Friction is a loss of usable energy. There is no such thing as a free lunch.If you look at Newton Cradel and how it works, now if you replace those balls with say newtrons the whole system changes in a new type of theory.It becomes more of a thermalization of friction. If you take the thinking to a quantuin area I can only guess what will be found.When thermal equilibrium is achieved no more work can be performed through thermodynamic processes as a temperature differential does not exist to drive those processes. From a thermodynamic standpoint the system has reached maximum entropy and disorder.
