Rooftop Wind Turbines in Portland

Southwest Windpower has just installed 4 wind turbines to the new residential tower on 12st street in downtown Portland, Oregon.  The 4 wind turbines will power a portion of the buildings electrical needs and will serve as an experiment for the viability of rooftop wind power.  The Energy Trust of Oregon paid for the turbines atop the LEED Platinum certified tower where they will only provide about 1% of the total power for the building.  See more (including a video) at Jetson Green.
