A smot dosnt have to loop to show work being done.We would only have to show the ball come to rest outside the smot [i.e., outside any magnetic-field trap],at a higher level than it started at. Previously I agreed, but a few hours later I thought of a potential problem with that. Consider two disk neos. One on desk with N up, the other PUSHED onto the first with N down. Now let go -- and the second flies UPWARD, to a higher level than initial height. It was in pushing the neos together that potential energy was stored -- like squeezing a spring. Let go, and you get kinetic energy - and in this case, a RISE in height. Self-looping for hours gets around the problem of a hand PUSHING the object into place, i.e., storing energy using muscle power. Count me in for a donation on your SMOT prize, Chet, IF it achieves self-looping...
