Airborne Wind Turbine Could Revolutionize Wind Power

Airborne Wind Turbine Could Revolutionize Wind Power

The secret to the air turbine design lies in using a fraction of the material necessary for a standard wind turbine. A conventional 1-megawatt wind turbine can weigh more than 100 tons, but Makani’s airborne turbine only uses a carbon-fiber wing and lightweight rotors of their own creation. The company says its 1-megawatt airborne turbine system will weigh a tenth as much and have an installed price half a normal turbine, but with the same rated power. “We expect the cost to be around 3 cents a kilowatt-hour,” said Hardham. “That’s getting lower than a lot of coal-fired generation at the moment.”
