This is the H2 generator that I constructed several years ago. It uses a chemical process to create hydrogen, as opposed to the electrolosis that is used in a HHO generator that produces hydroxy, or oxyhydrogen.
I have used sodium hydroxide, exclusively (as opposed to any other caustic sodas), with aluminum and water, with this unit.
I have tested it in the past, but have been busy with other issues and topics, so maybe this spring I will refine it a bit more, as well as finish some of the other projects that I havebegun, or have thought about beginning?
I have tested this unit on a 1988 Honda Accord, with a 2.0 Liter, carbureted engine. The Accord has had a slipping transaxle in overdrive, since I bought it used. The best increase that I have measured was an increase from an approximate high 20's mpg, to low 30's mpg, on gasoline alone, to an even 50 mpg, with the H2 and gasoline, while visiting family in Oklahoma and traveling to Texas to visit more friends and family. I am certain that there would have been a greater gain without the slipping transaxle.
I have also tested it on a drive from Kansas to Georgia. I noticed that there was quite a bit of an increase in the powerpand, while climbing the mountains in the Chattanooga, TN area. In fact, there really wasn't anything else on the highway that was able to climb like this POS Accord could.
It generally takes about 20 minutes to begin to produce any significant levels of H2 and it will produce a steady high output for an approximate hour to hour and a half, before it tapers off, due to the water depletion in the unit, so it isn't optimal for short or local trips. It is great for highway driving, however.
I haven't messed around with it enough to configure an automatic water replinishment system. The byproduct of the chemical process is hydrogen gas and aluminum oxide, or alumina. It settles in the bottom of the tank and has to be maintained on a periodic basis, ie. emptying the alumia deposit. I am going to try to incorporate an automatic system that will do that, as well as add additional aluminum, as I am able to work more on this unit.
It is large and isn't able to fit under the hood, obviously, but it does work. I was initially concerned with having a hydrogen bomb with no real cutoff mechanism (it is a chemical process, after all) in the back floorboard of the vehicle, but I did incorporate a system that would, in theory, prevent any flashback into the generator, in the event of premature compustion of gas in the engine compartment, or a backfire. Good thing. I was on another trip to Dallas, for a concert, and it started producing too much pressure and blew the shit out of part of the air intake and emissions controls, under the hood. There was no flashback. I'm still going to try to refine that process, as well.
