There is also a follow up to the veritasium video on the wind powered vehicle involving a $10,000 bet. https://youtu.be/yCsgoLc_fzI Harry On Mon, Jun 7, 2021 at 11:57 AM Jones Beene <jone...@pacbell.net> wrote: > 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 ?
