Hello ,if it doesn't move continuously then it is good as Noether theorem will not create any hurdle init.i would like to tell you that I will mounted two piston generator on both side of long tube to extract energy and this energy will feed a lever system to lift up the device again and again.if that input is free then why there is no free lunch? Friction,load is not problem, p.e. is being increased,input is almost zero , device is getting back its initial position without any extra energy , Noether theorem will not work here as it works only in continuous running devices then why?
interesting point is input as it is very minimal due to equilibrium position ,but output?
