I never would have thought to use a step up toroid to make an arc welder. That's brilliant! SOOOOOOooo much easier than rewining MOTs. Well. Time to build a better high current supply....
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😂
@@amosbackstrom5366my home built propane forge/furnace will get to a little over 2300F. I melt copper with it all the time and then add aluminum to make bronze, which I then used to make jewelry and decorations. If all you need is 2000 degrees, then I can easily get there with my propane furnace setup and a clay graphite crucible.
4:30 A video on a charcoal kiln, then charcoal gasifier (both of which have some Open Source Designs out there already) but ESPECIALLY Syngas to Methanol…to DME (and maybe dme to olefins or dme to omex etc) would be a GREAT series!
Agreed. Sure we have Propane bottles, but then we also have Acetylene bottles. It would be interesting to see what could be done to optimize the charcoal making process, by using its own gas.
Why is this guy not popular? Bro deserves it. This is what YT backyard science was all about. Compared to other "science" youtubers, this channel is actual science in action. I don't know how he did it, but he made everything engaging and interesting. I wonder what he can do with the level of funding and equipment the popular UA-camrs have access to.
yes this was popular in 1870- until post wwII. they were used in light houses for a long time too. Carbon arc lighting was important to the film industry and shipping industry for many years.
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. ❤
They used to use carbon rods in cinema lights, they have automated screws that keeps feeding rod to keep it lit. That's where the saying "lights camera action" comes from, because you had to strike the lamp every time you turn it on.
For anyone interested in wood gas, nighthawkinlight did a few videos on it, which were great. (I'm excited to see what our favorite Florida man brings to the table on the topic, as well, since NHIL tends to focus on very practical applications.)
I reckon you should do a whole vid about wood processing I find it personally very interesting as a Finnish person since most of our industry is just that. I do not know what it truly takes but you could try separating the different gases in wood gas.
" I do not know what it truly takes but you could try separating the different gases in wood gas." Destructive distillation of wood. Products can be separated using a fractional distillation column (same used for Crude Oil distillation) The heavier compounds condense at higher temps, & the light Compounds condense at lower temperatures. Mr Teslonian (YT) has a serious of videos on wood gasification. IRCC, he has a video of making fuel from Birch wood to run a small gasoline engine, as well as running the engine from woodgas.
I've watched videos of someone who made a pyrolisis apparatus in their backyard, it was a cool system, especially for a much younger me who enjoyed oil-processing-related stuff from minecraft mods and Factorio. His apparatus also used some of uncondensed gas to heat the chamber even more. 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.
your idea with the 110//220 V transformer as an alternative to ripping open a microwave is absolutely genius and will save me so much fucking around on a bunch of future projects. Thank you Pirate man!
-I ve done this and the best way I could make it work is on a large steel can and use lots of the calcium oxide and charcoal mixture so the same mixture is its own refractory container. I have made more than 100g of CaC2- NVM you came to the same solution.
i knew it was possible! this guy proves everything you thought you knew about chemistry but then thought was wrong because it never worked when you did it.
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.
You could make an Open Source Arc Furnace! (Also try and make diy electrodes from charcoal and tar which is then cooked?) Huge pile of work, but that tech being more accessible would be great!
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)
Incredible video. I am so glad that I got to see this reaction. I have wondered since I was a kid what the process looked like. It also inspired me as I have wanted to make an arc welder and never had the thought of using a voltage converter. Now I know what to use.
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)
It's not at all difficult to fond refractory capable of withstanding the heat. Simply buy lightweight fire bricks made out of zirconia instead of alumnia.
@@neon-john Ok, I didn't taught about that. If searching for just "insulating fire bricks", it's mostly the alumina ones that come up (like on Ebay or similar). Those are also what's available from most local suppliers where I live.
For anyone interested note that step-up/down transformer is *not* built to run at its rated capacity for any significant length of time. The power cord, plugs, the transformer itself, none of that is rated for 5kW continuous. To put in perspective I have a continuous 2kW German toroid transformer and it's twice as big with twice as big gauge wire on it and it's rated for half the power.
There is an arrangement of carbon rods for electric arc called Yablochkov Candle. Look it up on Wikipedia. Essentially two parallel electrodes separated with porcelain clay. It removes the need to continuously readjust the electrodes.
in the netherlands we have something called "carbid schieten" wich translates to shooting acetylene. It's a simple thing you can do during new years eve, you drink some beer and then you put a tiny amout of carbid inside a milk canister, then you put a football (soccer ball for ya american folk) and then you put a tiny flame on the backside and it goes off with a HUGE boom. all said, nice vid man. vriendelijke groeten (kind regards)
Builds makeshift arc welder to produce acetylene gas to "weld his boat back together", ignoring the arc welder he had to make in the process entirely. Perfect.
