well, ive been making different versions of these things for a few weeks now because i got tired of wondering if it really works. My vids on youtube is a must watch to see what i mean. i absolutly can get combustible gas from water using one of these things and it cost me less than $20 for the material at Home Depot. Have i tried it in my KJ?, no Will I? Yes! My first vehicle though will be my old truck as it is carburated and theres less to mess up if something goes wrong.

What poeple do to save a buckscrewy.gif,that ends up costing them more in the long run.
ok then, sorry that i tried to help.#-o
Flair,
Please don't take my comments as an insult. I'm just skeptical of hydrogen produced by anything less than some sort of enterprise class process that will burn in your ICE and improve your gas mileage in a way which will be worth the cents per gallon saving.
So I got bored, I have insomnia, so I did a little homework on HHO.
The HHO theory:
An electric current is used to break the chemical bonds in water to separate the hydrogen and oxygen (electrolysis). That hydrogen is then combusted and the additional energy of the combustion of hydrogen is added to the energy from the combustion of gasoline, increasing your MPG's. Here's where I found some variation in the HHO theory. Assumption 1: The alternator in your vehicle produces more electricity than you need so you can use this extra free electric energy for electrolysis. If it didn't, your vehicle would stall every time you turned on another electrical component; OR Assumption 2: The amount of electric energy required for electrolysis is far less the amount of chemical energy obtained from the combustion of hydrogen. Or these assumptions are both used. The assumption that the oxygen needed for combustion is also produced with electrolysis, and that no outside oxygen is need. This means that this is a closed system, more on this later.
Scientific Law: The law of conservation of energy: Energy cannot be created nor destroyed; it can only be changed from one form to another.
An internal combustion engine converts the chemical energy stored in gasoline to mechanical energy. In the presence of oxygen, a spark is used for ignition. Ignition causes the gas to expand (mechanically), forcing the pistons down, turning the crankshaft, which eventually turns the wheels. (This reaction is quick, and the gases produced are ejected before they have completely expanded. So the theory that HHO adds more gas, or more heat making the gases expand more, or more rapidly, is false). This conversion of chemical energy to mechanical energy also produces heat, and light energy, which your engine does not use. So the mechanical component is the only useful component, and the heat and light produced are wasted. Only 30% of the chemical energy in gasoline is actually converted to useful mechanical energy. The other 70%, since it cannot be destroyed, is converted to useless heat and light.
This mechanical energy in turn, is used to spin an alternator, creating an electric field, essentially converting mechanical energy to electrical energy. There are losses here as well. Slipping and/or stretching of the belt, friction of the bearings, and wind resistance (drag) of the spinning components. The alternator efficiency varies by depending on the alternator, but usually has an efficiency of 45-70%.
Here's where the HHO assumptions come in.
Assumption 1: The alternator produces more electricity than is needed. For a second, let's assume this is true. If it is, and energy cannot be destroyed, only transformed, where does it go when it isn't used? Your alternator would be sending out lightning bolts if this were the case, or producing massive amounts of heat. Look at how much heat is produced by gasoline, which has an energy efficiency of 30%. If the were the case with an assumed 70% (best case scenario) efficient alternator, think of the amount of heat that would be produced when this "unused energy" isn't being put to use.
So your alternator doesn't produce extra energy. Where does the additional energy come from when you turn on extra electrical accessories (hint: it's not the battery, your battery is not used as a source of electricity while the vehicle is running. The battery stores electricity, chemically, for use when the alternator is not spinning.) The alternator gets its extra energy from the mechanical energy of the engine, robbing your engine of more efficiency.
Assumption 2: The amount of energy needed to break the chemical bonds is less than the amount of energy produced from the combustion of hydrogen. Remember, this is a chemically closed system with HHO, all the needed oxygen is provided by electrolysis. The only thing entering the system is the electricity. (If it wasn't, this would rob oxygen needed for the combustion of gasoline, which would cause less gasoline to burn causing your engine to run 'rich' and thus lowering efficiency). So you're breaking the chemical bonds of water, only to reform them. Remember, energy cannot be created nor destroyed. What exactly does this do? Essentially it converts electric energy from the alternator, into heat, which we already stated was USELESS in a mechanical engine!
its water and free.
