My daughter and I built a hydrogen generator several months ago and I have seen consistent improved gas mileage of around 40%. I know I could go higher but I'm kind of lazy when it comes to tinkering around with mechanical things and 40% is still pretty amazing as far as fuel saving devices go.
Hydrogen Generators might sound expensive and they are actually, unless you make your own. What? You're no rocket scientist? You don't have the money? Well, you should know that to build yourself a hydrogen generator is way cheaper than if you were to buy a ready made one and no you don't have to have Albert Einstein's brain to do it either.
HHO gas generator is one of the most important components in the now famous water-for-gas systems. It is alternatively known as the Hydrogen generator. But what is HHO gas and what does it do?
