You could, but would it be economically feasible, considering you have to pay for the electricity to split the water.

Based on that, 1 gallon of water is 210 mol of water, consisting of 210 mol of diatomic hydrogen and 105 mol of diatomic oxygen.

210 mol of diatomic hydrogen weighs 420 grams, so with a density of 0.08988 gm/l at STP you get a volume of 4673 L, or 1234 gal, at STP. So one gallon of water has 4673 liters of diatomic hydrogen in it, at STP.

As intriguing as it may be, YouTube is not a very good place for "research" IMO. There are just as many B.S. videos anywhere on the net as truthful ones. I'd prefer to stick to what I learned in Chemistry and Thermodynamics in college.

Sure, it's possible, but hydrogen is a terrible fuel for an internal combustion engine originally designed to run on gas because it holds a lot less energy than a similar amount of gasoline will. Engines converted to run off of hydrogen make less power and get worse fuel economy because of this.

Plus, your electricity bill would go through the roof since you'd be paying your fuel bills to the electric company instead of the gas company. Add that to the fact that electrolysis can be relatively inefficient, and you have a recipe for pain. Why not just have an electric car that plugs into the wall every night instead?

 

I'll just stick with propane then. Lol

 

I really don't know if this is accurate. This is exactly what United nuclear is doing. They just started their production again because they finally found a way around some law....

http://www.switch2hydrogen.com/

They manufacture the hydrogen for themselves and use these special tanks that don't hold gas or liquid H2 (read about it, its pretty cool)

But i have followed this for a while and it didn't really progress for a couple of years. Finally they updated the site with a comment in September.

I think everyone here is overestimating the amount of energy required to produce H2 through electrolysis. They use a 400w 48v dc current. That is only 8.3 amps at 48v....

And don't say "it's a scam too".... They don't sell anything (yet) and haven't for years. They don't take money from people to help in the process to come up with this. They fund themselves and develop it for themselves. If 5 90w solar panels could produce enough electricity for electrolysis it wouldn't require that much electricity. (your electric bill shouldn't skyrocket costing more than gasoline originally did)

Another really important detail to point out
check out these tanks
http://www.switch2hydrogen.com/h2new.htm (I think that this might be what was holding them back, the update on the left side of the home page doesn't go into much detail but does mention chemicals used in storage)

 

very interesting. I'd like to see what they do to the engine.

 

wait and see i guess!!

 

The point is not how much power it takes to create hydrogen (you can do electrolysis with a single 1.5V AA battery if you're so inclined). It's the total energy stored that matters...

So say for their case a 400W system is storing hydrogen in tanks at 90% efficiency. We won't even look at the power required to pump the hydrogen to pressures needed to liquefy it, but just the stored energy going from water to H2 and O2 gas.

One gallon of gasoline holds about 119,000 kJ of energy, so for 360W of input power (400W x 90% eff.) it would take 91.5 hours to store that much energy. 91.5 hours, for one gallon of gas.

Say you were making H2 at home, and wanted to store as much energy as 3 gallons of gasoline overnight (6 hours) to get to work and back the next day. Not including pumping to storage pressures, you'll need a total of 356,000 kJ (about 100 kW-hr, don't know the rates at the electric company but anyway). So figure 90% efficiency, you'll end up paying for about 397,000 kJ of energy. To get that much energy in 6 hours, you'll need a total power input of about 18 kW (18,000 W). 18kW of draw, for 6 hours, to store the equivalent energy of 3 gallons of gasoline.

 

They don't liquefy it in these tanks. They use some sort of scrubber. From what i understand the hydrogen is mixed in some weird sort of chemical and scrubbed out (kinda like a rebreather, only this actually stores something as well)

BTW i just found where they mention basically somehting similar to this HHO thing on there

I couldn't find that last time i looked for it, but i just did. Of course they are mentioning stored (manufactured) H2 gas, not producing it from the vehicles electricity.

 

We've already gotten past this ...

OF COURSE if you add a flammable substance to the intake charge you will reduce your fuel consumption, there is NO question about that.

The point here is that you can't do it by running an electrolysis cell in the car.

 

This whole thread is hugely entertaining from a sociological observation standpoint. There seems to be no end to what the human mind will convince itself to be true.

This thread is a case in point of what happens when a country reduces the number of engineering degrees awarded and increases the number of law degrees awarded.

"The world is flat!!!" John Birch lives!

 

here are 2 links that can really help you out.......

1st is the hho booster

2nd is for the o2 sensor

hope this helps out anybody that is lookin

 

You know, the idea of converting water back to gas was to "supplement" the gasoline. It's not to replace gasoline. It's suppose to makes it burns more efficiently. I think some of you missed it and argue that it won't work based on the wrong assumption.

 

All I have to say is at one point in time the world was flat, humans could never fly, horses were the only way we could get around, you couldn't talk to someone around the world, space was impossible to get to, we had to salt and smoke all of our meat so it wouldn't spoil, and earth was the center of the universe. I'm not saying this will work but I do think that a lot of people out there think that we have learned as much as we can learn about the engine and many other things, it's just not true. heck less then 15-20 years ago the internet wasn't even around for the average joe, we still did all our research by reading books, crazy.

 

Your engine is ALREADY burning the gas it's taking in, that's what an oxygen sensor is for. A little Hydrogen added from an electrolysis jar won't help that...

This scam has been around for more than 30 years. Perhaps you could explain to me how there isn't one single valid documented case of it actually working as advertised in ANY vehicle anywhere?

This isn't a scientific revolution that's being suppressed, it's a festering boil that won't go away because EVERYONE wishes they could get double their mileage for free. Unfortunately for us, it can't be done with a jar full of water and some wires.

 

I wonder how many people who think it should/could work actually passed high-school physics? There's nothing mysterious, miraculous, new, or high-tech about this. It doesn't take a PhD in physics to understand all of the mechanisms at work. There are no secrets being withheld from humanity, except that education is a wonderful thing.

Ignorance is bliss, I guess

 

Yup, it's just producing hydrogen and oxygen by the electrolysis of water.
No big deal. It's been done and known about for a zillion years.
Browns gas, HHO gas, geeezzzz like this is something magically and mysterious.

Wish I had a diesel. Toyota, of course!

Thanks for the read fellas. Alot went over my head (watched the girls in science class....), but my wife and I were just talking about all this and well.....I guess a few questions got answered.

Wish I had a diesel.

 

I thought that electrolysis split water molecules into the seperate elements hydrogen and oxygen and doesn't create this new molecule DHMO? I also thought that people call it a number of things, like HHO, HOH, hydroxy gas, Brown's gas, but that all the names refer to this split up state (so to speak)?

If someone knows more about chemistry here please educate me and point me to some info that doesn't look like scary fake counter-information leaked by the Department of Coorporate Corruption. No offense eric-the-red, that link is strange; I never knew athletes shot up the stuff or that some people think it can improve their marriage! Like spanish fly I wonder...And what the heck is "friends of scorched Earth?!" That doesn't sound very friendly at all.
I like the Earth.

I love the internet but figuring out what is good information and what isn't while perusing it is a real skill. I'm finding that doing research on this is a real challenge, but interesting...I grow more interested in this and in physics in general the more I read...I am finding myself reading textbooks for fun...
Anyway, excellent thread

 

Guess I should have read more of the thread before I posted that last one-I think I answered my own question.

 

Thats a joke right?

dihydrogen monoxide is often written in its chemical formula, H2O, or, known by its common name, water.
