I am sincerely interested in seeing a production unit from a real company, not someone on ebay using cardboard and tupperware, that separates the hydrogen and oxygen in a way to only deliver hydrogen to the cylinder.
I know backyard engineers have been doing that for some time, as have I, although I saw better results in fuel economy savings by keeping the oxygen. So I don't think its necessary on low volume electrolysis units.
