my understanding is, everything uses energy, so if the machine makes a noise, that’s lost energy, heat, light, friction etc all the same. since its impossible to eliminate all of those factors its impossible to have perpetual motion – even if by some mirical someone worked it out, it would be useless as you wouldn’t be to generate with it as some energy would be lost in generation, therefor no longer being perpetual.
sounds right in my head but I’m no scientist 😂
