Manufacturers of wind turbine gears face some unique challenges, not least of which is producing components that are durable enough to withstand the inconstancy of wind and exposure to the elements. As Rick Sisson, director of the materials science and engineering program at Worcester Polytechnic Institute (WPI) explains, the university is applying its lengthy experience in working with car and aircraft engines to improve the viability and reduce the cost of turbine gears and bearings.
