A prism or two inside a telescope-like apparatus is pretty simple too if you only need a spectroscope’s qualitative measurements. You can buy them from AliExpress for $3 or something with two plastic prisms and a mirror between. Relying on differential refraction as opposed to diffraction means you don’t get nearly the precision you would from a diffraction grating, but it’s more than good enough for a simple spectroscope. An actual quantitative spectrometer would make for a really interesting project, and personally instead of using a CCD or photodiode I’d use something like an RE200B on a swinging arm, that way I could measure down to wavelengths far longer than 1μm. So long as I swap out the diffraction gratings, that is.
The process you’ve demonstrated here is the same reaction that occurs on an industrial scale to make CO and H2 from coal and water. Look up process called steam reformation. This process also works using natural gas instead of coal. You may want to try the process in a future video using some natural gas and water together and then applying the high heat from the arc. Would be interesting to see the results.

This isn't that different from a wood/coal gasifier. Used to run busses off coal gas during the war, back when all the proper fuel was needed for tanks and spitfires.
Make your wood gasifier as efficient as possible, make a couple different types of condensers, filters and purifiers to see how clean you can get the end product. It would be really cool to test different batches using different types of woods, setups and see if the burn or color change.

It would work for getting pure water, because after you burn the gasses, you can condense the water vapor and collect the water. You could also trap and compress the CO2 and end up with pretty pure CO2.

It is not a 100% energy storage method, since the carbon electrodes are consumed, and they turn into CO2 when the CO is burned. So you are still burning carbon, only in two steps.
@@Derived_One Potential energy - pump type hydroelectric plants, which work like any other hydroelectric plant (dam, difference of levels, water goes down from above, passes through a turbine, boom). They have, however a possibility to pump water upwards when there is lower demand for electricity in the grid and releasing them when the demand is higher. They play a great role in stabilising the power grid actually. Big downside - size, cost and need for water reservoir - not too many places you can build that, and if you can, the local environmental impact is very high. The efficiency comes from the fact, that there is not much energy loss when pumping a liquid - and large machines are generally more efficient than small ones, so overall efficiency goes quite high.| Fun fact - in such plants the turbine can work as pump and a generator as motor. No need for separate pump units. Hope I have interested you a bit in the topic (of course if you did not know this already :D )
@@Derived_One when enough electric cars are on the grid that will be a pretty efficient short term store. Long term storage would really be chemical or potential.
This guy is awesome. Love your videos. I have always been a nerd that loves science and I often isolate myself from others just to do these things. I'm obsessed with these experiments. Keep up the good work.
Absolutely incredible! I had no idea that the heat of an arc could be used in this way! I was wondering about striking an arc underwater though, and glad I didn't, I had no idea CO gas would be generated.
For the separation of products you may use water shift reaction. Not a separation per se, but will yield one product, and IMO the more interesting one. And it will be great to see WSR in a workshop scale.
I know that the main products are monoxide and hydrogen, but the super high temperatures of electrical arcs are strange things and can produce unexpected complexity. I would like to see the product gas run through a mass spec to see what trace species were also produced. I bet you would see some methane, ethylene, acetylene, maybe even ethane in there. Recall that a simple spark in an atmosphere of hydrogen, water and ammonia produces a rich array of amino acids (Urey-Miller). I don't think anything as complex as that is being created in a setup like this (no time for it), but all the same, I bet there are interesting complex trace components in that gas, perhaps even exotic things like endohedral fullerenes.
The proportion of acetylene might be significant, considering that passing hydrogen inside a carbon rod electric arc is how acetylene was first synthesized.
I have a Masters degree in Electrical Engineering and I keep learning new great ideas from your videos.. Thanks for your effort to make this experiment.
As far as I remember from my chemistry classes, Carbon Electrode breaks down to generate highly reactive carbon atoms under high temperatures which has the ability to combine oxy-hydrogen atoms to generate an into an hexagonal intermediate unstable molecular state, and finally, another nascent oxygen or hydrogen splices the intermediate species to generate methane, acetylene, ethylene, methanol, formaldehyde or formic acid, which can react back on the intermediate stage to generate a multiple combinations of hydrocarbons, aldehydes and ketones. So I believe its not a single species of gas produced, but a mixture of all probable organic molecules depending on the exposure time
Mate have just recently stumbled across the wood gas concept and seen your videos about it and had to subscribe, definitely glad I did now!! You're a true "mad scientist" 😄, I love it!!
