Scientific dogma is worse than religious dogma. Permanent batteries are as real as permanent magnets.

  It's not dogma, it's a simple application of the null hypothesis, meaning until there's contradicting evidence, the assumption is that there's no effect. Extraordinary claims require extraordinary evidence. Without the null hypothesis, if we instead assumed extraordinary claims to be true without evidence, skeptics would be required to prove a negative, an impossible burden of evidence in most cases, and Bigfoot would become real by default. As things stand, skepticism is the default position of a scientist, and the burden of evidence rests with those who claim extraordinary things. > Permanent batteries are as real as permanent magnets. Neither a permanent battery nor a permanent magnet represents an expenditure of energy, or a violation of energy conservation.

    By permanent battery I mean a battery that can supply current indefinitely without needing to be charged. The second law is meaningless. It only applies to 'isolated systems' which do not exist in reality. "Truly isolated systems cannot exist in nature, other than possibly the universe itself, and they are thus hypothetical concepts only."

      > By permanent battery I mean a battery that can supply current indefinitely without needing to be charged. Yes, and there's no such thing. Also, they're not equivalent to a permanent magnet. > The second law is meaningless. Well, since you aren't here to discuss physics, have a nice day.
