A few years ago I started working with silver and gold. After that I decided to start making jewelry. I then needed a torch so I bought an Oxy/Acetylene torch. With that comes tanks, regulators and the hazard of storing explosive gases. Not liking the idea of that I started searching for an alternative.
I found that it is rather simple and inexpensive to make a gas mixture called oxyhydrogen. Oxyhydrogen is a mixture of hydrogen (H2) and oxygen (O2) gases, it is typically a 2:1 molar ratio. It is the very same proportions as water. The gas has been termed “HHO” or “Hydroxy Gas” by green companies.
The gas is produced from the electrolysis of water. There are two types of electrolyzers that can be used to create this gas. One is a wet cell and the other is a dry cell. I opted for the dry cell as it’s design is far more efficient. One of the things that makes it more efficient is that there is no current loss from the edges of the plates being submerged in electrolyte as is with the wet cell system.
I used stainless steel plates in hopes that they will last a good and long time before needing to be replaced as stainless steel is sort of expensive right now. Nickel also works rather well but is also rather costly. I have heard that you should scarify the surface of the plates but I did not and everything seems to work well so far. I actually think scratching the surface of the plates would cause them to become worn quicker.
Now that the electrolyzer is assembled I anchored it into a wooden box that I built out of scrap wood to make transporting and storage much easier. The beauty of this system is that I do not have to worry about storing or transporting dangerous gases although caution still must be observed and on some levels even more so than typical industrial gases.
This here is the secondary bubbler/flashback arrestor. It is used as a safety precaution to stop flashbacks from damaging the primary bubbler and also to help clean the gas that we create.
This is the fully assembled Oxyhydrogen generator in a simple half box. I will probably add locking casters to the bottom on the back and then a handle on the top back to allow me to pull it around.
This video is my HHO generator in a box to make it more portable. Sorry the video is sideways, the orientation sensor in my camera is off for some reason or I may have been holding the camera sideways. I am unsure, was to psyched that it is working to pay much attention to how I was filming it.
This shows the hydroxy gas being created. I ran a test to find out what the LPM “Liters Per Minute” is before I try this with my torch as the torch needs to have about 1 LPM to create enough back pressure so there is no flashback and possible explosion.
I found that with the 12v 19 Amp power supply that it only outputs 1 liter every 1 1/2 minutes. I had anticipated this and am happy with these results. Now I can use a decent power supply that is 12v 45 Amp. This should create more than enough gas to suffice.
Shortly after this I had a 1 liter bottle full of gas and nothing to do with it. I decided to put it on a stick in the ground and take a 5 foot long stick with toilet paper on the end as an ignition device and launch the bottle like a rocket.
Let me tell you what. That was loud as heck. The bottle launched over 100 feet or more into the air. After looking at the rocks under the base of the stick I used to launch it from I noticed a nice little crater about 1 foot in diameter.
Bottom line is experimenting can be a lot of fun and even beneficial but this is serious. You should not play with this type of thing if you do not know what you are doing. I cannot stress that enough. Please be safe when experimenting.