Bearcat Ben Mine too, but when you think about it, Methane burns in Oxygen, so the carbon Atom would rater have the Oxygen bound to it than the Hydrogen.
He made Syngas. I'd be slightly surprised if there isn't some hydrocarbon contamination in his gas. If he got the arc going in it, it may randomly produce hydrocarbons. Add some nitrogen, sulfur, a pinch of phosphorus and maybe a couple of other ingredients, and the arc would make some of the building blocks of life, like amino and nucleic acids, proteins, maybe lipids and misc. UVC light might be a better way though, a little gentler so it might not rip stuff apart as quickly as it is stuck together. Something like that is thought to be why some asteroids have some of that essential to life gunk. Such gunk, plus time, might be where life started on Earth.
8:12 I love how he goes full [calculation mode] right there and you just simply know that those numbers are running in his head so freaking fast that very second and as a nerd I love watching it
I'd love to see you tackle making your own Vanadium redox flow battery. I've always thought they might be a great candidate for grid level storage as their scalability seems pretty good.
I tried it 15 years ago! The idea was to scrap the particulate filter of a Diesel engine to make the carbon rods and use its generator when decelerating to create that synth.gas, which is then burnt while accelerating. You can't keep the gas mixed for a long time, H2 is so much lighter than CO....
It's more likely that the sodium was simply present in the leaf strewn rainwater to begin with. Sodium is an incredibly efficient converter of various energy forms into yellow light (the d-lines), there's a reason it's been used in every street lamp in the world for the past half century up until very recently.
not really the glas because carbon rods for making light are doped with salt to change the lightcolour from something blue ish to warm white and this rods he use are clearly for arc lamps seen them before several times
@@incrediblemichael You don't know what you are talking about lol. Those are carbon arc rods for removing metal such as welds that need to be redone, or back gouging for weld prep. Those are not rods for acr lamps. I am a welder with 30 years of experience, and I have used those exact rods many many times.
Really interesting point about the yellow flame indicating sodium contamination. If you haven't already (I haven't looked), that might be a cool topic to explore: what different flame colors tell us about the elements being oxidized. Anyway thank you for the excellent video
I have a 19KW solar system that I am going to go off grid with. The climate I will be in is not suitable for batteries. Thank you for this video as I can now use my array to power the homestead during the day as well as make gas for storage to keep generators running during evening hours! Thank you again!
Interesting experiment. Probably one of the most inefficient methods possible to create syngas. As a chemical engineer, I cringe a little bit at using syngas as just fuel. It's the precursor to a huge variety of chemical products from ammonia to methanol to Fischer-Tropsch gas-to-liquids products. An absolutely enormous amount of the world's energy goes into making that combination of H2 and CO. Now I'm curious what you could actually do with your small amount of atmospheric pressure syngas besides burn it. I've designed industrial scale low-pressure syngas plants, but I wonder what a hobbyist could do. I'll have to check some of my books.
I thought if some of the heat and light energy was recaptured, this would be a good generation method, but it's starting to dawn on me that it's still way too energy intensive to justify at an industrial scale. It's still a fun problem to me though haha.
I nearly jumped out of my seat when I had a think about it and took an educated guess about what was going on and it was right!!! :) Good feeling, good video
Nice experiment. If the Main Reaktion is H2O + C --> H2 + CO, the you are able to produce two moles of Gas per one mol of Carbon. Thats 2 x 22,4L per 12g of carbon or about 3700ml per 1g of C. Ohne Suggestion: Please weight you Elctrodes before and After, to See if the reaction is taking place . Greatings from Germany.
This is the best thing i've seen on youtube ever. You're really a God sent savior of the world. I see intermittent green companies using this to produce a constant load. GO GREEN!
This would really only be economical on an industrial scale where you have to find some use for the electricity a wind farm was generating through the night (as one example)
@@Nighthawkinlight I was thinking of energy storage for cold Nordic winters. The standard solution of burning wood involves the very tedious work of moving it around in the summer and keeping a fire going throughout winter. So a lot of households have already opted for gas heating. The components required for 20 seconds of 150A@20V aren't prohibitively expensive (caps or battery / solar panel). In the summer the sun is also plenty. Although these small bursts won't be on an industrial scale, one could calculate the solar panel area required to heat a household throughout winter. Granted, this direction of heating seems quite a bit more dangerous than playing with fire and there are ofcourse many other directions of efficient heating available which are inherently safe, but a lot of them require a big upfront cost.
