This gizmo reminds me of an "invention" back in the 70's that you tapped into your furnace fuel line. It supposedly injected water vapor into the fuel to save money. A good friend then was trying to start a dealership. My dad liked him and bought one,....lol, we had some chuckles about that thing in the furnace fuel line. I have no doubt some think it saved fuel.
Funny, this one tries to do the opposite, but I don't see it happening either. I do see it selling though.
