Southwest Windpower designed the Skystream line to be residential wind turbine. However, they are discovering that these little turbines can find uses in far many more places than just the neighborhood backyard.
The latest use is in downtown Portland Oregon. Four wind turbines, rise 45-feet above a 22-story building. The turbines do not generate much of the building's energy needs (about as much as it takes to run the elevator) but the turbines are just the icings on the cake for this building that is designed so efficiently, it is expected to receive not one, but two Platinum LEED certifications — for new construction and commercial interiors.
