This Hydrogen crap is alot like religion. They both require an amount of faith to believe in something which you cannot see or scientifically prove. They both cause controversy between "believers" and "non-believers". I think the "believers" somewhat resemble the mormons that harass me every time I happen to be outside when they ride by on their bicycles. One question I keep asking myself is this: Can someone name one vehicle that comes from the factory with HHO installed? Why is it that I only see "kits" on the market and not some factory assembly that was made to increase the mpg of the vehicle the minute it rolls off of the assembly line??
