> The GE Haliade X, smaller but not by a lot, maxes out at 7 rotations per second

I think you meant per minute.

Per second would mean that the rotor tips are travelling faster than SR-71.

Although I'm glad it's not reality, the imagery of a massive wind turbine whizzing around at 420 RPM is pretty amusing

> Regular turbine spotters judged that the best sound balance was usually to be heard from within large concrete bunkers some thirty-seven miles away from the wind farm, whilst the engineers themselves operated their turbines by remote control from within a heavily insulated spaceship which stayed in orbit around the planet - or more frequently around a completely different planet.

Hehe, just to let you know your effort wasn't in vain, I got that.

Yes. Thanks.
