So if the energy is neither created or destroyed it is just a matter of finding a way to constantly transfer the energy from one form to another, and surely if we live in a system where the energy is not created or destroyed whatever energy we use is transferred into a different kind of energy which we could then transfer again and keep transferring the energy. So we do live in a system of perpetual motion, isn't that correct ? I'm no physicist, and I only just been reading all these comments and it's all interesting and people saying something is impossible because someone at some point said so and created all these law which have been proven to exist but does not mean that someone may prove that they are wrong. We live in a world where technology changes and improves everyday and what seems impossible at the moment doesn't mean that it cannot be possible in the future. I think the main point is that people should keep their minds open despite how impossible something may seem.
