Have any of you tried adding a hydrogen generator to your RV to convert the engine to a hybrid diesel / hydrogen engine? If so, what unit did you go with and what kind of mileage increase did you get?
I've read that you can pretty easily add an HHO generator to feed a stream of hydrogen in to the fresh air intake so that you burn less diesel and more hydrogen. You basically need water, a catalyst, and a small electrical current to do this.
I've found a couple sites such as this one in Canada and this other one in the U.S. that sell hydrogen generators, but I haven't tried this on any of my vehicles yet:
It seems like it would be neat to try. I was just wondering if any of you have taken the plunge and what results that you might have seen.
