Pressure Pot Cornish Generator

[candyman55]

I have been making Hydrogen with this for the past few days. so I wanted to show a pic or 2, cause it is so simple. And I think that if you are careful it can also be done safely.

This is the paint pot I use, I started with an aluminum one but the steel ones are galvanized and you can do the reaction right in the pot. When I used th Aluminum I put the stuff inside a glass jar but it kept foaming over and as soon as the water bubbled out the reaction stopped.



This is a pic of the vaccume pump I bought off ebay for less than $100.00 and it has been worth every penny.



The pot uses only Water, Aluminum and Potassium Hydroxide. And produces pure Hydrogen with no electricity. I usually put in about 4 to 5 oz. of Aluminum chunks or what ever I can find. About 1/2 gallon of water, tap water is ok. And 1 scoop of KOH - 1/2 lb. Crank the lid down and keep an eye on it, it will start to produce quickly.

I am not sure exactly how much volume this combo will produce but I can easily fill an eighteen # propane tank to 160#'s and then I vent off the rest. I am sure I can fill 3 or 4 with one batch. The tank gets quite hot in the process and when you vent the excess pressure do it outside.

WOOT !
thank you for that information !
...
Now have you got the camp stove to work on the hydrogen yet ?
I am wondering if I am right in my guess about the jet size !

This sounds very interesting

Where do you connect the vacuum pump to the propane tank ? if so exactly what is the process ?

I am having Brain wondering problems again with a simple method to introduce this gas directly to a car I found a PDF a few days back that explains in some detail how to do this but my brain keeps thinks ... I have a direct Injection Engine which is supposed to mean ( I think ) that the cyclinder is already filled with air before the fuel is introduced and the computer works this out for you, Why not just have a presure reduction valve thats ajustable and feed H2 direct to the existing injectors the computer opens the injectors at the right time and for the correct durations that is required for the fuel in the line which may be around 20 odd PSI (not sure) so having H2 in this line at the correct presure should work but proberly wont

NEED INPUT NEED INPUT NEED INPUT - some one here must be able to set me right while I crawl into a double roomed bomb shelter so I dont blow anything up including me LOL

[Bob]

I gave that idea lots of thought Kiwi and I think useing Hydroxy gas that way might work
but Hydrogen ...I dunno it has less bang for the buck than Hydroxy gas and you might find the engine running realy lean on Hydrogen alone...
...but remember if you take the Liquid gasoline out of the injectors and put a Gas ( not liquid) in them you are going to get less out of the injectors at a given Squirt because
gas is larger in size.... but then it flows much easier too so it might work just fine ...
I dunno... its certainly worth a try....
I was thinking of making a Hydroxy gen and fill a small pressure tank (complete with a pop off cap) to pressure up to about 35 or 40lbs pressure... and have the hydroxy generator turned on and off by a pressure switch... so it would cycle on and off as you drive.
...
to me this is probly the easiest way to go 100% hydroxy gas in the car.... IF it works
but we won't know till someone tries it !
...you will still need a very large generator to keep up with the demand the engine uses
but we already know that....
so if plugging into the injector bank is the answer it is a real simple fix !
...
I plan to try it one of these days ...probly next summer !

Ok, I hooked up a propane space heater element to the Hydrogen gas from tne generator and this is what it looks like, I didn't use a regulator and I only did 10#'s of pressure cause the vinyl line kept blowing apart.



I ran it for about 45 minutes, The hydrogen trys to ignite every where it can get air. So I had to cover the air holes in the burners completely or it would burn in the tube. With more pressure this thing will heat up a lot more. But it looks like the burners are going to have to be reconfigured a little.

[Bob]

Hummmm makes me wonder...
guess I'll have to find me a paint pot....
I found an old pressure cooker that would work.... but its alumimum...
so I can't use that ....
...
I have a attach to the bottle type of heater unit that works great... I have 3 of them I think around here ... their on -off valves are pressure regulators in themselves...
but I am wondering about what you said... that the hydrogen wants to burn every where it can find air....  I think ...that might be because of the low pressure... but I'm not going to bet on it....
...
I wish I had a pot I could use for that stuff... My metal pipeing realy isn't thick enough to make a real good one...
I'm still looking for alternatives to make a cornish generator!

If the valves are pressure regulators then mine probably is to, maybe that is why the hoses kept blowing. (too much back pressure)   I am going to try one (a pressure regulator) like I have on the pressure pot and maybe drill out the orfice.
I tried a gas grill burner, the single one that u use like a stove burner and the flame kept burning in the tube and never lighted the burner. That is why I taped off the air holes on the heater burners and then the burner lighted instead of the tube. 

