Wired UK - Altaeros Energies is to carry out the first commercial demonstration of a high altitude wind turbine, thanks to a partnership with the Alaska Energy Authority. The wind energy company was formed out of MIT, and has developed a 10-metre-wide, helium filled inflatable wind turbine called the Buoyant Airborne Turbine (BAT) that has been tested at altitudes of more than 100 metres above ground.
