If it does work, I would try it. I love building stuff like this. I should show you guys the Tesla coil I built in HS. All homemade. Only thing bought was a neon sign transformer. The thing shoots out 8-10" sparks, about 250,000v. Wonder how the digital camera would work near it? I know it totally wipes out the AM radio band while running. You can hear it sparking over the radio.

Maybe I need to design a nuke powered hydrogen maker.

BTW: I bet the guys selling these plans/kits are making some serious cash now.

Hahaha. Yeah right Kent! What do you know about nuc.........

Wait.....

should work, how did you hook it up to the engine? (pictures!)
i am building one for my crappy van too, hopefully i can get it to work hehe.

Just to one of the vacuum lines, I doubt I could get a good picture of it, but I'll try.

Good luck with the van.

Kent's point about the hydrogen somehow helping to burn the gas more efficiently does have some merit and it is worth looking into for our rotaries. But it needs to be done with careful unbiased mpg measurements over a wide range of driving conditions for at least several weeks comparing both set ups.

Concerning feeding the hydrogen through the vacuum line, won't this in effect create a vacuum leak? If so that would probably more than negate any advantage even if there were more efficient combustion with the H2.

Don't think it will act as a vac leak since it is H2 (and maybe O2?) that enters instead of pure air. Haven't looked closely to see if they dump the O2 or burn it too. Some say that the vac helps to produce the H2 and O2 faster. I don't really believe that. What happens is the vacuum causes the bubbles to expand so it looks like there is more gas generated (volume), but the mass of H2 being generated remains the same.

I also wonder how much H2 you need to inject to complete combustion. Nothing is really being metered, so it is a guessing game based on the design, the amount of minerals and crap in the water, how much baking soda added, etc. The production rate also remains fairly constant, but your gas/air use is going to vary. I suppose that as long as you generate enough H2 to complete combustion, any excess will probably be converted to water vapor or excape and not really matter.

Anyway, it looks good on the surface until you dig a bit deeper. There are certainly holes in the logic. Maybe it'll work and maybe it won't. It'll be interesting to see. You do need good documented MPG calcs (with and without the system) over a long period as Ray suggests in order to prove that it does anything, though.

Remember that H2 is a very tiny molecule. It will leak if you're not very picky about the materials you use. Also, here's a fun link for you:

Changing your driving habits will do more for your gas milage than these "hydrogen generators". But I don't remeber buying my 2 RX7s for fuel mileage. That's what I have my BMW and Lancer for. If you want fuel mileage go buy a Honda Rebal. My wife's gets 70+ miles per gallon

Read through that website before you waste anymore money.


I think it should be made very clear that the Hydrogen powered RX-8 and other vehicles Mazda produces have absolutely nothing to do with this scam; they run on pure Hydrogen produced elsewhere.

Rotary-Celica

and another site http://www.geocities.com/midimagic@s...t/hydrognk.htm


The device that connects to a car generator and produces hydrogen from water supplied from an accessory tank will use more gasoline than doing nothing to the car. The ENERGY PENALTY happens in the car too. It takes 60% more energy from the car engine to make the hydrogen, compared to the energy that same hydrogen could possibly add to the energy of the engine as a fuel. So you get fewer miles per gallon.

This is almost as good as the magnet that improves gas mileage by up to 15 mpg.

United Space Alliance....... or NASA, has a hydrogen powered rotary on display. Pretty neat.

props to the OP for experimenting. Fyi hydrogen powered and supplemental hydrogen are 2 very different things.

You wanna know how to really improve your rotary's fuel consumption?










Buy a piston powered beater.

That site misses the point. The hydrogen is not used to generate power but to act as a catalyst to encourage complete combustion. I'm not saying it works, because I seriously doubt it does anything worthwhile, but the concept, in theory, is a sound one.

Isn't electrolysis a really slow process? I can't see it being made quickly enough inside the bottle to even be beneficial without all the thermodynamics laws involved.

Their site shows a Home Energy Station that uses natural gas to make it while helping to heat and power the house. There's also a solar station in the works.

well we shall see if he gets any improvement in gas mileage. besides the more miles you get the more fun you get to have!!! i have a miata but it is not as fun as my fb.

Uhmmm...wouldn't you want to add O2 to the mix to get a more complete burn? If you just add H2, you're going to be adding more fuel, but not more oxygen or heat to help the burn.

Remember what you need to have a fire? 1. Fuel, 2. Oxygen, 3. Heat, if you remove one, or get one out of whack from the others, you won't have a complete burn.

If you would add O2 though, you're going to have to meter it, otherwise you'll have a nice little bomb (prolly just a preignition knock).

That's just me though.

Oh, how about making a rotary run on alcohol, like ethanol, it should work, unless there's a lot of rubber along the way.

What I find odd, and no one has commented on this, is with inefficiency of our engines and all the unburned fuel that goes out the tailpipe, wouldn't it make more sense to add extra oxygen instead of hydrogen to help burn more fuel? Adding hydrogen could rob the oxygen needed to burn the fuel mixture, leaving even more unburned fuel going out the tailpipe.

Granted, I may be totally off base, I'm just tossing a thought out there for those who understand thermodynamics/physics much better than I do. We can also run our engnes leaner than the stock carb, providing we can deal with the extra waste heat generaed in both the engine and the exhaust