@@CarbonFiberSpoon You wont be storing this anywhere cheaply enough to make it worth your while i guess. At least not in a scale that worth considering for seasonal storage.
Ben, just wanted to say thanks for the content you and all your supporters create. You and so many others are sort of the new 'Mr Wizards' of 21st century mass media. Keep up the great work continuing to bring us all such wonderful experiments that help us all understand how the world works.
LN2 would work, but only just barely. CO condenses at -192C and LN2 at -196C. For reference, oxygen condenses at -183C. Dry ice would not work for anything other than water vapor.
If you use any other type of gas without a heat exchanger, but just as a direct heat exchange process, then the other gas such as the LNG would vaporize and mix with the hydrogen and then you are back where you started except now it's mixed with a gas that has an even lower condensing temperature.
@@xvidavi Better long term energy storage, the energy density will of the storage system improves when larger, the stored energy can be transferred more efficiently to other storage vessels for powering cars (the energy density is much better for it as well.)
Love to know them temp of the flame...yes, please cook with that in a video. Even if it isn't an efficient method, you still could perhaps get a fuel for indoor cooking and heating from wind or solar in an emergency (if your home had no gas or electricity for days)
@@calvingreene90 Thats where this gas mixture falls short. It destroys steel and cannot be compressed into tanks the way pure H2 or propane can be. Maybe a fiberglass tank like most firefighters use would be okay.
SateenDuraLuxe I was wondering the same thing. People are asking about the cost effectiveness of producing this gas compared to the cost of the electricity it takes to make it. If you were getting your electricity for free by generating your own via solar, wind, or hydro it might be very cost effective...
Thank you for the link to the patent where it is stated that one of the uses for this device would be to provide the COHH gas to fuel an internal combustion engine without the need for problematic gas storage because the gas generation is fast enough to keep up with the instantaneous demands of a gas engine. But that brings up where is the electricity coming from, a large storage battery perhaps. I'm strugling to see how this makes sense.
Hmmm, you're generating hydrogen, oxygen and carbon. This looks similar to the production of syngas. So it's likely that you're not only making CO and H2, but also some of their reaction products. But what they wrote in the parent is bs: _"It is the applicant's belief that a mixture of carbon monoxide and hydrogen (COH2) is a gas which..."_
sasja de vries. Syngas is a bit safer but if you are going to try this you are probably better off assuming it is making CO and treating it accordingly unless you have a Gas Chromatograph handy. I was thinking about putting in a comment about it making some interesting byproducts. He would also be making carbon nanotubes which are a potential carcinogen. Got carbon monoxide also has a thing for metals etc so there is a lot of interesting chemistry in that reaction
@@glenecollins Well, syngas is basically a mix of mostly carbon monoxide and hydrogen. And THAT is exactly what he is making here, he is just making plain old syngas. However I'm not sure how pure that syngas is, firstly there are impurities in the water, secondly I'm not sure if the syngas turns into something else. Maybe the syngas is turning into another hydrocarbon because of the intense heat. In the patent they wrote this gas contains COH2 (formaldehyde), which is also toxic btw. And you're only concerned about the monoxide??? And no, you shouldn't treat this as Carbon monoxide, you should treat it as syngas (mix of CO and H2) with impurities. Hydrogen is way more dangerous than you think, it leaks right through plastic and it burns in any ratio with air.
@@kiyoponnn You are correct. Most patent applications are BS. People who really invent something often keep things secret and don't patent it so that no-one knows how they did it. And the dumbasses who can't make money anyway like to patent for the prestige and the bragging rights. The American patent office should be like the Japanese, German or Russian patent offices. They always reject these patent applications that don't invent anything new.
@@Nighthawkinlight to me, it's all about concept and efficiency. I've been a pack rat with purpose for a decade, finally got my own little homestead and the time to use tanks, tubes, motors and pressure vessels has come. Cheers* to a productive summer!
This was actually done during WW II, during the gasoline rationing in America and Australia. They just produced it with a wood gasifier. It had about 2/3 the energy density of gasoline, so once rationing was over, everyone went back to petroleum for the performance.
Not sure if it's possible for the alternator to provide enough power to keep up with gas production with this method. I have studied this for years with HHO, and think this method has too many losses. It would be cool to see someone try it, though I don't think you could generate enough to keep the engine running under a load.
