I don't believe he's learned or done anything other than how to bolt cable to terminal. He only pretended to have done something extra, and it was predicable that he wouldn't supply any details. It's classic ghinius weaseling. He once claimed to have designed his way out of "needing" AC in a very hot climate. I nicknamed his invention "Magic Mass". Daestrom called him on it, and George took the discussion to email to demand a signed non-disclosure agreement before getting into details. But Daestrom outed the whole thing and George never did give so much as his average daily outdoor temperature, or even say what interior temperature constituted "not needing" AC. Hilariously transparent then as now.
What he expects is that most readers won't be able to tell if he's lying. He probably believes that only a few on Usenet know better, but it's likely that even the least technical folks he's ever dealt with were able to see through his bluster. For example, anybody with a pocket calculator can figure out that the following Ghioism is a foolish self-busting exaggeration: "my petrol use is, as it has been for many years, an average of twenty liters per fortnight. The bulk of this is for the motorcycle which is used for transport to and from school (280 KM a week). The rest is used to run the tractor, chainsaw and of course the generator"
Actually, he's long since gone on to pretending to be something new
Reminds me of a story. I once asked a day helper if he knew how to operate a nail gun. He assured me in no uncertain terms. Minutes later he drove a pair of 3" nails through two fingers. Some people just aren't smart enough to admit what they don't know, even when it's against their own interests to pretend otherwise. There's surely something that George could be trusted to do, but even if it was augering a toilet drain I'd be asking myself how many ways he might find to screw up the job. It would take a brave owner to let George Ghio near a large battery bank. After all, what could one say if things went wrong? "I knew he couldn't be trusted to operate an Ohmmeter, but I thought he'd be OK with 1000 Amps" :-)
Did you read his 300k Ohm wire foolishness, and realize that he bills himself as a "power consultant"? The word "design" doesn't fit in with such contradictions except in his imagination.
One more thing you've probably noticed by now. Often, and only *after* George has absorbed yet another thumping in a debate, he'll weasel his way out the door by using any silly dodge. In this case he's pretending to believe that you are Ron. At one point he claimed that I was actually most of the regular posters in the energy newsgroups. Of course, being a true Renaissance nitwit it's unlikely he's capable of reading a header, so the Phil-is-Ron thing could be yet another delusion.
