U powers up experimental wind turbine

A 2.5 megawatt turbine in Rosemount will provide power for the grid and a full-scale testing ground for new technology. 3M is already planning to test a new innovation: a thin film that puts tiny ribs on the turbine blades. Researchers believe the ribs will reduce resistance and increase performance.
