In a nutshell, if I pass an arc through a bunch of gasoline I get pure hydrogen gas. I don't think so. Were assuming this is in an oxygen free environment. Hydrogen is an extremely reactive element. Im sure if it were in the presence of ANYTHING under such incredible heat it would not stay hydrogen. And what happens to all your carbon? it just turns into soot and stays there? Well thats not very practical, so it would have to be burnt (turning it into CO2) but that introduces oxygen. And o2 and H don't mix very well in the presence of "plasma".

Im tired, and that probably doesn't make sense. But don't believe anything just because theres a patent on it. Ive read plenty of patents that are complete crap. All it looks like to me is a bunch of large scientific words to make you think it makes sense. It doesn't. You cant crack gasoline into hydrogen with a spark and feed it into an engine
