Okay then, so that guy ether spent a lot of cash on a HHO system that didn't work, or just likes to be ignorant.
The improvements seen with HHO, are to my belief, from better combustion of fuel droplets, higher O2 levels, and some steam (but that's really a different topic). If you ad acetone to your gas you will see less of a gain from hho. If you rig up a fuel vapor system you will see much less gain (if any).
But adding gaseous fuel to your engine will generally improve FE even when you consider the BTU's of the added fuel.
A good HHO system will have an eff of about 80%, but then you factor in the alternator, and the power given back by the ICE and you have very little return, so, yes, anyone who has taken a elementary school sci class can deduce that this ether doesn't work, or there is something else going on. I think the latter, as I have hear it from reputable sources (no one with good testing equipment, but people who don't have anything to gain by lying ether).