Nice job! I first saw this gas back in the mid-90s, and a friend tested it found it to be fairly low energy gas, but fascinating and if you needed a gas flame this would be a great way to produce it.
When you went on to say that the gas was poisonous, I immediately thought of chlorine gas, and that you had salt water in the tank, but then you said it was rain water i was like, "ok, now i'm clueless", never would have thought that the carbon from the rods would behave like that under those conditions. Again a very cool video!
Nighthawkinlight: “there is a risk of electrocution, blindness” Me: eh that doesn’t sound interesting Nighthawk: and if those two things don’t get you, poisoning Me: oooh, you have me hooked, that sounds fun!
on woodgas production, I have mentioned before,on your motorized bicycle project, I suggest installing an arduino controlled carb (using electrically controlled valves) in this way a level of precision can be established. I hope you are continuing experimentation on this project.
@@Nighthawkinlight It does not seem like they need a catalyst. But i could also be wrong. EDIT: Sabatier's reaction describes that you need 300-400 °C and presence of a nickel catalyst to get methanol.
Good to have respect for electricity! In this case it's connected to an arc welder, which is low enough voltage to not be dangerous to touch. It *is* dangerous in other ways though - heat and ultraviolet light, mostly.
You sir, have never been in a box to think outside of. Lol I'm curious to know the data on electric energy usage vs fuel energy created. (Yes, I'm one of those nerdy people.) I've been watching your videos for years. You never disappoint. Thank you!
I've seen this exact carbon Arc gas power and engine which then energized the arc welder, effectively turning water into engine fuel, which also provided an additional output all of electrical load and heat and vibration.

Hello Sir I love the content you provide. Probably the best educational channel I've subscribed to on RUclips. Thank you for your efforts. I hope you're staying safe during these trying times.
Wow... I missed this 2 years ago (but saw your gasometer & woodgas vids). Interestingly, the output of this & your woodgas generator are CO & H2 (although I assume in different proportions). This is much cleaner.
Because of you, I am thinking about making a machine Two charged graphite disks rolling againar each other. Connected to fans that throw water in the spinward direction... Measure current drain, and maximize rotation speed - should also be auto striking when not spinning. I bet you are exfoliating graphene into that water. Nice byproduct for a maker :)
Wow this sure brings back my ninth grade chemistry class memory~ Pump water vapor through heated coal (without air, like how you made wood gas) you get CO+H2, this is in the textbook of ninth grade chemistry of mainland China,and it shows up in almost every exam, so a lot Chinese students know this pretty well.It seems weird to put this particular fact in the textbook, but it's there for a reason.This process as mentioned in the comment is called Fischer-Tropsch process and it's invented by Germans during WWII, to cope with the Germany's gasoline shortage.Not like America, both China and Germany have little oil but tons of coal, so in the old days China adopted this process to turn coal into gasoline to drive cars and engines(specially-made or modified for water gas), for a few decades(before 70s) the cars on the China street were drived by this stuff.So I guess it's in the textbook as a real life experience and an example of how chemistry could solve real problems.
I did this sort of thing decades ago, like 1986, using plain tap water. I did not burn the gas, but I did notice that it smelled much like Acetylene (aka Ethyne) from a welding tank. It seem likely that there could be some of that C2H2 in the output gas, especially since the UV (ultraviolet light) from the arc can split H2 into atomic hydrogen. I note that large gas clouds in space often have C2H2 in them, as revealed by spectroscopic analysis of starlight shining through the clouds. (Long-time subscriber, but only just got this video recommended in the sidebar. So many great things to look at, so little time!) @Nighthawkinlight
Nice experiment.Probably a good reason why it’s relatively unknown is the amount of energy needed to make it, completely offsets the amount gained. Still, a great example of the construction of molecules. Thanks for a great video.
If you are already playing with high-current arcs, why not try making Calcium Carbide to generate flammable gas? And you could try to make a chunk of silicon carbide, even though that doesn’t generate flammable gases. Still a cool material.
Aside from freezing, Tesla came up with a method of electrically charging gasses coming out one center aperture to get them to separate and enter other pipe apertures at staged distances. High frequency Alternating current was used and the voltage needs to be controlled to be high enough to produce the effect without causing an explosion.
