37 m/s

That’s 133 km/h! That’s fast, imagine the pull on the rotor, and then combined with the pressure from the wind.
It’s also funny the rotation is faster than the wind speed, because cutout is at 31 m/s.
I know that when sailing with old fashioned sail, you can also sail faster than the wind speed. Still it’s a bit curious.
It’s also impressive IMO that they can build it to last 30 years.
