The falling weights don't
supply any energy. If the machine were to run it would only move potential energy from one weight to the next. There would be no production of energy. The machine will not run because energy is lost in the friction of the machine and that consumes what ever energy you put into it to get it moving in the first place. Again, the Second Law of Thermodynamics states that "in all energy exchanges, if no energy enters or leaves the system, the potential energy of the state will always be less than that of the initial state."
