Hello to all! I have but 1 simple question: Has the secret of Nikola Tesla's ability to run a car on power from "the ethos" ever been revealed? Was it a permanent magnet motor the didn't need an external power source? I can see all the skeptics eyebrows being raised as we speak regarding "perpetual motion", but since he was not regarded as a charlatan or fraud, isn't that exactly what he did?? Thank you in advance for all replies!
