Now, windmills are breaking into a new frontier. Though still in its teething stages, the "urban turbine" is a high-tech windmill designed to generate energy from the rooftops of busy cities. Lighter, quieter, and often more efficient than rural counterparts, they take advantage of the extreme turbulence and rapid shills in direction that characterize urban wind patterns.
