Or a much, much better and provably valid way to do this - that is, spread the peak load more over the driving cycle (of an resultantly scaled-down engine) is to use a hybrid drivetrain (batteries acting as the power reservoir when max power is required).

BTW - anyone know how leaned out an petrol engine can go when mixed with syn-gas (70% CO 30%H2)? ... I'm thinking that Charcoal could used to make Water-gas off the exhaust heat (say, on an artic)?

First off, a car that has an engine that produces 250 peek horse power is doing so at the top of it's revs, not the most efficient speed for it to be running at, at those speeds is where you will often find it to be 10% efficient or less, it is more common for a gasoline engine to be tuned for peek efficiency to be around 2,000 to 3,500rpm and depending on the engine might only be putting out 35hp to 50hp (if it's the 250hp example), now you want to put a 5hp electrical load on that engine? over 300 amps on the alternator, an alternator that has a peek output of 100-120 amps, so you put a 300 amp alternator on and that alternator puts closer to a 9hp load on the engine, based off what a gasoline generator takes to put out 300amps at 12 volts continually.
Why are we still talking about this again? if you are someone who really thinks this can work then go ahead and try it, but if you put a device like a vehicle that also has a scanguage on that tells you real time mpg, you will see your mileage go up when you turn the hydrogen device off, it's just that simple!

Oh, hi UFO,
Well, yeah I left quit a bit out. If your only problem is getting the lean mixture you only need a new engine controller and ignition system. These are available at the ecomodder shop. In the Unicorn Corral aisle.

I meant there are more unicorns than blog entries on Ecomodder.

Can we just agree HHO is pish ?

Although I fancy one of those science museum kits for A- Jnr this holiday

Hey Mort.

Answer me this...what is gasoline??? What chemicals make up Gasoline? What is the main element? What elements are in the air the engine uses?

What are the main elements of water?

Now, can you put these 2 things together in your mind? The main element in Gasoline is the same element in the water you wanna use for fuel. So in effect, all you are doing is adding a tiny bit more fuel to the engine with an HHO generator. You still need 14/1 fuel air. No magic bullet because the fuel used to be water instead of gasoline.

HHO IS 100% Unworkable. 100%. No if's, and’s, or but’s. The claims made by people, like the claims you made in your post, are all based on blithering facts that do not relate to the real facts involved in a combustion engine. To ignorant people who don't know better it sounds reasonable. But to those who do know better, it is like you’re saying, "I had 3 fish for dinner last night and my son is 6 years old, and since the water in the toilet goes down the drain in a clockwise direction, this HHO Generator can improve mileage by 100%!"

...and genuine Unicorn "road apples" are pink, not the usual horse green, due to their rarity (rare, medium, and well-dunned).

You'd need a lot extra O2 to burn that mix (both for the H2 and the CO), so you're not leaning it out, but enriching it with fuel.
