OT - Spinning to destruction

Clearly labelled OT - so don't read on further then bitch and then
complain that it chewed up your DL limits.

But - since there has been some past interest here on wind turbines and
power generation - FWIW -

"Wind power may be one of the cleaner, greener energy sources available,
but turbine and blade failures point to dangers that were not
anticipated, says Michael Connellan

David Campbell and his family were asleep in their farmhouse in Northern
Ireland when the 16-foot blade from the wind turbine crashed through the
roof of his home one windy night in January last year. "It was like a
bomb hitting the roof," he told the Belfast Telegraph. "It shattered the
tiles and the blade disintegrated itself."

Campbell was not the only person to see the direct effects of a turbine
failure. Just over a year later, in February, a 200ft Vestas wind
turbine near the Danish city of Ã…rhus disintegrated spectacularly in
high winds when a blade came loose and smashed into the central tower,
causing the whole structure to collapse. The incident was captured on
video camera and footage has been viewed thousands of times on YouTube.

Clearly failed its blade containment tests.

That would explain the camera being in place to capture the event.

Shame they didn't use video equipment of a higher quality, or less
compression when posting.
