To be more specific: It takes more energy to turn the alternator to make the electricity to make the hydrogen in the "jar" than the jar can produce in hydrogen. The only way for it to be "cheap" is for you to manufacture it at home using very large solar cells and bottle it up for use in your car which would cost more than you would save in a hundred years. It's like ethanol, it cost more to make it than it's worth (right now.) In other words: they're fooling their selves. Sorry for the bad news.

Based on my research, I came to the conclusion that it may take more energy to make the hydrogen than it gives off when burned, however, the addition of the extra hydrogen and oxygen into the fuel/air mixture creates a better, more efficient fuel burn. This allows the engine to create more power more efficiently with less fuel consumption. The additional draw on the alternator is exceeded by the more efficient use of the already existing fuel source. A normal gasoline engine only uses like 12% of the energy from the gasoline it burns(I don't remember the exact %), but the same engine could potentially double its efficiency by the addition of the hydrogen and oxygen from the electrolysis of the water. This is not a creation of energy by generating hydrogen, it is the creation of a fuel additive that better utilizes the energy from the gasoline.
BTW - I haven't actually tried this because I'm not 100% convinced that it is safe and that it won't ruin the engine on my daily driver vehicle. So, someone prove me wrong if they can.
