why does nobody do it on a large scale? There's countless videos on the net of people making 'tesla' machines out of simple components and doing things like, I don't know, charging their phone - without any cell. I would think it was codswallap if not for the fact that all the videos seem to have positive feedback, almost exclusively. Now clearly tesla knew how to get this energy, if he did indeed say he did; however if people actually know how to harness energy from the air, or electrostatic, or even wireless energy, then why don't they? I am probably just too guillable. But seriously, if Telsa said this **** can happen, I believe him.