Carbon electrodes, so I'm guessing some type of hydrocarbon like methane. Couldn't begin to assume what type of hydrocarbon precisely. Post video edit: Well, I certainly didn't expect that. It makes way more sense after you explain that the carbon is getting oxidized though, neat. After all these years I still learn something new with a lot of your videos, keep up the great work.
I will be interested if any of you know of a simple method to separate the mixture of gasses that this process creates.
well you could lower them to -195°c where carbon monoxyde would be liquid and dihydrogen still a gas, but that would be tricky
Was the gas chlorine
Molecular sieve maybe, even something like a balloon might work. It would be slow though.
maybe using density? i would figure out how to calculate the amount of carbon vs h2O produced and then figure out where the line between h2 and CO would be on the container. then use some kind of valve to purge off the amount of hydrogen slowly.
Molecular sieve like oxygen concentrators (the medical device might be easier to get ahold of) and liquid nitrogen generators use maybe?

@@Derived_One Potential energy - pump type hydroelectric plants, which work like any other hydroelectric plant (dam, difference of levels, water goes down from above, passes through a turbine, boom). They have, however a possibility to pump water upwards when there is lower demand for electricity in the grid and releasing them when the demand is higher. They play a great role in stabilising the power grid actually. Big downside - size, cost and need for water reservoir - not too many places you can build that, and if you can, the local environmental impact is very high.
The efficiency comes from the fact, that there is not much energy loss when pumping a liquid - and large machines are generally more efficient than small ones, so overall efficiency goes quite high.|
Fun fact - in such plants the turbine can work as pump and a generator as motor. No need for separate pump units.
Hope I have interested you a bit in the topic (of course if you did not know this already :D )
@@Derived_One when enough electric cars are on the grid that will be a pretty efficient short term store.
Long term storage would really be chemical or potential.
Thanks!
Love these experiments! 👍👍
This guy is awesome. Love your videos. I have always been a nerd that loves science and I often isolate myself from others just to do these things. I'm obsessed with these experiments. Keep up the good work.
Absolutely incredible! I had no idea that the heat of an arc could be used in this way! I was wondering about striking an arc underwater though, and glad I didn't, I had no idea CO gas would be generated.
dont be fooled, oh you already were? I was going to ask if you have heard of underwater welding but you were already fooled
For the separation of products you may use water shift reaction. Not a separation per se, but will yield one product, and IMO the more interesting one. And it will be great to see WSR in a workshop scale.
I know that the main products are monoxide and hydrogen, but the super high temperatures of electrical arcs are strange things and can produce unexpected complexity. I would like to see the product gas run through a mass spec to see what trace species were also produced. I bet you would see some methane, ethylene, acetylene, maybe even ethane in there. Recall that a simple spark in an atmosphere of hydrogen, water and ammonia produces a rich array of amino acids (Urey-Miller). I don't think anything as complex as that is being created in a setup like this (no time for it), but all the same, I bet there are interesting complex trace components in that gas, perhaps even exotic things like endohedral fullerenes.
Muonium when i used to arc charcoal under water , the bubbles did have a very strange smell to them.
Had the same expectation
The proportion of acetylene might be significant, considering that passing hydrogen inside a carbon rod electric arc is how acetylene was first synthesized.
Especially mixing in the fact he's using water that has organic components from the leafs in it.

How dangerous*
@@hunterjackson802 Yes
As far as I remember from my chemistry classes, Carbon Electrode breaks down to generate highly reactive carbon atoms under high temperatures which has the ability to combine oxy-hydrogen atoms to generate an into an hexagonal intermediate unstable molecular state, and finally, another nascent oxygen or hydrogen splices the intermediate species to generate methane, acetylene, ethylene, methanol, formaldehyde or formic acid, which can react back on the intermediate stage to generate a multiple combinations of hydrocarbons, aldehydes and ketones. So I believe its not a single species of gas produced, but a mixture of all probable organic molecules depending on the exposure time
*makes video on high power cannons
*makes videos on carbon arch torches
"Okay, this one is dangerous."

It must have been such a satisfying feeling seeing that flame for the first time, well done!
Mate have just recently stumbled across the wood gas concept and seen your videos about it and had to subscribe, definitely glad I did now!! You're a true "mad scientist" 😄, I love it!!
This is a really cool process, it gives me lots of ideas for what could be done with it on a large scale
Here's a probably wrong guess but maybe the gas could be some sort of hydrocarbon from the carbon rods and the hydrogen in the water
Well I was sort of close. Cool video though!
