Most wind turbine manufacturers stick with giant, commercial-scale turbines, but Marquiss Wind Power is trying to popularize a roof-top turbine suitable for use by ordinary businesses.
The company’s “ducted” wind turbine looks a bit like a 19 foot tall box fan. Despite its clunky appearance, it’s capable of re-orienting itself according to the direction of air flow, while the ducting is intended to increase wind speed as it approaches the blades.
At the moment, two models are sold — one intended for areas with wind speeds of 6-10 mph, and another for higher average speeds. The turbines are intended for buildings between one and three stories tall.
Marquiss received the $1.3 million funding from Velocity Venture Capital, which led, and Strategis Early Ventures. The funding was the Folsom, Calif. company’s first.
