something to watch out for

Hope the doom sayers don't take this and run with it! Not the best promotion for large scale wind power.

    Yes, there are a few other threads on here with that story/link.

    This is a perfect example why someone should only purchase a third-world country, sweat-shop made, American-marketed turbine..........

    I couldn't view the link. Does it still exist?

    If I remember correctly, the link was another version of this Danish wind turbine that failed in high winds (apparently an older system/design where the hydraulic brake failed to stop the turbine--so it eventually over sped and the blade system failed--taking out the whole tower).

    Here is a YouTube version of the event. Same event was posted here a bit earlier.

    Thanks Bill.
    I don't understand Noodles reply. Was he/she just being sarcastic?

    Yes Kimberly,

    Noodles was being sarcastic. Even an well engineered wind turbine system, from a European country with a long history of wind power implementations still can have problems as their products age (and possibly maintenance issues) and one can get "energetic disassembly" (blades have been found up to a mile from the site when a turbine has failed--don't know about specifically this event).

    There has been a lot of activity from (poorly built, mass marketed) Chinese built systems and the danger of putting one atop 120' tower on a 50'x100' lot in a suburban environment is not always well understood by the general public. Wind-Sun commented a few days ago on another thread, that probably the number one problem they see is failing blades. Falling objects from a tall tower should scare anyone.

    Even the NYTimes is publishing fluff pieces for wind turbines...

    Haha I love that term. Perfectly describes my first attempt at a "home made" wind turbine. Spent weeks forming a beautiful 14 foot long blade of wood. Was shocked by the power it produced. Then I came home one wk-end and found a six foot portion of the blade sticking out of the barn roof, where it had been driven in like a giant knife.
    Except for a one foot long tip, the rest of the blade was never seen again.
    Now I know it had been subjected to "energetic disassembly". Haha

    that is a good play on words. kind of reminds me of the old tv show/movie "the fugitive" as the episode/segment can be 'parts on the run'.:roll:
    it can also be called "freedom flyer" instead of frequent flyer as the trip is one-way. good thing i'm not in the comedy business.:p
