My dad used to work as an electrician at the "Wind Research Institute" in Romania, back when the communists were still in power. So of course, I was regaled with all sorts of stories on wind turbine deployments all throughout childhood. One of them was when this huge vertical axis turbine research prototype suffered a destructive failure while he was in the control room underneath because of a flaw in the emergency braking system. Apparently, when the blades (that normally are under tension) break off they make a loud noise and having that thing fall on you is super dangerous. Only mildly related, but thought I'd share since only now, as a grownup, I realize it's actually interesting, whereas as a small child I really did not appreciate it. And, well, not sure how many times vertical wind turbines come into discussion. Can't wait for my kid to roll his eyes at my stories.
