It’s literally explained in the article what happens at almost 4x the speed you mention.

Is it? I can only find this:

> [...] this one is rated for speeds as high as 70 m/sec (252 km/h / 157 mph).

And the question was what happens above this 70m/sec. A Taifun might go above 83 m/s.

Do you mean 70m/s?

My guess is that power generation would be greatly reduced or constant after that. It can also be that the whole thing breaks apart, and therefore needs to be stowed in those conditions (we are talking about category five hurricane)

Sorry I meant 70 m/sec. Current designs feather the blades and stop spinning when they exceed their maximum safe wind speed. The article says that this design can handle a much higher safe maximum wind speed, but there must still be a limit, and what then? If I understand correctly they can not feather the blade to stop.

It seems an obvious question so they've probably got a good answer, but I couldn't find it in the article.
