Marquiss Wind Power, which makes small, square wind turbines for commercial rooftops, announced its acquisition Tuesday of wind-energy company Cirrus Technologies under undisclosed terms.
"Together, we have a strong family of patents specific to small wind that will allow us to deploy better, more effective products than previously marketed in the wind energy sector," said Paul Misso, CEO of Marquiss Wind Power.
The Folsom, Calif., company makes 19-foot-tall Aeropoint wind turbines featuring a star-shape framework within a square frame. The Desert Research Institute of Nevada and an unnamed utility have reportedly tested turbines using some of the seven patents held by Cirrus.
Relatively modest-size turbines with a more traditional shape include the Skystream from Southwest Windpower, which provides up to half the power used by a zero-net-energy home in San Francisco. Other small wind turbines come from AeroVironment and Mariah Power.
Marquiss Wind Power raised $1.3 million in series A funding in January through Velocity Venture Capital and Strategis Early Ventures.