Really cool but i have to admit that as soon as you used the "marooned on an island" theme I was hoping to see you make everything with coconuts. That's REAL island science.
12:54 Not a partial detonation. I've done a quite number of experiments playing around with fuel/air/oxygen ballons around stoichiometry, and trust me, when you get close to detonation, you definitely know it. And so do your neighbors. Hydrogen gas is the easiest - I suspect you could detonate it with a lean mix of air. Propane needs at least 1:5 of pure oxygen.
YES !!! LOL glad you made a video on this, love the deep dive info coming to video format finally (now to get some info on triboelectric charging of nozzles from fuel flow of liquid fuel to increase the thrust per pound of fuel burned, and some extra protection on the nozzle to keep the heated expanded gas from contacting it on its way out into the air or space once it exits the atmosphere. (and how control over this and segmenting the delivery to the nozzle can use electrostatic power to steer the rocket via differing electrostatic charge pressure or ion pressure :)
It's a good thing you also found that arc furnace and power source on the beach. Couldn't you weld with that instead? 😂 In fact, those carbon rods can directly react with the calcium, skipping the driftwood part.
Reminds me of a paper (Julien C Marchal, et al, 2015) where they claim they could make solar grade silicon directly from rice hull ashes with an arc furnace.
Moissant, who pioneered the use of arcs to make this and other materials (including synthetic rubies). He used lime/CaO as well as carbon to make the crucibles and firebricks. He found out, just like you, that natural materials dont hold ip to the electric arc very well... Also, i think I read that some of the earliest carborundum construction at Niagra did exactly what you did: carbon electrodes embedded in giant vats of the mixed source materials.
Dear Mr Pirate, get Yourself a crucible for that arc stuff. I´ve seen someone make rubys that way. Marvellous entertainment always has sketchy, arcing ka blammos, that´s why I loved Mythbusters. Kind Regards
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. For cutting in the automotive shop, I generally run 25ish PSI Oxygen to about 5 PSI acetylene. I dont know how much that converts to by volume but it works great for cutting steel.
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. Possibly need series diodes to isolate each parallel panel from back feeding.
Growing up in the 70's, getting fist-size chunks of calcium carbonate wasn't too difficult... almost blew our kitchen sink off the wall when dropping bits of it into soapy water and lighting the resulting foam...
The flame speed of acetylene is significantly faster than propane which is why you see the acetylene flame burn faster. You can also buy calcium carbide ready to use with old school acetylene generators which are essentially like your flask setup at the end. They drip water into the chamber and feed the gas out to your acetylene torch. They're hard to come by these days (in first world countries) since everyone just uses insanely overpriced acetylene cylinders for welding/cutting purposes. If I were using acetylene on anything more than a hobby level, I'd probably look into getting an acetylene generator setup since calcium carbide is very cheap to acquire by the ton.
This sounds some factorio stuff "wow im stuck on this random island, its allright though ive got a burner mining drill and a iron, copper, stone and coal deposit to work with"
I read a chinese study that said its fine to use calcium carbonate directly. I haven't finely powdered my materials. I think i just keep ending up with a rock of igneous calcium because my arc is blowing away the little chunks of charcoal. I also didn't use firebrick, just an excess of material in open air. I was thinking i needed to pelletize the reactants together
I think I'd favour a large bottom electrode, like in an aluminium mill where the entire furnace lining is graphite composite. In other words just use a graphite crucible as one of the electrodes.
Very cool! I have no idea what I am talking about, but what if you compressed the powder into a solid puck then tried to run current through it? It might be easier to heat a solid puck, rather than a loose powder. Great video!
I never would have thought to use a step up toroid to make an arc welder. That's brilliant! SOOOOOOooo much easier than rewining MOTs. Well. Time to build a better high current supply....

Could make awhole series on electric arc syntheses!
When people ask me why I always carry an electric arc furnace with me I just direct them to this video
Mom: I got u the new xbox!
Me: STFU Hyperspace Pirate just uploaded!
if you're on a broken boat, it would just be better to use the boat battery to weld it together
I think I'd favour a large bottom electrode, like in an aluminium mill where the entire furnace lining is graphite composite. In other words just use a graphite crucible as one of the electrodes.
Real OGs know this is a king of random reference
Acetylene is extremely sooty when it burns with air. It will detonate when ignited with oxygen, and the soot goes away
I havent even left school yet and i got the new hyperspace pirate vid
Glad I saw this before it gets removed for being "unsafe".
1:35 - You shot yourself in the foot. If you already have an electric arc, you already have a welder, no gas needed.
Very cool! I have no idea what I am talking about, but what if you compressed the powder into a solid puck then tried to run current through it? It might be easier to heat a solid puck, rather than a loose powder. Great video!
