    Windkraft: TÜV sieht in den Anlagen „tickende Zeitbomben“ - WELT
    I`ll post the quotes in German and translate each one
    Windkraftanlagen werden zu „tickenden Zeitbomben“
    Wind energy parks are turning into ticking time bombs

    Anfang Januar im Landkreis Schaumburg: In einer Windkraftanlage fällt die Steuerungselektronik aus, der Rotor kann sich nicht mehr nach dem Wind ausrichten. „Nachdem zuerst einige Teile eines Rotorblattes zerbrachen, knickte der Turm des circa 70 Meter hohen Windrades gegen 13.30 Uhr ein und die gesamte Anlage stürzte zu Boden“, heißt es im Bericht der Polizeiinspektion Nienburg.

    Schaumburg, January Police report:
    A failure of the electronic system which orients the rotor direction caused rotor blades to disintegrate and shortly after at 13:30 the entire structure collapsed crashing to the ground


    Zwei Wochen später bei Bad Driburg: An einem Windrad brechen zwei Rotorblätter ab, eines liegt hundert Meter entfernt im Wald. „Ein dickes Rohr hat sich wie ein Pfeil in die Erde gebohrt“, berichtet die „Neue Westfälische“: „Im dichten Nebel sieht die Landschaft um das zerstörte Windrad aus wie ein Kriegsschauplatz.“

    Bad Driburg 2 weeks later : 2 rotor blades break off a wind turbine. One landed 100 meters from the site and a heavy pipe was bored into the ground like a projectile. The site looked like a war zone.

    Acht Wochen darauf im westfälischen Borchen: Bei einer 115 Meter hohen Anlage ist die Bremstechnik nicht installiert. Der Rotor dreht sich immer schneller, bis zwei der 56 Meter langen Flügel „in einer Wolke aus Glas, Kunststoff und Füllmaterial zerfetzen“, wie das „Westfalen-Blatt“ schreibt. „Messerscharfe Glasfasersplitter“ fliegen 800 Meter weit.

    Borchen, Westfalen, 8 weks later. A faulty break mechanism on the 115 meter high wind turbine failed to limit rotor speed.. 2 of the 56 meter rotor blades exploded into a cloud of glass, plastic and filler material and razor sharp fiberglass splinters shot as far as 800 meters


    These are just some examples and the number of such incidents is growing. The TÜV is planning to treat wind turbines like other industrial sites in the future which means much more stringent requirements have to be met to get the materials and construction certified.

    Meanwhile another analysis showed that even in windy areas turbines interfere with each other when 10 MW per square kilometer are present that they can only deliver 11% of that.
    The Max Planck institute which was part of the study determined that even in good areas for wind turbines you can hardly expect more than 1 watt per square meter.

    Sounds about right... One disintegration per 50 turbines every year...

    Again, stinky 'facts' from the broad ass of Silly Billy. Here are the real figures;


    Annual blade failures estimated at around 3,800


    14 May 2015 by Shaun Campbell

    WORLDWIDE: Wind turbine rotor blades are failing at a rate of around 3,800 a year, 0.54% of the 700,000 or so blades that are in operation worldwide.

    Siemens was forced to curtail 700 turbines worldwide after a B53 failure
    The figures, from research carried out by renewable energy undewriter GCube, were delivered by Andrew Bellamy, former head of Areva's 8MW blade programme, in his opening address to Windpower Monthly's blade manufacturing and composites conference in London on 12 May.

    Bellamy, co-founder of renewables advisory firm Aarufield, pointed out that blade failures are the primary cause of insurance claims in the US onshore market. They account for over 40% of claims, ahead of gearboxes (35%) and generators (10%).

    The wind industry also faces a struggle to secure the carbon fibre materials it needs for lighter and stronger blade designs, warned Bellamy.

    "There's growing competition for these materials from the automotive and aerospace industries," he said. "And they are willing, and able, to pay more than we are."

    Recent examples of blade failures include a blade from a Vestas V90 3MW turbine that snapped on a wind farm in the north of Denmark last year. At the time, Vestas said the winds were not particularly high.

    In another case last year, GE was forced to replace 33 blade on its turbines at a Michigan wind farm after a blade broke on the project.

    GE put the failure down to a "spar cap anomaly". It was the second such incident involving the 1.6-100 model, and was followed by a third at the 94MW Orangeville wind farm in New York State, also in November.

    Possibly the biggest blade issue was faced by Siemens in 2013 when it was forced to curtail around 700 turbines worldwide. This was caused by a bonding failure in its B53 blade.

    Imagine what travel would be like had they decided airplanes were too dangerous to keep developing them and using them.

    Typical lip-flap-yap-yap "come back" cue card that is being used over and over again by Hillary`s sockpupppets .
    Imagine what would happen to windmills if the NTSB who can ground an entire fleet on the basis of 1 single nut or bolt posing a danger would have to certify windmills.

    However, hundreds of peoples live are not in danger from the failure of a single windmill. And what the fuck does politics have to do with the failure rate of windmills? You are getting senile, old man.

    Hahaha this is like a game of mole-bashing, bash one frigidweirdo and another one pops up:
    "And what the fuck does politics have to do with the failure rate of windmills?"
    The only thing that keeps windmills going is politics which wants no part of having anything to do with the failure rate of windmills. And as far as me being a "senile old man" in your opinion is an ineffective insult because it came from the kind of person, of which I could beat 10 of that kind in a simultaneous chess game while I am reading my news paper. I would be alarmed if I were on the "like-list" of somebody like you, because that would put me in the same "class" like Maxine Waters and "Pocahontas"

    Oh, you want typical answer, your "answer" is just that.... Nothing to actually reply to... just attacks because you have nothing.

    That part looks like you have some sort of speech impediment in addition to a communication disorder
    Nothing to actually reply to...
    If that is so then why did you type that gibberish and click on the reply button?
    just attacks
    What should we call somebody who cries like a child that he was "attacked" instead of admitting to himself that he failed ?
    ....because you have nothing
    And with that your stupid windmill equals airplanes QC wins the day inside your pea brain.
    Let`s see again what you said:
    Imagine what travel would be like had they decided airplanes were too dangerous to keep developing them and using them
    Now you say I "attacked you" because I said that entire fleets are grounded if airplanes use unsafe mechanical parts....and so far I did not even point out that only a narcissist would delude himself to claim credit for advancing technology solely based on the fact that he is posting "green energy" crap on the internet.
    Wow I never realized that we would not have any airplanes were it not for the kind of people who say we should not use them because they cause global warming.
