Wind turbine fire

I have seen these all over the mid west and I never thought of something happening to them before but I could only imagine how bad it could have been if around harvest with wheat or any other dry crops?

Never even crossed my mind for some reason, I bet that could really get a roaring fire on the ground quick cause chances are they will go up in smoke at a very inopertune time....

and windmills are generally built in a windy area...grass fire + wind = bad

You get to chose.

There's been a few of those over the years, I'm sure the power companies will cover any damage.

Why is there never time and money to do it correctly but there's always plenty to do it again

The Turbines here have a 1000 liters of oil in the gearboxes. That would start a good fire.

Wow, that much oil!
There are 53 mills north of me, I was told the rpm is 16 and they developed 1.6 megawatts each.
2144.77 horsepower.
16 rpm
704,021 ft/lbs of torque.
For perspective the largest combine/tractor/highway truck engines are at 2000 ft/lbs.
352 times the torque.
Only 1/100th the speed though.
Yes, it would take a lot of oil to cool the gears!
Transaxial, BrianTee and dookiller like this.

Being honest may not get you a lot of friends but it'll will always get you the right ones.

And, of course, they wont fail on a calm day, they can only fail on a windy day and the windier the more likely.

You mean like a combine never breaks down just before a rain?

Actually, last fall I had a def fluid "quality sensor" crater, ate a rock that completely destroyed the feeder chain and it started to rain, (three day shutdown) all within 1/2 an hour.
The quality sensor was about to put me down to 1200 rpm and 50 horsepower or so by itself.
Mark on the wall material!

Add about 20% because of gear and generator efficiency as that is the generated output power/746 watts per horsepower. An incredible amount of stress and energy - from wind!

Incredible stress and is there not much larger mills, 5 MW somewhere on the ocean just off the coast of England?
