According to the laws of Conservation of Energy, there can be no such thing as a perpetuum mobile of any kind. The purpose of this topic is not no disprove them in any kind. But then i began to think: A battety re-charger is powered by a battery which in turn runs the battery recharger. This theory alone will of course not work, but as in all sciences we have the "what if" variable. Lets say we make that circut frictionless and but it into complete darkness in absolute vacuum at 0 K. Would that run forever? (Of course there is not absolute vacuum anywhere in the universe) What part of this line of thought is inaccurate from my part? And how about Big Bang, was energy created there? Energy must surley have come from something in the beginning?
