Howdy Horace,
All the math in the world cannot reconcile adapting blade type windmills to electric generators. for fun or profit. Siemens et al controls much of the manufacturing of these monsters. The US gov't subsidizes them with tax offset credits and the electric power wholesalers sell the green power at plus rates with the come on that green is in and everybody should help. At any one time as many as 1/3 of the mills are down for maintenance. The cost of repairs including crane rental fees to remove a generator or blade 100 plus feet above ground gets sorta costly. Has anyone done an analysis on cost- subsidy vs power sales? Blade fatigue do to pylon harmonics take the fun out of investing in these "mills" regardless of the hype about green. Richard
