Turning High-Rise Rooftops Into Wind Farms
Eastern Wind Power (EWP) is a Cambridge, Mass.-based startup that has developed a 50-kilowatt (kW) vertical-axis wind turbine (VAWT) called the Sky Farm. The VAWT is designed specifically to be mounted on the roofs of high-rise buildings. The company has partnered with Siemens to develop its small wind generator and inverter system. The company erected its first prototype Sky Farm at the Martha’s Vineyard Airport in 2010. The turbine is now grid-connected, and producing power for the airport.
