Our Sunbird place is near the Palm Springs area, where there are thousands of windmills. On windy days, you can see the kilowatts generating, but whole sections of the farms are still, being stopped either for maintenance to protect them from excessive wear, or not necessary for current power requirements.
Yes, wind farms frequently seem to have put the doggle back in boondoggle. The ones on the Maalaea ridge allegedly generate 192 gwh per year, but I see a lot of them just sitting there idle even when the wind is howling.

I hope the Infinity Celebrity has a different captain with those strong winds coming.

What do the feathers do?

Feathering a propeller or fan blade means turning the leading edge of the blade into the wind so the prop does not turn.

Yup! Without prop feathering capability, this is what happens when you lose control of the wind generator during a high wind event. The photographer in this case was either very brave/stupid or a very long telephoto lens
