Well the answer is it is not possible. I am posting this as I am amazed at the number of views a video like this has.
These people I will not call scam artists, as they are not selling you anything. However they earn large sums of money from YouTube hits. In the thousands of dollars. You can find hundreds of videos like these. Good luck to them but as far as a free energy generator goes they are total BS.
I guess they are entertaining at least.
