Peak Energy: Better Wind Turbines - 0 views

  •  
    Technology Review has an article on advances in wind turbine technology - Better Wind Turbines. ExRo Technologies, a startup based in Vancouver, BC, has developed a new kind of generator that's well suited to harvesting energy from wind. It could lower the cost of wind turbines while increasing their power output by 50 percent. The new generator runs efficiently over a wider range of conditions than conventional generators do. When the shaft running through an ordinary generator is turning at the optimal rate, more than 90 percent of its energy can be converted into electricity. But if it speeds up or slows down, the generator's efficiency drops dramatically. This isn't a problem in conventional power plants, where the turbines turn at a steady rate, fed by a constant supply of energy from coal or some other fuel. But wind speed can vary wildly. Turbine blades that change pitch to catch more or less wind can help, as can transmissions that mediate between the spinning blades and the generator shaft. But transmissions add both manufacturing and maintenance costs, and there's a limit to how much changing the blade angle can compensate for changing winds.

Inhabitat » Solar Updraft Towers to Generate Food and Energy - 0 views

  •  
    A new breed of solar tower may soon be sprouting up in Namibia, providing the nation with a carbon-free source of electricity and food during the day and night. At one and a half kilometers tall and 280 meters wide, these massive solar updraft towers could potentially produce 400MW of energy each - enough to power Windhoek, the nation's capital. Proposed by intellectual property company Hahn & Hahn, the towers generate energy by forcing heated air through a shaft lined with wind turbines. Additionally, the base of each tower will function as a 37 square km greenhouse where crops can be grown.

Old Coal Mines Adapted to Generate Geothermal Energy - 0 views

  •  
    Recently the town of Heerlen in the Netherlands repurposed an old abandoned coal mine into a brilliant source of geothermal energy. The project takes advantage of flooded underground mine shafts, using their thermal energy to power a large-scale district heating system. Dubbed the Minewater Project, the new system recently went online and provides 350 homes and businesses in the town with hot water and heating in the winter and cool water in the summer.
