Did the cathode also corrode, or just the coin?

[fundash]

I tried this, and my 9v battery heated up after running it for about 10 min, is this normal? is there to much salt?

[engenhocas]

after the electrodes are gone you get a white past what is that white paste aluminium oxide(Al2O3) or aluminium hydroxide (Al(OH)3).i think its aluminium oxide because the electrode is being oxidide but im not sure.sorry for my english im from portugal

[pyrorower]

Actually I think that it is in fact aluminum hydroxide based on your description. Aluminum oxide still has a metallic aluminum color, while the hydroxide is white and basically insoluble when it is pure.

[sharlston]

ISNT THIS SHORT CIRCUITING A BATTERY?

[knektek]

No. Because the water acts as a cap bank. Salt water is conductive but it is an electrical resistor.

[Wareagle]

 no.  the two metals aren't touching.

[sharlston]

but salt water is conductive

[Wareagle]

 yes but the electricity is having to go through that  salt water and that is where the work is done, splitting water into HHO.  not being sent back to the battery.

Can electrolysis be done for chromoly steel (4130 steel)? It contains similar hazardous elements as stainless steel, but not as much.

[sjs229]

 don't know ! :(

[sjs229]

 its an year yay!

If I may, I have been experimenting with electrolysis for quit some time. If what your after is the hho gas, to run a motor of somesorts, then you wouldn't want to use any salt, at least not chloride salts. I have had good results with baking soda,(sodium carbonate) won't leave you with caustic mixtures, also if you have trouble getting good graphite, use stainless steel. you can find it at your local hardware store for cheap, ie: bolts, switch plates are good. Anyway, just some suggestions, if you have any questions, feel free to ask me, I have been able to make a couple cars work with this method.

[bylerfamily]

This is not for a car,this is simply for fun...

[durai_412]

can you exactly tell me the procedures to run a car with just this process.. is it possible.

[l3nnz3]

Well, first you have to make something much bigger than that. just to be clear, what you will be dealing with is a big "bomb" essentially. With that being said, A piece of 3" PVC, PRESSURE RATED, don't exceed the limit, I also used stainless steel wall plates, you want to get the solid ones, no holes. nylon spacers, bolts and nuts, be creative. the closer the plates are to each other, the more gas is produced. you want to stack them alternating polarity, six wall plates to a stack, as many stacks as you can fit in the tube. But don't let them short each other out. I also devised a way to use stainless steel threaded rods to connect everything. Then you need essential safety gauges, ammeter, pressure, temperature gauges,etc. And a flashback suppression system, I made a smaller container out of pvc, put water in it about 3/4 the way up, doesn't have to be very big, about half to 2/3 the size of the generator, run the gas down into the water, and exit the suppressor, and into the motor. That's where it gets interesting. If it's and older car, and by older i mean no computer, it's easy. make an adapter for the carb. If it's a newer car, that has a computer, the programming has to be adjusted. Older cars with smaller engines are the easiest by far, also lawn mowers, go karts, anything that's carbureted. Don't blow your self up. normal flashback suppression, say like for an acetylene torch doesn't work on hydrogen, and what your actually making is Browns Gas, wikipedia it before you go off constructing and be aware of the dangers. It's not know for it's stability, but with a little caution, and some thinking most danger can be avoided.

[durai_412]

thanks for your reply but can you actually sent me a detailed report for it.. and what is the cheapest means for me to try it.

[hoihoi151]

 from my point of view you would be stupid to put hydrogen in you car engine. yes it can improve fuel efficiency but unless u change the timing of the spark plugs and basically do a overhaul of the engine u are going to be back firing hydrogen. get a big enough hydrogen based backfire and u could end up blowing something up. hydrogen ignites with a lot of ease. between 4-75% mix with oxygen. petrol is 2-6%.

in short. a petrol + oxygen doesnt mean explosion if the mix isnt just right.
hydrogen + oxygen means u have a bomb. so if u do attach this to you car be make sure NO oxygen gets into the fuel tank. and hope if u crash that the tank doesnt rupture.

It depends on where your located, and the means/funds at your disposal. For instance, if you are in the states, and can drive, your best bet would be to go to home depot/ lowes and shop around, get some ideas. That's what I did, along with alot of research. I can't tell you how to build mine yet. I'm waiting for patents to come through. I recommend research of atleast the following, the reaction occurring, including any chemicals you add, which if you want any efficiency, you will have to. and ELECTRONICS. amperage is what causes the reaction to occur. The first generator I made, was built from parts at Home Depot for about $30 US. But that was when it was still in testing, I didn't want to waste money having metal custom cut to find out it didn't work. I'm going for clean and safe, so i used baking soda for the added molecules, it's called a catalyst. and stainless steel, depending on the grade, resists corrosion and is fairly cheap where I am. I also didn't have a spare car battery at first, so I used a D.C. arc welder. d.c. current is imperative as well. Do some research, like at youtube, look for "hho generators" you'll find some cool videos. Some of them use dangerous catalysts though, so just be careful what you do with information you get on the internet. :)

[dknutson]

Or you could try a Dry Cell HHO generator. Supposedly better production.

[dciocoiu]

what is CU wire?

[Father Christmas]

"Cu" is the symbol for copper. In other words, "CU wire" is copper wire.

[imakethings]

no man i am praising you as you are my country man!

[sjs229]

ooooooooooooh!

[imakethings]

what is the gas evolved exactly ?

[sjs229]

sorry hydrogen and chlorine are produce not hydrogen and oxygen

[sjs229]

I think hydrogen and oxygen if I am not wrong

[sjs229]

Hydrogen at cathode and Oxygen at anode

[imakethings]

you are an indian right?

[sjs229]

Does it matter anyway?

[sjs229]

Please rate my instructable.It's my first one.

[collard41]

I think it would be better if you used pencil leads instead of Aluminium (im english) because the aluminium might react with the hydrogen given off.

[lemonie]

I agree. Graphite is more resistant to corrosion. However, if you electrolyse brine with graphite electrodes you tend to generate chlorine gas at the anode. Les

[collard41]

you do that with any electrodes. you'd have to collect a lot of chlorine gas to be harmful.

[lemonie]

No you won't, because chlorine will "eat" most electrodes. Also if you leave these things going you tend to find your electroyte mopping up chlorine and turning into bleach... L

[Kiteman]

I find that things like sodium hydrogen carbonate (baking powder) to be as successful as sodium chloride, but without the fumes.

[collard41]

Isn't baking powder Sodium Bicarbonate (NaCO₃)?
or something like that. Anyway, what is the aim of this experiment? to make Chlorine or hydrogen? or just for fu

[sjs229]

its NaHCO3
