We just got back from a Caribbean cruise.
There are a sh*tload of windmills on Aruba.
The day we got there the wind was blowing like crazy and NONE of them were turning, LOL.
That’s the deal - when they actually would be the most productive, they don’t/can’t run them because they will either tear themselves up or make too much noise.
Yeah, what is that? I’ve seen windmills all over PA and even in a stiff breeze they aren’t turning. And I’m talking about 20 or so. Isn’t wind supposed to make them go around???????????????????
Actually that is fairly common. Too much windspeed will damage windmills, so they have a build in "self-protect device" that changes the pitch on the blades so they can't spin, or even a brake so they don't destroy themselves by spinning too fast (and causing damage) in high winds.
