Mr. Bill Fung suggested that if we change the simple falling steel ball experiment slightly, we could have very different results. Perpetual motion wheel similar to the Bessler wheel might be possible.
This particular video have the falling balls hitting hard surface on one end and a padded surface on the other. The rotation time increased from 2 minutes 35 seconds to 4 minutes and 55 seconds.
