[@amosbackstrom5366]

As someone who built MOT arc welders as a 15 year old, I completely agree. Although I'm not sure why you didn't use a proper welding machine to power this one..? Anyway, I wonder if you could develop a way to compress the oxide/charcoal mixture into a plug that acts as the electrode itself. You just connect the wires and the charge burns itself down. It would require some clever engineering to keep the current flowing, like it may have to be contained in a conductive sleave because the reaction would produce calcium carbide, which is not conductive. Honestly, it might be easier to use a separate thermite reaction to provide the heat instead of my idea😂

Use common pipe fittings to attach a pipe (scaffold pole) to the filling hole on the top. Use 2 bends to route the pipe along the side of the barrel about 9 inches away. Drill gas burner holes in the pipe. Place this on its side with the pipe at the bottom. Fill with wood and close the door. Light a fire under the kiln and wait fir the produced gas to catch fire. At that point you should able to let the fire go out and the process is maintained by the gas flames.

Charge with a mix of calcium phosphate, fine sand, a pinch of salt and charcoal in excess then arc it in a retort and you can make elemental phosphorus. A couple larger ceramic flowerpot works OK for the retort. Use some clay to seal it and bury it all in a sand pit. Use two thicker carbon rods and some steel wool to short out the rods and get the arc to start. A steel pipe is ok for the retort condenser. You can also use the CO created as a shielding gas. ❤

[@YodaWhat]

You can also skip the calcium and charcoal entirely, and just make the carbon arc underwater. The arc is much more than hot enough to work underwater. The carbon rods provide the carbon and water provides the hydrogen. Heat plus ultraviolet light from the arc splits the water. Controlling the arc length and arc current can significantly impact the production rates and purity of the acetylene. A slight downside is the acetylene comes bubbling out mixed with CO and H2, with a small amount of CO2 possible. The acetylene may be partially separated and concentrated by bubbling the mixed gases through acetone. Acetylene will dissolve more easily into acetone than will the other gases. It is preferable to form the arc in a chamber filled with flowing hydrogen gas, as that method avoids the production of CO and CO2, but requires the availability or production of hydrogen. Methane can be substituted for hydrogen in that reaction, which also produces hydrogen gas, H2. BTW, the reason for the soot cloud from the acetylene-filled balloons is likely to be this: Above 15 psi (1 atmosphere), acetylene subjected to a shockwave decomposes explosively into hydrogen and carbon. The carbon atoms then clump together into soot.

[@ralfvk.4571]

Nice idea, but how to get the rods under water and to collect the gas at the same time? It has to be collected very carefully, because of toxicity of the CO.

But he was mostly interested in collecting oil- and petrol-like substances and then occasionally processing them further into something that may be used as fuel. And the input to that apparatus was a lot of stuff, ranging from wood to plastic trash.

Im quite interested in 'scratch chemistry' being a guerilla chemist myself. The work that Wohler and Liebig did in the late 1800s, particularly with potassium salts, is s worthy of study for the chemist. Its rather amazing how many potassium derivatives you can make starting with potash from wood ashes if you have a moderately strong heat sources, i e. 200-600C range. This is a reaction that interests me, blending ammonium sulfate with charcoal and a small amount of zinc oxide or alumina catalyst and heating in a sealed, slightly pressurized SS cintainer to 350C to form thiourea. Thiourea can subsequently converted rather easily to both thiocyanate and guanidine base.

Next you can make some CS2 with it (If you don't know about this you can bubble acetylene through sulfur at 400°c but you must do it in an oxygen free system because of acetylenes auto ignition temperature. You will get little combustion followed by carbon coating inside your glassware but mostly just a low yield of Carbon Disulfide which you must condense to a cold vessel. It's undoubtedly a stinky prep, I actually love it. One of my favourite preps to do)

I can still remember the "safety lecture" we were given as postgraduate chemists at university. I put that in "quotation marks" because what it usually means is time for chemists to screw around and show everyone the most dangerous stuff on purpose. Several demonstrations involved filling balloons with fuel gases and then igniting them with a match on the end of a very long stick. Methane makes a nice whumping sound. Butane a deeper sound because it is slower. Hydrogen is much faster, almost a high frequency squeaking but very short-lived. Hydrogen mixed with oxygen is even faster and is quite loud - this mixture is called "detonating gas" for a damn good reason. They left the loudest bang until the end of the lecture - where they filled a large balloon (about the size of a beach ball) with a mixture of acetylene and oxygen. We knew they were serious about the sound, because they told everyone to cover their ears before igniting it - which they hadn't bothered with for any of the other demonstrations. But we were all grateful for that - the sound of the acetylene-oxygen detonation was the loudest explosion I have ever witnessed personally. I'm not sure how to describe it properly - but I will say that it was louder than the cannon on a WW2 tank firing right next to you. Also, the sound was not the only danger from it - several light bulbs in the lecture theatre shattered from it, raining broken glass down on us.

[@jacobe2995]

Make a vibrating funnel to place the ark weld into the outlet, then pore the dust into it and the ark welder should convert it as it falls past the ark. at least that's my thought on a possible way to make a better setup. Also it would be fun to see a video on how to make carbon nanotubes from acetylene soot. you could even use the soot from copper acetylide, Iron Acetylide Cobalt Acetylide or Nickel Acetylide because these metals are already used as catalyst in their production. I have always wanted to try this experiment but I don't have the time, tools or practical skills in this kind of thing.

[@Speeder84XL]

Awesome stuff! I did pretty much expected the bricks melting, mixing up with and contaminate the calcium carbide, to be an issue - because 2000°C is no joke, haha. Also, when looking at the temperature rating on fire bricks, it's often hard to find those rated for more than 1600-1800°C. Having an open arc and heat the powder directly a litle at a time is indeed easier. An arc also have the advantage of being able to dump a large amount of power on a small spot (which makes it possible to get up to very high temperatures without containing it)

The acetylene balloon could definitely use some oxygen to boost it's combustion. When it has that much soot is it running very rich. When it's at its correct ratio it burns with no soot at all.

Nice! Maybe you could try a follow up alternative using a few solar panels instead of the step down transformer...? They have the nice property of acting as a current source which can help keep the arc lit if discharge goes unstable [voltage automatically rises as current decreases] You can pull very long DC arcs from a series string - but here I was thinking several panels wired in parallel to give say 50V DC nominal at a few kW.
