Original Message ----- Mounting two magnets (separated) inside a non-magnetic coil spring (compression) so that the 1/R^4 attractive force can aid in compressing it when it's dropped from a height sufficient to cause it to compress slightly (thermal collision force aided by the Casimir force) should show some interesting bounce effects, albeit the coil spring is a linear device as opposed to the 1/R^2 repulsive electrostatic force between the atomic nuclei.
The bounce height compared to that of a similar spring with non-magnetic slugs of the same mass as the magnets should illustrate the point. --------- Magnets? I just recieved a link to a magnetic engine, looks interesting. http://cycclone.com/welcome/page2.php
