Answer to WaterBearer's question.
Hi there, WaterBearer,
I think that I may well be able to offer an answer to your question. I've been researching "Brown's Gas" recently and found this thread during one of my research sessions.
I suspect that the guy you are referring to who has a torch with a 'cold flame' is George Wiseman of Eagle Research.
He can be found (sitting next to one of his commercially available electrolysers) at http://www.eagle-research.com.
If you spend some time exploring his site, you will find that he goes into great detail about the properties of the gas generated by his machines.
He also explains the maths behind running a vehicle purely from water.
Further delving into his site will also reveal mention of an effect that he refers to as 'Hyper Gas'. He claims that this is the propensity for one of his systems to spontaneously start spewing forth much more gas per Watt than is possible under 'normal' conditions. He does also explain that this effect, although witnessed a number of times, is difficult (or impossible) to reproduce on demand.
This leaves me with the thought that it is possible that Stan Meyer may have found a way to cause this 'Hyper gas' effect on demand and was merrily producing Brown's gas above 'unity' (more kw out of the system than is being put in to convert the water to gas).
Stan Meyer took his secrets to his grave. It's for the rest of us to experiment to find out what his secret was.
Did he know something that we have yet to discover (something not fully described in his patent) ? Was he deliberately conning us...? Or was his secret that, although he could produce the effect on demand, he really hadn't much of a clue as to exactly why ???
George Wiseman of ER is probably likely to find the key to above-unity gas production before the rest of us mere mortals, yet he's not shy about letting us all have a darned good attempt at trying to beat him to it.
Brown's gas technology is firmly in the public domain and George Wiseman's claim is that he is working to keep it there.
I hope this helps.
I hope we find the key to above-unity BG production. The world really needs it.
