Little Wheel Motor or Trevelyan Rocker Roulette

In reading about the ball bearing motor it became interesting to see just how much speed could be reached with only heat singled out as the driving force. The wheel is the base of a towel bar mounting post. The top half of the post can be seen in the upper right or in a previous video. The wheel weighs 190 grams and ran a little over twenty minutes.
No smoke and mirrors but it does seem that way. The platform is part of a revolving six-spoked/arm condiment tray with the holder and cups removed.

Unworldly magic! It should be a kinetic sculpture in and art museum!