There justin i worked on it make sense now? sometimes I think in abstract

yaull got me lost.   haha

well I think I am going to try hydroxy with my idea I thought about it as well long ago until I was told it didn,t mix well with air but that is in the past It may just work fine no gasoline just hydroxy injected car comp is fooled opens injector timing longer due to o2 sensor for more fuel but stops critical limits ( just how much PSI and LPM that is who knows ) but let the ECU decide

I have pulled my original cell apart and rebuilding it was 4x 7 serries plates giving 6 cells x 4 in parallel same bath would draw about 30 Amps with 1.5 LPMapprox me thinks each cell under powered so each cell needs tuning for 2LPM from 20AMP seperate bath/elocorite for each then combine in parallel me needs a bigger alternator

[Bob]

Candyman... I take it your saying you tried a normal camp stove and it burned on the orface not on the burner itself.... and thats why you taped up the air inlets on the heater burners... Ok now I'm beginning to understant... in other words ...
Hydrogen is not like Propane in that it wants to burn much easier... it wants to burn on the orface or jet, instead on the burner...
This might be a problem... when trying to run the entire house on it
say the furnace , cook stove and water heater...
the water heater can be adjusted real easy as there is a real good adjustment on most water heaters that will close off all the air and force the gas to burn out of the burner, instead of the orface...( at least I think so anyway!)
but the cookstove/oven is another can of worms that may or may not be able to be ran on Hydrogen......
as far as I know, I think the burners on the cook top can be made to work fine as long as a person does some modifications on the fuel/air mix on the burner adjustments...
but... I am afraid that normal adjustments ( like close off the little door and leave it at that) simply won't be enough... but I think that will depend greatly on the Hydrogen pressure... as will the pilot light...which is usually adjusted on the stoves control box/regulator...thingie...
...
same goes for the OVen... it will have to be adjusted to shut off the air completely on the burner... and the pilot adjusted...but then it should be self regulateing like normal.
...
this shutting off the air might  or might not be real simple... depending on the Pesky
Hydrogen... sense it ignites super easy it will want to set on the orface and burn
but what normially keeps propane off the orface is the pressure... I think and it forces the flame out to the burner holes on the burner
... IF more pressure  cures this problem its a simple fix, just increase the jet hole size
...
However I remember Playing with a throw away camp stove I found years ago  trying to see if I could get it to work , it was a propane camp stove  and the jet was missing.. I found a bolt screwed it in the hole and then drilled a small hole through it to act as a Jet....
I had exactly the same problem Candyman is reporting  the flame stayed on the orface/jet
and wouldn't jump to the burner top where it should be....
I then drilled the hole in the jet out 2 drill sizes bigger... and tried it... and it sprang to life with flames about 2ft above the burner...but it wasn't burning on the jet any more eather!...  I still have that camp stove and I use it if I want allot of heat fast !  because that thing will boil a 1gal pan of water in less than 10 minutes ! <GRIN>
...
thats why I think opening the jet a SMALL amount will help the hydogen burn on the burner and not the jet!
 what happens is where the jet is is too rich for the gas to burn so the flame front moves to the top of the burner where it should be... but that works fine for propane , I don't know it that will work with Hydrogen... it may set on the jet and never move no matter how much pressure is applied... if thats the case then as Candyman said all air needs to be removed completely for it to burn properly ...
...
 I'm guessing too here... I've never tried useing Hydrogen on anything... but I realy
like the idea of makeing my own hydrogen and useing it to power things around the shop...
like a heater and a forge... and maybe even the cutting torch.
 I figure if I can get it to work acceptably there I'll move it to the house !
....
Auto-ignition with a pilot light is a must though for the oven and the furnace...
the cook top can be hand lit with no problem...
so the pilot light system has to work flawlessly before I will use it on a furnace.
...and I think its just a matter of adjustment !...but I could be wrong!
....
 I made a forge to melt alumimum a few years back... powered it with Kerosean and a fan
and it took a good 30 minutes to get the alum to melt...
I switched to propane and it took barely 10minutes to melt the same amount of alum.
but it realy uses the propane fast ! Useing Hydrogen would be much better...and safer than propane in almost every case simply because Propane is heavier than air and will sink
where Hydrogen is lighter than air and will rise... this is the same reason many people use natural gas instead of propane... incase a leak or a pilot light goes out the gas will rise and disperse instead of filling up the basement and waiting for a spark !
... Bottled Natural gas has been used on boats for decades now because its far safer than propane to cook with.... I think we will find Hydrogen has much the same qualities.
...
my 2 coppers worth! <grin>

Bob the burner I tried was the side burner off of a gas grill but you are right the gas burned on the orfice. Yes I think that it takes a lot less o2 for hydrogen to burn. I have been looking ath the burner on a coleman stove if I can figure out how to inject the gas without routing it across the burner like it is designed.

