Wind power breakthrough: Carbon nanotubes make strongest, lightest blades ever

Wind power breakthrough: Carbon nanotubes make strongest, lightest blades ever

Bigger wind turbines can harvest more wind energy, but they're also heavier, which makes them less efficient. But a scientist at Case Western Reserve University figures he can solve this fundamental dilemma by throwing carbon nanotubes at it. If you've heard of carbon nanotubes , it's probably in the context of super-awesome bicycle frames or high-performance tennis rackets and golf balls . Adding carbon nanotubes to the usual mix of plastics could give turbine blades the same boost. The results suggest that future turbine blades could be lighter, bigger, and harvest more energy. In a comparison of reinforcing materials, the researchers found carbon nanotubes are lighter per unit of volume than carbon fiber and aluminum and had more than 5 times the tensile strength of carbon fiber and more than 60 times that of aluminum. They could also last longer. Fatigue testing showed...