Yeah my guess was Oxygen and Methane
Bearcat Ben Mine too, but when you think about it, Methane burns in Oxygen, so the carbon Atom would rater have the Oxygen bound to it than the Hydrogen.
He made Syngas. I'd be slightly surprised if there isn't some hydrocarbon contamination in his gas. If he got the arc going in it, it may randomly produce hydrocarbons. Add some nitrogen, sulfur, a pinch of phosphorus and maybe a couple of other ingredients, and the arc would make some of the building blocks of life, like amino and nucleic acids, proteins, maybe lipids and misc. UVC light might be a better way though, a little gentler so it might not rip stuff apart as quickly as it is stuck together. Something like that is thought to be why some asteroids have some of that essential to life gunk. Such gunk, plus time, might be where life started on Earth.

I'd love to see you tackle making your own Vanadium redox flow battery. I've always thought they might be a great candidate for grid level storage as their scalability seems pretty good.
Getting vanadium is a bitch
I tried it 15 years ago! The idea was to scrap the particulate filter of a Diesel engine to make the carbon rods and use its generator when decelerating to create that synth.gas, which is then burnt while accelerating.
You can't keep the gas mixed for a long time, H2 is so much lighter than CO....
About that extra yellow-orange colour at the end; there is a possibility that glass got ionised by arc torch and released sodium ions in the gas mix.
Its hot enough
It's more likely that the sodium was simply present in the leaf strewn rainwater to begin with. Sodium is an incredibly efficient converter of various energy forms into yellow light (the d-lines), there's a reason it's been used in every street lamp in the world for the past half century up until very recently.
Oh like Nile Red's microwave plasma video
not really the glas because carbon rods for making light are doped with salt to change the lightcolour from something blue ish to warm white and this rods he use are clearly for arc lamps seen them before several times
@@incrediblemichael You don't know what you are talking about lol. Those are carbon arc rods for removing metal such as welds that need to be redone, or back gouging for weld prep. Those are not rods for acr lamps. I am a welder with 30 years of experience, and I have used those exact rods many many times.
Really interesting point about the yellow flame indicating sodium contamination. If you haven't already (I haven't looked), that might be a cool topic to explore: what different flame colors tell us about the elements being oxidized. Anyway thank you for the excellent video
Very cool! Look up Syngas or Synthesis gas, it's the same mixture that's been produced for over a hundred years by various methods.
Ah! Yes, someone else did identify it!
I've been bugging every maker-tuber I know to try making producer/water/syngas. Stoked for this.
The give away was the poison warning.
I have a 19KW solar system that I am going to go off grid with. The climate I will be in is not suitable for batteries.

7:22 his expression says so much about his love of science
This channel is so great for off grid living ideas.
Interesting experiment. Probably one of the most inefficient methods possible to create syngas. As a chemical engineer, I cringe a little bit at using syngas as just fuel. It's the precursor to a huge variety of chemical products from ammonia to methanol to Fischer-Tropsch gas-to-liquids products. An absolutely enormous amount of the world's energy goes into making that combination of H2 and CO.
Now I'm curious what you could actually do with your small amount of atmospheric pressure syngas besides burn it. I've designed industrial scale low-pressure syngas plants, but I wonder what a hobbyist could do. I'll have to check some of my books.
I thought if some of the heat and light energy was recaptured, this would be a good generation method, but it's starting to dawn on me that it's still way too energy intensive to justify at an industrial scale. It's still a fun problem to me though haha.
This is a primary hidrocarbon.
I know for the name bingo fuel by Naudin.
Interesting experiment.
Thanks.

Nice experiment. If the Main Reaktion is H2O + C --> H2 + CO, the you are able to produce two moles of Gas per one mol of Carbon. Thats 2 x 22,4L per 12g of carbon or about 3700ml per 1g of C.

It's official, there's a legit alchemist on RUclips
This is the best thing i've seen on youtube ever. You're really a God sent savior of the world. I see intermittent green companies using this to produce a constant load. GO GREEN!
Out of curiosity, have you calculated the cost of a single tank given your local price for electricity?
This would really only be economical on an industrial scale where you have to find some use for the electricity a wind farm was generating through the night (as one example)
@@Nighthawkinlight I was thinking of energy storage for cold Nordic winters. The standard solution of burning wood involves the very tedious work of moving it around in the summer and keeping a fire going throughout winter. So a lot of households have already opted for gas heating.
