Windmill go boom

I don't know if it was posted already. If it was the same one that was on The Hisstory or TlC channels, the problem was failure of the governor resulting in overspeed condition. Shed one blade which caused rest of problem.

The answer is simple. It was a failuire of the governor. Resulted in overspeed. One blade failed due to exceeding stress limit. Unbalance caused remainder of problem. The governor failure was mentioned somewhere in one of the shows.

No need to go into any "conspiracy theories" simple engineering explanations cover it.

We did a convention in Las Vegas, and they brought in one of the blades. It was the longest load I have ever seen come into the LVCC. I have seen two or three of these going down the Interstate, but looking at them in National Geographic, they must be some of the smaller ones compared to what's in Europe. The ones on the Interstate were a caravan of guide cars, and I would estimate that they were about 125' long. In England and Europe, they can be built dockside, and then barged to the towers, never getting on asphalt.

I would say that something failed, as those blades are meant to rotate so that when they start spinning fast, they turn so that the edge hits the wind straight on, therefore creating no spin.

No doubt about it in my mind as to what happened. Something or someone screwed up. Yep. Definitely.

re: "Then there are those exotic spirally ones that spin on a vertical axis. Anyone ever seen those?"

Weren't those used on ships?

I haven't seen any bird kill problems, but there have been reports of a few bat kills.

Would that be because the birds learned to avoid them, or all the birds were dead?

I do seem to remember the late Senator Kennedy objecting to some whirly- gigs because it would destroy the view.

It disrupts the feeding habits of the Three Legged Jumping Snail and causes pet Pot Belly Pigs to stop that cute little snorting sound they make which the pet owners find so adorable.

It's called feathering. With the blades fully feathered, no brakes would be necessary.

One of the blades hit the mast as it broke.

ISTR a Cousteau windjammer that used them. I think they were "sails",though,not power generation.

I'm glad you cleared that up for me.

Here's a whole page of vertical-axis wind turbines:

There have been some very interesting programs on about the development of acoustic weapons. It was on The Military channel if I remember correctly. Back when I was a damn hippie freak, attending loud concerts, I had some bone rattling experiences from the large acoustic transducers in front of the stage. It's funny how our military uses that same music to torture man caused disaster suspects. *snicker*

Three windmills for $9.99 with valuable coupon!

They were doing it to hippies back then, too.

Did you marry the girl who just can't say 'Nuu.. Nuuu, Nuuu!!!, Nuuu..."?

Yup! Parabolic speakers.

"Application: Commercial application for parabolic speaker system are listed as spaces like Airports, Shopping Malls and stadiums. They are also used in by the police in situation like crowd control, hostage crisis, anywhere where long throw intelligable audio is required."

So you saw "A Clockwork Orange" too.
