separating H2O by hydraulisis

[love2fish93]

Has anyone made a setup effecient enough to produce any usuable amount of hydrogyn? I need a theoretical and possibly testable setup for an "over the summer" project

thanks,

Pat

When I was a kid, I took one lage syringe body (https://www.hstt.net/webshop/images/SPRL60.JPG).
I put a wire in it, and fixed it in a jar of water. I sucked the air out at the top using fuel line from my gas planes.
Put another wire somewhere else in the jar, and apply DC voltage around 12V.
The negative electrode produces H2, as I recall.
You can add some drops of sulfuric acid to increase conductivity.

thanks for the help, I think I have a good design to successfully do that.

Something like 8th grade... we used the gasses resulting from hydrolysis to:

Fill one balloon which was popped by the teacher by igniting it...quite a bang.
Fill several glass jars and burn steel wool.

Steel wool will burn passably without the high O2 content... but with the extra O2 its impressive.

Salt acts as a GREAT conductivity agent in water, and is easy to get!

It increases the efficiency by several fold...

the only problem is that the NaCl will be broken into sodium hydroxide + chlorine gas which will bubble around the anode and the sodium hydroxide will attach to the anode. The hydrogen will not change and bubble to the top of the cathode.

There is no oxygen given in this process....it stays in solution.


Remember chlorine gas is very toxic and in high enough concentrations it can kill you.

I remember using a dc train transformer, a jar with some "washing soda" added to water, and two carbon rods (from zinc carbon battery-the ones before alkalines came along). The two wires from power supply were wrapped around separate carbon rods and placed in solution filled test tubes. Each test tube was inverted and the gas formed displaced the liquid. Voila- O2 in one and H2 in the other.

I've heard a bit of baking soda in the water works well to improve the output. At least thats what all the "run your car on water" sites say. (theyre pretty optimistic snake oil salesmen)

may help. Be careful...the reverse reaction is called 'Knallgas Reaktion' for a good reason. We measured well in excess of 90dB when igniting a very small volume of the right mix of hydrogen and oxygen. Stay away from using salt (sodium chloride) for the reasons mentioned.

Anyone try sparking water like you would gasoline in a car? You can and if done correctly the output is 14x that of gasoline...yep, you see correctly 14X that of what you now put in your tank.

Yes, water can explode. It takes the correct spark. Proper temp, dwell, frequency (which is ramped in amplitude).


I'll see if I can find some old notes on this...we did this several years ago and were able to punch a hole in (1/8" if I remember correctly) aluminum plate...no projectile, just secured it over the bore of the "cannon"
