Well I made a few assumptions. Since we are in an automotive forum and the "Fuel, Ignition, Air, & Tuning" section specifically I figured he meant Hydrogen generators as applied to introducing the hydrogen into the intake of an automotive engine as a fuel. Since there is a TON of internet hype about this process his comment made me more certain, and since there are about a billion sites dedicated to this with varying degrees of polish and professionalism, it would be hard to pick one as representative of the idea as a whole. My pick was purely arbitrary.
Anyway, my point is: I don't think he had a specific "Brand X" hydrogen generator in mind, but I do think I am correct in divining the general direction of his inquiry.
Fair enough?:fest06:
