I made one of those 4" x 8" PVC hydrogen generators. I had ran it but forgot to purge it. The ? nipple on top was open and a spark from the grinder flew past it? HOLY BOOM, good thing I didn?t glue the joints.

Hi hartiberlin and the rest-

 I like the idea of adding some air, reminds me of that New Zealand guy(forget his name just now) from years ago who came up with a similar system where he bubbled air through a series of electrolysers.
 However... some guys who have done extensive experimenting running hydroxy through small 4 stroke ICEs say that the hydroxy gas is at a perfect burn ratio already at 2:1. They go on to say that in fact that they had to completely close off any additional air intake or else the engine wouldn not run at all !
 So what do you think? Is there a difference if it's first bubbled through the electrolyser in comparison to the normal additonal air intake at the carborator? of course the air would now include some water vapor but wonder what other features it might have?
 Then once the engine is running you could recycle the exhaust back through the bubbler again to recapture the water if you wanted too and then you wouldn't need an air pump at all would you? after all the exhaust would be very clean

PS - good work Walter - look forward to hearing more. Now we need the amps/gas volumes if you could-thanks!

Hi all
thats what I dont really understand how only the change from vertical to horizontal can change the whole water. It was allways my probleme that with the vertical version the water turned brown or black greenish what messed up the cell after a while.Some one has a Idea?
greetings
walt

Hmm, why the water does not turn brown with the horizontal
version I also don?t understand.
Walter is all the water in both cells seawater with some KOH added ?
Or was it destilled water ?

Maybe you can still install a sucking pump on the gas output, so
you always have a lower pressure inside the electrolyzer box.
This will probably double or tripple your gas output at the same
input power level !
Also mix the gas output with enough air behind the bubler or inside
the bubbler with an aquarium pump, that also goes into the bubbler,
then you don?t have so much explosive gas, but it will
burn also better in the IC engine, cause it is there again
compressed in the cylinders.
Also via the mixing with enough air you will get much more
gas all in all. This should then be enough to run your engine.

Hi stefan and all,
thats the crazy thing on this, the water is from my well but it does not matter what kind I use it is allways the same result, in this case for demonstration i used my regular tap water from my house. I used 1/2 gallon and added a 1/4 teaspoon of KOH ( 93% pure) mixed it till the KOH was dissolved and pured in both chambers from the sam mixture. the contactivity was 2400 TDS what gives 3.73 mS/cm.
I did a short test with a 500ml plastic bottle like you have recommended stefan and it took 70 sec till the water from the bottle was out, what means the cell generates about 1/2 liter every 1 minute, the pressure on the bubbler was 0,75 psi on the gauge. I dont know right now how much I need to run the generator engine 5 and 12 horse power.
I will try the aquarium pump version and see if this works.
The picture shows the cells 16 hr after shut down and there can be seen on the left side where the vertical cells are the thick brown resedue on the bottom and the brownish water, where on the left side there is pretty much nothing.
I will try to post another short video from a comparisson of both plates in horizontal.
greetings
walt

I see, it is funny, that you are still smoking , when doing these experiments !
Better watchout and don?t get too near the ballon with your cigarette !
Booom !

Hi stefan,
nice comment, thanks 
walt

Hmm,
Walter, what is the difference now ?
Both cells now have the main plates in horizontal... ?

I love watching the video ...but the cigarette scared the hell out of me.

Have a look at this one

if my calculations are right this Stanley Myer reproduction is producing the gas (do not know volume so am building one my self) using only 24 watts.
Kind Regards

Hi mark,
dont worry the cigarett is only there as long as everythings in the system is closed believe me.
like I posted yesterday, I did the volume test yesterday and the one cell what is still a vertical version puts out about 1/2 liter in 1 minute. I will try to put now the horizontal disc in a filter housing and do the same volume test.
If all this works then I will try on the weekend to fire up a small (3hp) engine to see if it is running and how it performs.
greetings
walt

Hi Walter-

 Thanks for posting the video. Hey, maybe you discovered a way of cleaning up filthy water 
It's interesting that the water should react different in the different setups - that deserves further investigation for sure.

 Regarding gas production differences, spacing between electrodes is of course very important and I couldn't tell if your spacing of the plates was the same or not between the two setups?

 Keep in mind that using any more than 2 volts doesn't provide any gain in gas production. For electrolysis you need a little less than 1.5 volts to start the process and gas production will increase on up to about 2 volts. After 2 volts you don't gain any in gas production and in fact you will waste a lot of energy and produce heat etc. So in your setup of say 12 volts and 12 amps you have a 144 watt unit (watt = amps x volts). You could have a 2 volt unit @ the same 12 amps and have a 24 watt unit producing the same amount of gas. Using the same amount of power you are now using (about 144 watts) you could run 6 - 2volt units and produce 6 times the amount of fuel than you are now, with the same 144 watts.

 1/2 litre of gas/min isn't enough to run your small ICE likely but it would be a nice supplemental fuel to try out for sure and see how the engine reacts to it. You can calculate the fuel required if you know the cc of the engine.

 Great fun though this experiment of yours. Its very important to show the value of different electrode design configurations and its effects on electrolysis. Keep us posted!

Best Regards,
