The life of a wind turbine can be pretty precarious. The blades—made of laminated materials, such as composites, balsa wood, carbon fiber, and fiberglass—can reach speeds up to 180 miles per hour at the tip, which means even small particles in the air can cause damage to the surfaces. It’s probably no surprise that lightning […]
