I'm not terribly familiar with wind power generation, but if car manufactures can make a CV clutch transmission capable of handling 250ft lbs, would it not be possible to do the same for a wind tower? Let the blades vary speed with wind, but keep the alternator/generator at a relatively efficient range. Seems simple enough. It might work well with smaller scale wind turbine, relatively small forces acting on them. Not sure if the mechanics and failure rates could keep up with the super-scale turbines.
If it works for snowmachines (mobiles..sigh) and cars, why can't regular maintenance work for wind turbines?
