Thanks for reply, Yes, Say both contact points where "Diamond Plated" the closest you could get to zero friction, because if there was zero friction they would be no energy loss? Ok how about floating a Magnate Sphere over another magnate, that would work a hold lot better, For example: if I build a room from North charged Magnate & put a South charged Magnate Sphere in to it, in theory it should float in the middle, equal presure from all side would cancel each other out? the energy I spin the sphere with would take an extremely long time to leave the sphere, Perhaps years. I noticed once where I closed the door behind me, I'd a set of keys in them, one key in lock the other hanging joined by key ring, I noticed later on that evening that the bottom key way still moving, that what got me thinking of how to store energy in objects?
