After receiving a special permit, we were granted permission to enter the testing zone for the world's largest wind turbines today and view them up close! Their blades measure 75 meters, which is roughly 250 feet.They produce a whopping 6.5 megawatts and the blades span an area the size of about 2 football fields and weight 25 tons each. The company, Siemens, engineered these turbines with a new blade design they call IntegralBlade, in which glass-fibre-reinforced epoxy and balsa wood are poured into a single mold, eliminating use of adhesives or overlapping materials that can cause extra strain when the wind turbine is actually rotating.We viewed them from the ground below and saw how truly gigantic these 75 meter long blades are, especially when they are rotating with the power of the wind.
