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.