I checked out the heater today that I used for the tests and the regulator is built into the control. that is why I couldn't get it it work very well, I believe we need an adjustable regulator and possibly a little bigger orfice.

I don't see why the pilot light won't work well with hydrogen. The space heater had a thermocouple on it and every time the flame shut off for what ever reason it worked fine.

I am going to refill the Propane tank with gas from the  generator I want to see how many liters of H2 there are per # of pressure in an 18# tank. I also would like to know if anyone has any Idea what the % of O2 to H2 there would be in Hydroxy.

[wess]

About the % or ratio of hydrogen & oxygen is H2   O1  Thus H2O. That means its 2 molecules of hydrogen & 1 molecule of oxygen. Water is H2O. Electrolysis breaks the molecules apart. Just in case you didn't know. This hydrogen use is really shaping up thanks to Bob & Candyman. Glad I started people thinking what with winter coming & a depression to boot, we'll need something homemade for sure. Good ole Yankee Ingenuity..nothing like it..thanks to everyone. P.S. I believe that most stoves have a air adjustment slide on the pipe before it goes to the burner. I think you can slide it & actually shut all air off to the burner. I dont have a gas stove now but I had a propane stove & oven and remember adjusting the air to it. Bob, a plastic coffee container might work inside a aluminum pressure cooker. It would be high enough to keep water from boiling over into the pot. ??Maybe...lol..
   I'm really excited by all this & hope to experiment this weekend if I have time...

[Bob]

So How goes it guys ? has anyone got a Stove to burn properly yet ?
Or found a Paint Pressure pot at a flea market ?  ( I been Lookin'!)
...
My experimenting days are almost over for the next 4 months as when the snow hits its too cold to go outside and do anything.. Had frost bite too many times and I hate the cold now ! HAHAHAH..
I guess I'll have to move the drill press inside the house ! HAHAHAH... HAY YAH ! what a good idea!
... (I'm all healed up from the last time I did something like that and the wife took the fire place poker to me , so what have I got to loose ? I'll just be sure to hide the poker this time.. and the bat !)   HAHAHAHAHA
...
..
.
But anyway, I've been thinking that filling a Propane tank with Hydrogen will not be completely FREE
... as Candyman pointed out a scoop (Probly 2lbs!) of KOH  ain't cheep ! and the aluminum most of us can scrounge up... but a 40lb bag of KOH should cost about $50 bucks or so but give you enough Hydrogen for a year at least !
...
I was contemplating using a refrigerator compressor as a vacuum pump to suck a vacuum on my propane tanks....
 I dunno if that will work, but sounds like it should !
and I have junk refrigerators around here ! <GRIN>  it may take 8 hrs to get to a vacuum but so what !
hehehehehhehe
...
..
.
so I'll just move the Hydroxy cell making into the other room ! thats the ticket !
...
I can just see the wife's reaction when she comes home in the morning to see the liveing room full of drill press, Milling machine, shopsmith, grinder,welder and tools... should be something to see.... from a distance anyway !  HAHAHAHAHAH

Bob,
I haven't worked on much since deer season came in. I took all of this week off to help smuff out my share of the little boogers. So far things have been going great and I think that I got em on the run.

The scoop that I use is 1/2 pound and the less water that you use the quicker the reaction starts. It seems that the reaction uses up the KOH cause when it is over sometimes there is still aluminum left in the container along with water. The water left over is hignly conductive according to my ohm meter.

I don't know how much H2 that I made with 1/2 lb. of KOH and 4 oz of aluminum but it filled my tank to 160#'s and I vented more than I was able to save. I talked to the guy at he propane filling station and he said that the tanks are rated for about 300#'s but he said he would be hesitant to fill the tanks much above 150#'s.

I think the next thing is to find how many liters of H2 will fit in a tank. We really need to find out how much hydrogen is in a liter of HHO. My guess is that a liter of H2 has more than 2 times the amount of hydrogen than a liter of HHO. By varying the percentage of O2 to H2 we may be able to control the rate of burn and temperature of the burn. If the rate can be slowed perhaps the timing adjustment will not be necessary.

OK enough rambling for now, its supposed to warm a little today need to skin some of these deer.
