This is indeed a very interesting point to it! :)

And I think this is indeed why your interesting idea won't be very
practical.. :(

| I have an idea about a not simply decorative usage of the fiber optic "motor" (that's not the well known fact that it can be used as a sort of rotational sensor). BTW, as it's definitely not a motor, I'll call that part "fiber optic rotor". My idea (...) (25 years ago, 2-Jul-99, to lugnet.robotics)
