Hey /diy/, I want to build a HHO generator to power a small torch, the only problem I have is how to place the steel plates to optimize the gas production, the factors I'm worried about are the separation between plates and the total area.

If someone is worried about it exploding I've filled a small container with steel wool that will be attached to a bubbler to prevent explosions.

This are the initial schematics for the plates disposition, there is 5mm between plates, but I think I should separate the 3 or even 2 mm, , the maximum height the plates can have is about 7 cm, I've thought of making them of 5 cm so there is more energy passing through the water, I don't want to have too much area because I'm afraid I't will let pass lots of energy and I won't get enough HHO.

How many square meters should I use to be powered with a 12 car battery?

The steel wool divides the HHO into small parts so if the flame gets into the tube the explosion won't be able to pass through it, also id it fails theres a bubbler with a pipe going into the watter so small bubbles have to reach the surface, isolating them so the explosion can't reach the cristal can.

I think it is a spark arrestor. You use the same sort of device oxygen using torches like oxy-acetylene. The OP's setup will be oxy-hydrogen.

>>474091
I've been wanting to make an oxy-hydrogen torch since forever, but haven't been able to locally find the sheet metal I want to use.

There are many square plate designs online that use some sort of gasket system between the plates to contain the water and isolate the plates. They are "dry cell" designs like in this image.

Neat, so it's a homemade flashback arrestor that's built like a spark arrestor on a engine exhaust.

The flashback arrestor on my torch makes a clicking noise when you turn the torch off so I assume it's actually some sort of valve or something.

You'll get around half liters of oxyhydrogen gas per 1Ah of electricity. Thus, one liter per minute flow would need a 120A supply. If you use 12V supply, most of the voltage will be wasted, unless you have several electrolysis cells in series.

>The flashback arrestor on my torch makes a clicking noise when you turn the torch off so I assume it's actually some sort of valve or something

It most likely is a type of check valve. The same thing can be installed additionally to a homemade oxyhydrogen torch for added safety.

The link you provided uses a "wet cell" design. "dry cell" designs are more efficient, but a little more difficult to build.

>> No.474180

>>474134
Yeah, you need a low voltage, "high" amp power source. The cells need to be around ...2.5v I think, I don't remember the optimal voltage off the top of my head (look it up, sorry). People stack them in series because most people don't use a 2.5v power supply. However, if you did have a power supply that met the single cell voltage then that would be far more efficient than anything else (and a 12v PSU would of course be wasted as you say). You'd then just hook up more cells in parallel if you need more fuel to be made with the 2.5v PSU.

Seems like a "power factor corrector" (PFC), which isn't really needed in most homes in the first place since most devices with this problem have power factor correcting circuitry in them already (like a PSU on a PC). Only big ass motors need that stuff and randomly plugging in a bunch of capacitors isn't really a good idea. Most new house air conditioner units use DC motors and a switching PSU with a boost converter to do PFC already.

Which is why in the video I'm posting they are using an AC motor that doesn't have it's own PFC. lol

Thus, the device works, but only if your house appliances don't already perform that function.

You need to match the voltage with how many cells you'll have to get optimal power usage versus oxyhydrogen output. It should be in the 1.25-2.5 volts per cell range. So, divide your input voltage by the number of cells to find out how much voltage you'll have per cell.

>>474463
>two 1000 microfarad resistors

Oh, do tell, you sound like an expert on the matter.

>dripping sarcasm, pic related

That device does work, but it isn't a massive energy saver because modern most appliances already compensate for power factor and it will only work on circuits that are connected one buss on your breaker/fuse box.

Inside it has capacitors/inductors that help compensate for power factor from unregulated devices. This reduces electric use.

But, like I said previously, this device is bollocks in the 21st century. It'd be great for the 1980s when next to nothing you use in your home corrected for power factor. It isn't a snake oil device, it is just a nearly useless device today.

Thanks for the explanation, I was going to use about 6 or 7 cells but I don't know if I should put the plates by pairs or I should leave the same distance between them alternating the polarity like this (+ -+-+-+-+-+....-)

>> No.477942

So let me get this right:

You want to put O2 and H2 through the same tube and light it up on the way out? That's a very elaborate suicide device. Why don't you extract H2 to one tube and O2 to another, and mix them where you want the torch to be, this way there will be no way of the fire going into the tube. That's how the welding equipment works too.

>> No.477952

>>477942
Making the H2 and the 0 go through different tubes may seem easy but it isn't, it's easier to make both gases flow through the same tube and create different security systems to prevent explosions even if the fire gets into the tube.

The bubbler will isolate the gas from the fire, in case it fails (even though they are relatively safe) a pot filled with steel wool will stop the fire to get into the generator creating a bigger explosion.

I will also add pressure valves, one to the bubbler and another one to the generator, to let the pressure flow out before it blows up the containers.

may seem simple but it isn't? Resdesign your plate so the anode and cathode are separated into different gas chambers

How I would be able to sepparate the anodes from the cathodes and create different gas chambers when the disposition is (- + - + - + - + - ++ - + - + - + - + -) and the maximum gap I can let between a positive and a negative plate (a cell) is 2mm?

It would be way easier If I had 1 anode and 1 cathode, but I have 10 anodes and 10 cathodes.

Try pic related with 20 cells, but without increasing the power supply, It's impossible.