For instance if the gasoline engine has an efficiency of 40% and the HHO system has an efficiency of 90% then the combined efficiency is increased to at most 65%.
In my limited knowledge of electrolysis I have heard that experiments were done on electrolysis and found that it takes more energy to create the hydrogen than is produced from it.
The efficiency may be increased due to the alternator already spinning (wasting energy). So it would be interesting to do an experiment and see if it actually works.
Normally, gas is wasted and has to be burned further in the catalytic converter. This catalytic converter is apparantly not needed in a HHO system.
It is difficult to just dismiss something as complicated as this without doing experiments.
But that's just it, flair, it's not free. There is an energy input required to produce the resulting gas. That energy input is quite significant if you want to produce any amount that will make any serious quantity of usable fuel.
So you must make some choices about what source of energy you're going to use for your input. If you use batteries, you have to charge them somehow. The only viable use of electricity to produce hydrogen is solar. Any other form of electricity is probably a bust because you might as well use the electricity at 100% efficiency instead of using electricity to create hydrogen, losing 50% of your energy in the process.
You heard right. This is why realistically, the only input that should be used to produce hydrogen is an input which is already going to waste-- the alternator is one theory. I have mentioned solar in several previous posts. While the sun shines, there is plenty of power which can be harnessed to produce hydrogen. The only question is, how many sq feet of solar panels will produce how much hydrogen? The answer is usually a lot to get a little. I submit that the alternator would have to turn quite a bit to produce a very small quantity of hydrogen.
Believe it or not, everything does not always need an experiment, sometimes it just needs some calculation. To quote the great Nikola Tesla:
"If Edison had a needle to find in a haystack, he would proceed at once with the diligence of the bee to examine straw after straw until he found the object of his search. I was a sorry witness of such doings, knowing that a little theory and calculation would have saved him ninety percent of his labor."
A simple running of numbers with some knowledge of your inputs and outputs are all that's necessary. It can be easily calculated how much hydrogen can be produced through electrolysis with i amount of input over t amount of time.
Here's the thing on that. "I heard of a guy; I met a guy; I know this guy" really pales in comparison to the fact that GM is closing down, what, three manufacturing plants, posting record losses and having to rethink their entire business process because *surprise* their cars are too thirsty. Despite all the conspiracy theorizing, it is in the best interest of the car manufacturers to produce a high mileage car. There are manufacturers, right now, who are putting everything they have into producing a high mileage car. And guess what, it's frickin' hard to do.
The smallest car on the road, bar none, is the Smart Car. It's a two seater with almost no cargo capacity. It gets a combined mileage of 36mpg. 36mpg. Let me say that again, 36mpg. Toyota's fantastically popular Prius, a marvel of technology using (sorry, hate to repeat myself) electricity DIRECTLY to produce forward motion, not indirectly to produce hydrogen, then use the hydrogen to assist forward motion-- therefore suffering no loss of efficiency from the produced electricity-- only gets a combined mileage in the 40mpg (real) range. the point here is, that these cars which are the models of high mileage, get a little over twice my combined average, and maybe...maybe 3x my combined mileage, respectively.
If I were to sell my Jeep at its current value and buy one of these vehicles, it would take years to recover the cost of doing so, even at the current high gas price of $4.21 for low-grade regular.
As the old adage goes, if it sounds too good to be true, it probably is.
I disagree. These are not vague theoretical problems that we have no math to describe. they are simple problems of physics: Energy input vs. energy output, how much energy (watts) does it take to move 1lb of weight... Adding a small bit of hydrogen to your ICE is probably not going to make any significant difference, and may actually hinder your performance through damage or cost.
