The fly wheel is as close to this concept as we can get. The problem is that for an almost perpetual system to be worth engineering and building, we would need some way to use/remove energy from the system. A fly wheel will spin for a long time with current technology used to reduce friction, but who is going to pay for it to be more and more efficient if it's not going to do any work? And doing work is removing energy from the system, thereby making the whole adventure obsolete.
