FWIW - The same poster has put up a video or two concerning the Dzhanibekov Effect - which is fascinating in its own right - not well known, and possibly not fully characterized since it seems to demand more than one (and preferably three) interacting axes of rotation.
Veritas neglects to mention this oddball effect in the wind power situation, for the obvious reason that there is apparently only one axis of rotation which is the fan blades. ... but ... what if the a similar effect (to Dzhanibekov ) relates to having one major axis of rotation plus one or more truncated axes, which maybe manifest as vibration ? This relates to the spinning satellite with the whip antennae which will flip-flop...
