Ltd. has developed the SWIFT Wind Turbine, a quiet, building-mountable wind turbine, capable of providing a cost-effective renewable energy source for domestic, community and industrial use. Developed in Scotland and manufactured and distributed in the US by Cascade Engineering.
