You think with all the technology, someone would have tought about this happening. It's called a brake!
There are so many ways that windmill could have been fitted to spin only so fast.

ps...centrifical clutch come to mind.

In this case the mechanism that limits the speed of the windmill is called a "break"!

I don't think that they use breaks. I believe that they change the pitch of the blades to limit the speed.

The ones I looked on out Dakota trip last summer (Minot ND) only pitch the last few feet of the blade tip but I saw it bring one down to a dead stop in a minute in a a fairly good wind. Still not sure why they feathered it since the twin next to it was still going. My thought was it was easier to do load leveling with this than coal/synfuel fired plant down the road in Beulah.

When I saw this topic, I thought you meant the wind generator failure in texas over the weekend, where the wind in the panhandle suddenly dropped and texas nearly went into rolling blackouts. They were saved by... (drumroll, please) thousands of small diesel generators! Which fired up at industrial sites across the state and took up the delta from the 4% of the state electric load the wind turbines normally provide.

I look forward to seeing 20% of our energy provided by wind and solar...
