I know someone who spent real American money on a hydrogen generator for his Volvo. The ad promised 20% increased gas mileage... but it didn't do anything besides lighten his wallet. Go figger. I'll never understand how people continue to believe in bs back-of-the-magazine ads for THE INCREDIBLE SECRET DISCOVERY. Then again, this same dude started wearing magic crystal bracelets that his moon-howler wife said would make him stronger, smarter and keep him from getting cancer... or something like that.

If he'd only put on the moon-howler bracelet first, he would've been smart enough to not buy the H2 generator.
