A little bit of irony regarding "clean energy"

I think the largest Vestas blade is half the length you state here, or 126meters in diameter. So the blade tip speed will also be closer to half or 340mph. I may be wrong though.

I used to work a lot with the guys that serviced the wind turbines for Xcel Energy at the Colorado/Wyoming border out of one of their power plants. They said they got protested for wanting to install a new gas turbine one day, then the next day got protested by another group for wanting to install wind turbines. Lose/Lose. Can't make everybody happy. Sucks for the bird.

Yup, you are correct...[facepalm]

fixed it.

Still faster than I would have thought.



But so what, birds are getting whacked by the blades. We have had at least 5-10 birds die since May just flying into our window at home.

Double pane windows should be outlawed immediately and replaced with single pane windows. That is of course as long as those double pane windows weren't purchased after July 1, 2013

hahahaaaaaaaaaa[LOL]

We all ran over there and were heartbroken to find the poor bird lying beneath the machine, in perfect condition apart from blood and slight trauma on the head - but it was stone dead. Cries of sorrow and anger from the assembled birders began to turn into discussion as to what would happen to the bird's corpse, as we took pictures of it lying there.

Would have been hilarious if that had ended with " a fox snatched the corpse and ran off"