The components required for 20 seconds of 150A@20V aren't prohibitively expensive (caps or battery / solar panel). In the summer the sun is also plenty.
Although these small bursts won't be on an industrial scale, one could calculate the solar panel area required to heat a household throughout winter.
Granted, this direction of heating seems quite a bit more dangerous than playing with fire and there are ofcourse many other directions of efficient heating available which are inherently safe, but a lot of them require a big upfront cost.
@@CarbonFiberSpoon You wont be storing this anywhere cheaply enough to make it worth your while i guess. At least not in a scale that worth considering for seasonal storage.
@@CarbonFiberSpoon woodgas allows heating far from the wood
@@Nighthawkinlight then how cost effective. is it compared to a li ion battery
Ben, just wanted to say thanks for the content you and all your supporters create. You and so many others are sort of the new 'Mr Wizards' of 21st century mass media. Keep up the great work continuing to bring us all such wonderful experiments that help us all understand how the world works.
Try condensing the gas using liquid nitrogen or dry ice. That way you'll be able to see if its a hydrocarbon/CO or if you're just making HHO.
If it were HHO it would be a lot more explodey than what you see coming out of the burner. My gasometer probably would have gone through the roof
If it was just HHO, the carbon from the rods would have to recombine into soot, suspend in the water and turn it murky.
LN2 would work, but only just barely. CO condenses at -192C and LN2 at -196C.
For reference, oxygen condenses at -183C.
Dry ice would not work for anything other than water vapor.
If you use any other type of gas without a heat exchanger, but just as a direct heat exchange process, then the other gas such as the LNG would vaporize and mix with the hydrogen and then you are back where you started except now it's mixed with a gas that has an even lower condensing temperature.
Not surprised that its CO. Sounds like plasma steam reforming. Very cool video!
Next video, could you try running this fuel on a generator and or running a stove while cooking eggs or something.
making fuel with elecricity and then using it to generate electricity, its like a battery but with extra steps
@@xvidavi
Better long term energy storage, the energy density will of the storage system improves when larger, the stored energy can be transferred more efficiently to other storage vessels for powering cars (the energy density is much better for it as well.)
@@xvidavi
And a lower self discharge rate.
Love to know them temp of the flame...yes, please cook with that in a video. Even if it isn't an efficient method, you still could perhaps get a fuel for indoor cooking and heating from wind or solar in an emergency (if your home had no gas or electricity for days)
@@calvingreene90 Thats where this gas mixture falls short. It destroys steel and cannot be compressed into tanks the way pure H2 or propane can be. Maybe a fiberglass tank like most firefighters use would be okay.
2:14 it’s how you built your gas container about a year ago I think Ambro hats off and bro, my hat is off to you
Could you combine that process with solar panels to make a super cheap energy storage method that doesn't require spending thousands on battery banks.
SateenDuraLuxe
I was wondering the same thing.
People are asking about the cost
effectiveness of producing this gas
compared to the cost of the electricity
it takes to make it.
If you were getting your electricity for
free by generating your own via solar,
wind, or hydro it might be very cost
effective...
but these things are not free so you should factor in all the costs and efficiencies to be sure
Thank you for the link to the patent where it is stated that one of the uses for this device would be to provide the COHH gas to fuel an internal combustion engine without the need for problematic gas storage because the gas generation is fast enough to keep up with the instantaneous demands of a gas engine. But that brings up where is the electricity coming from, a large storage battery perhaps. I'm strugling to see how this makes sense.
Hmmm, you're generating hydrogen, oxygen and carbon. This looks similar to the production of syngas. So it's likely that you're not only making CO and H2, but also some of their reaction products.
But what they wrote in the parent is bs: _"It is the applicant's belief that a mixture of carbon monoxide and hydrogen (COH2) is a gas which..."_
The applicant is a moron, and this is a useless patent
sasja de vries. Syngas is a bit safer but if you are going to try this you are probably better off assuming it is making CO and treating it accordingly unless you have a Gas Chromatograph handy.
I was thinking about putting in a comment about it making some interesting byproducts. He would also be making carbon nanotubes which are a potential carcinogen.
