Awww. Wind Turbine Fell Over

One down, three to go…

sunshine hours

Mangled Wind Turbine mercilessly attacked by cold or wind or shoddy construction or all three.

“Whenever we came out, we noticed this big mound up there. Then we noticed one of the windmills was missing,” Steyer said.”

    As I said on Sunshine Hours, the only good one is a dead one.

    Such a fine sight to see: Eagles revenge 🙂

  3. BoyfromTottenham says:

    Or did the warranty expire? But seriously, is anyone asking the owners of these things whether the manufacturer / installer of it is in breach of contract? And if not, why?

  4. Cheyne Gordon says:

    It’s not dead. It’s RESTING!

  5. J Martin says:

    Although I hate these modern wind turbines, one could argue that they are a good thing in that they substantially increase the amount of co2 going into the atmosphere since they produce less than half the power over their lifetimes that was needed to manufacture, install, and service them. Of course then there is also the destruction of the UK economy that these things bring.

  6. PeterMG says:

    An engineer for one of the big German manufactures told me that this is going to happen a lot. They get the Chinese to manufacture the gear train, and the tolerances and materials have to be exact other wise they fail. Being exact is not in the Chinese’s nature, and close enough is often good enough. These things are more of a compromise than most realise and it only takes a small fault and the gear train can seize. if this happens when under load (most common) the turbine slows very quickly and transfers all that momentum into the foundations or the tower. Crash goes the turbine.

    Yes they can make all the bits stronger, but the costs rise and efficiency drops. Most of us realise these monstrosities are a disaster, but I believe they are even worse than we realise and very few will still be producing in ten years time. The question is will we be able to put all the people in jail who decided to build these things against good advice not to.

    Peter: Spot on. Gearbox failure is the nemesis of these ungainly devices.

  8. Joe Lalonde says:

    TB,

    They’ve decided to harvest power on the ground and chop the legs of animals…less costs on crane rental for maintenance. 🙂

  9. I’ve pointed out many times gearboxes are not always present. see http://www.enercon.de/p/downloads/EN_Productoverview_0710.pdf

    How many towns had to be evacuated? How are they handling the toxic waste? How long are people excluded from the exclusion zone?

  10. hunter says:

    Look at the twisting of the pylon. That was a *lot* of torque getting transferred in a sort period of time. Did the gearbox fail, or did the feathering fail?
    Cheyne: +1

  11. Truthseeker says:

    What are ten wind turbines that have fallen to the ground?

    A good start …

  12. thefordprefect: yes we know all about the gearless, direct-drive generators with all that toxic waste left behind in China from extraction of the neodymium used in the magnets. See http://www.dailymail.co.uk/home/moslive/article-1350811/In-China-true-cost-Britains-clean-green-wind-power-experiment-Pollution-disastrous-scale.html

    Big magnets velly dangerous.

    Great question! Let’s check…
    http://www.dailymail.co.uk/home/moslive/article-1350811/In-China-true-cost-Britains-clean-green-wind-power-experiment-Pollution-disastrous-scale.html

    Oh…

    Perhaps we should check solar panel production in China as well? Or the consequences of bio-fuel land clearing in Indonesia? Or maybe check with those machine-gunned to death in Africa in “contractor” disputes with villagers over bio-fuel land use? Or the ever growing slaughter of rare species by your protected bird blenders? Maybe the thousands dying from energy poverty in northern Europe?

    Or perhaps,Mr. “Ford Prefect” you can just wrap your towel around your head and pretend that you and yours in the “environmental movement” have not just been involved in one of the the most insane and unnecessary losses of life, human and otherwise, in all of recorded history.

    Adding radiative gases to the atmosphere cannot reduce the atmospheres radiative cooling ability. To describe your insanity accurately I would not just need to breach Godwin’s rule, I would have to pass light speed doing it and go to plaid!

    [Reply] No need to get personal. Say what you like about the cult as a whole though.

    =====================

    OK the same company produces theirs without gearboxes and without neodimium (no rare earths)
    They simply rectify the output and use other electronics to generate synchronous 50Hz power to the grid.

    This has the advantage of fast synchronising and the ability to produce power into a “shorted” grid – a useful feature when trying to reconnect a damaged grid.

    I covered this here:

  16. I think it ate my post
    so in brief
    No neodimium
    No gearbox
    Fast synch

    Ford; no idea why they went to spam.

    “This turbine wouldn’t Voom if you put 4 million volts through it”

    Well somebody had to…

  19. PeterMG says:

    Ford prefect you are flogging a dead horse get over it. Wind Turbines are hopelessly uneconomic. Of course all the issue with mechanics and electronics and electrics can be overcome. But at what cost. So far it has been to the detriment of the poor around the world and especial in our own country, something that the new bread of environmentalist shows scant regards for. And lets not pretend that just because the turbines you champion don’t have gearboxes that they don’t have another achilles heel where a compromise has been taken to keep the product within a price that the subsidy farmers will pay. We maybe just haven’t seen it yet.

    From a philosophical point humans only truly innovate when market forces, free of competition destroying regulation, are bought to bear on products where there is real demand. There is no demand for wind turbines other than that driven by government forcing them on an unwilling population. This is why they will never work. There are just so many better and cheaper way of producing electricity.
