That is a beautiful article Auntiegrav, even though I am not sure how much to believe it, I so hope its true. I will keep my eye out for evidence of it being true or false, There are a couple of reasons I suspect it; the author of it seems to have very in depth knowledge in some places, but not so much in others. They described the structure of hydrogen, and the process of electrolysis, calling it a brown generator in keeping with the definition of brown hydrogen. But the part about the electronics picking up the oxygen sensor, and using that to control the PWM of the electrolyser - construction of a controller like that, and the onboard PWM power electronics, tricking the in-vehicle engine management system that would normally use the oxgen sensor to allow the engine to keep working, would be a challenging task, even for a professional hardware engineer. Older engines, (ie with carburettor as opposed to fuel injectors), would not have an oxygen sensor to my knowledge. If they actually did this, they are either professionals, or in the wrong job. I couldn't quite understand how they managed to interface it with the fuel carburettor or injector, using what looks like a piece of garden hose either, But again if they really did this, then they must be genius level "Badass" Engineers. It's way more than I would ever have been crazy enough to try, so my hat would have to be off to them if they really did this and it actually worked :)

On the refuelling interfaces of existing hydrogen vehicles, lots has been done, they are pretty safe, no accidents so far, despite lots of fleets of them doing lots of miles. I have a paper describing this, downloaded from some site earlier today, I can't find the link now where it came from, but if it shows up, will include it in a future part of the system modeling story set.

I agree with you - more research by more people is always good, hopefully without any serious accidents :)
