    Classic! This guy's got a real sense of the big picture.

    One collapsed about 10 miles away here in Campbeltown in Nov last year.

    Incidently, Vestas, the manufacturers of the two turbines have a factory here (just down below my farm in part of the RAF Machrihanish air base) that is due to close at the end of the year, with a lose of 92 jobs, just another blow for our small community. Its just typical of big companys with record profits and orders coming in and setting up in towns for the grant money, and then disappearing ater 6 or 7 years to the next place and leaving the folk out of jobs.

    I'm visiting Vestas next week in Denmark, I'll see what i can do ;)

    (I work for Hansen Transmissions, a manufacturer of gearboxes for wind turbines and Vestas is our biggest customer...)

    we've just received some torque wrenches to calibrate from a firm that installs wind turbines.

    All 50 of the tools failed, Drastically!!!!

    I'm glad i don't live by one!

    Makes you wonder then, why people are going wild with these wind farms. Wind, fire!!!

    They just need Earth, and its a band!

    You think they would build them with some more strength really it's a bit ironic that a windfarm can be broken by wind isn't it?

    Well, and when they catch fire!

    normally the maximum speed of the rotor is limited by the control system of the turbine. When the wind speed is higher then the speed range that the turbine is designed for, the turbine should shut down automatically.

    It is impossible to design a turbine to whitstand the extreme rotor speeds shown in the movie, because the centripetal forces in the rotor blades increase extremely quickly once the maximum design speed is exceeded. Also, the blades of the rotor will bend more and more at the higher speeds, and eventuelly one of the blades will hit the tower...
