MICRO WIND TURBINES: Small Size, Big Impact

Conventional wind turbine technology has been a bit out of reach for most residential consumers living in urban areas—until now. Researchers at Hong Kong University and Lucien Gambarota of Motorwave Ltd. have developed Motorwind, a micro-wind turbine technology small enough for private use in both rural and urban environments. Unlike large-scale wind turbines, Motorwave’s micro-wind turbines are light, compact (25 cm rotor diameter), and can generate power with wind speeds as low as 2 meters/second. The gear-like turbines can be linked to fit just about anywhere and a row of eight turbines costs just $150 for now (prices may decrease once the turbines are mass produced). A portion of the revenue raised from the sale of Motorwind turbines (available for purchase here) will be donated to Hong Kong University to continue researching renewable energy technology.
