Sure, I've seen the seriously outdated website you've mentioned --- and I'm not impressed.
I've read Newman's book and I am impressed. I'm also impressed with the reports of those scientists and engineers who HAVE seen and tested the technology. Newman has described why you cannot simply "feed the output back into the input" since: 1) the system's commutator has to be very carefully timed and 2) Newman's biggest challenge has been to capture the back-spike while preventing it from over-charging the batteries.
Ample evidence exists that the system produces greater external energy output than external energy input. Newman is now using 400 watts input to power his newest energy machine which is mechanically coupled to a Grainger PTO conventional generator -- which according to Grainger Corp. requires over 3000 watts input just to achieve the required rpms to provide useful electrical output.
Newman then loads that PTO generator with another 1,000+ watts from TVs, lights, and fans.
Bottom line: 400 watts input and over 4,000 watts output.
Issue him his patent and let's get on with it.
