has anybody else seen the video of a big windmill going out of control?? i saw a video of a windmill in denmark losing it breaking system in a strong storm.one of the blades shattered into a million pieces and the other two blades hit the tower.it shattered those blades and crushed the steel tower.the tower snapped at the joint in the tower and the top half of the windmill fell to the ground.when,the two blades hit the tower it also ripper apart the housing with the gearbox and ect in it.
the scary part is pieces went for a half a mile from where the windmill was.when,the windmill went out of control they evicted a 1/4 mile area around the tower and thought they would be safe.nobody got hurt but they very well could have.

AND

If anyone wants to worry about what COULD happen, then, all foggy highway areas NEED to be closed. FOG, DOES create injuries and deaths.

Not being a smarta$$ but, this society worrying about EVERYTHING that MIGHT happen, needs to just look around. There's NOT enough worrying to go around.

Like the smog/fog on the turnpike they blamed on the pulp mill down in Knoxville. Some serious accidents happened there. Raised the stacks higher and problem was solved. Or at least I never heard any more trouble.

I'm with Harold's thoughts on this too...as for me, the greater (est) danger is getting into the auto, and onto the highway. Be safer to be in the military in Iraq.

Yep the Bowater paper mill is what caused the fog up there. It actually is a little place called Charelston TN. The stacks and them dumping hot water into the river is what caused the fog, they denied the hot water but you ask any old timer up there and they would tell you there was no fog before the mill came in.

I've been there.

But, it's like this area when we call it Centreville. I'm not actually in the village. I'm up in Royalton, 5 miles northwest. The old rural route address scheme was always addressed as Centreville R.R. # ??. We never knew where we lived until 911 came along.

all i asked is if anybody saw that video. i,am very much pro windmill but,watching that mill come apart was impressive.
they built 198 windmills of that size and type a hour south of me.some of the parts came right by my house.it,s hard to believe the blades could hit that tower so hard it flattened it and took the whole top half down.

Yes Delbert, I saw what I believe to be the same video on a T.V. show named "Destroyed in Seconds". Impressive as far as the damage caused by the blades. Appparently, the blades were spinning at four times their rated capacity immediately prior to the first blade snapping off and the other two blades shearing the metal tower. Thankfully no one was injured. Here in Oklahoma about sixty miles from me there is a wind farm. Andy

yep,jeff thats it the braking system failed in a strong storm and that was the result.

Did the brakes fail because of the storm or was that a mechanical SNAFU that happened at the worst possible time?

twobears · « **Reply #11 on:** September 01, 2008, 11:20:12 am »

it was a mechanical SNAFU at the wrong time.i would think they would have another way to shut the windmill down if the braking system failed.that was a big lose of money.

Windmills generally have redundant braking systems. Both failed . It might be time to look at triple redundant braking systems.

to me that shows just how much power is in wind.

That reminds me of a scene from the Jody Foster movie "Contact" The transporter that is built is sabotaged by a bomb and comes unglued. Pretty good old movie. You can see the scene I am talking about near the end of this youtube clip.

Thanks Jeff.

There aren't enough hours in the day already. Now I have to go out and rent the movie so I can see what happened.

That kind of turbine meltdown would kill the industry if it happened here.

you would think they would have the technology to just turn the wind mill out of the wind ( so it didn't face directly into it) these windmills don't have a tail, there is a motor to change the dirction.

We need " windmill control" quess thats why their out on wind farms not in town.Everything man builds is prone to failure.Wonder if the dutch had that problem years ago??

Radar67 · « **Reply #19 on:** April 03, 2009, 09:37:53 am »

Speaking of controls, does anyone know of a speed control that would keep say an alternator from going over a certian rpm?
