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.

    Interesting design. I’d like to try it for my home, but that big thing on my roof would draw the ire of my neighbors. Maybe an array of smaller ones would look better, although it may decrease power conversion.