Got carbon monoxide also has a thing for metals etc so there is a lot of interesting chemistry in that reaction
@@glenecollins Well, syngas is basically a mix of mostly carbon monoxide and hydrogen. And THAT is exactly what he is making here, he is just making plain old syngas.
However I'm not sure how pure that syngas is, firstly there are impurities in the water, secondly I'm not sure if the syngas turns into something else. Maybe the syngas is turning into another hydrocarbon because of the intense heat. In the patent they wrote this gas contains COH2 (formaldehyde), which is also toxic btw. And you're only concerned about the monoxide???
And no, you shouldn't treat this as Carbon monoxide, you should treat it as syngas (mix of CO and H2) with impurities. Hydrogen is way more dangerous than you think, it leaks right through plastic and it burns in any ratio with air.
@@kiyoponnn You are correct. Most patent applications are BS. People who really invent something often keep things secret and don't patent it so that no-one knows how they did it. And the dumbasses who can't make money anyway like to patent for the prestige and the bragging rights.
The American patent office should be like the Japanese, German or Russian patent offices. They always reject these patent applications that don't invent anything new.
So cool man! I'm a tinkerer/welder/fabricator. Thanks for the ideas! First video, looking forward to getting some tips on my gasifier.
My gasifiers are pretty primitive. I'm considering a more polished build this summer.
@@Nighthawkinlight to me, it's all about concept and efficiency. I've been a pack rat with purpose for a decade, finally got my own little homestead and the time to use tanks, tubes, motors and pressure vessels has come. Cheers* to a productive summer!
In the next video: running my car on carbon monoxide!
Pls do that
If we could just find a way to store it in a small tank, then I would do it.
This was actually done during WW II, during the gasoline rationing in America and Australia. They just produced it with a wood gasifier. It had about 2/3 the energy density of gasoline, so once rationing was over, everyone went back to petroleum for the performance.
Not sure if it's possible for the alternator to provide enough power to keep up with gas production with this method. I have studied this for years with HHO, and think this method has too many losses. It would be cool to see someone try it, though I don't think you could generate enough to keep the engine running under a load.
Nice job! I first saw this gas back in the mid-90s, and a friend tested it found it to be fairly low energy gas, but fascinating and if you needed a gas flame this would be a great way to produce it.
guessing probably something like acetylene from the carbon rods
No, mostly Carbon Monoxide and Hydrogen.
i also guessed acetylene. I'm glad I wasn't the only one.
When you went on to say that the gas was poisonous, I immediately thought of chlorine gas, and that you had salt water in the tank, but then you said it was rain water i was like, "ok, now i'm clueless", never would have thought that the carbon from the rods would behave like that under those conditions. Again a very cool video!
You seem like someone that took a whiff of some chlorine too, it's unforgettable isn't it.

The reaction between hydrogen and carbon monoxide produces methanol . CO + H2 = CH3OH
That would be pretty interesting to form in a secondary reaction
I assume it requires a catalyst?
@@Nighthawkinlight It does not seem like they need a catalyst. But i could also be wrong.
EDIT: Sabatier's reaction describes that you need 300-400 °C and presence of a nickel catalyst to get methanol.
It can be done but it's really an industrial process. The reaction takes place over a copper and zinc oxide catalyst at 50-100 atmospheres and 250°C.

Epic video my friend, thank YOU for making it and sharing ur knowledge with us.
5:42 you turned me nervous when you started to touch the electrodes
Good to have respect for electricity! In this case it's connected to an arc welder, which is low enough voltage to not be dangerous to touch. It *is* dangerous in other ways though - heat and ultraviolet light, mostly.

Wow... I missed this 2 years ago (but saw your gasometer & woodgas vids).
Interestingly, the output of this & your woodgas generator are CO & H2 (although I assume in different proportions). This is much cleaner.
Because of you, I am thinking about making a machine
Two charged graphite disks rolling againar each other. Connected to fans that throw water in the spinward direction...
Measure current drain, and maximize rotation speed - should also be auto striking when not spinning.
I bet you are exfoliating graphene into that water. Nice byproduct for a maker :)
Wow this sure brings back my ninth grade chemistry class memory~ Pump water vapor through heated coal (without air, like how you made wood gas) you get CO+H2, this is in the textbook of ninth grade chemistry of mainland China,and it shows up in almost every exam, so a lot Chinese students know this pretty well.It seems weird to put this particular fact in the textbook, but it's there for a reason.This process as mentioned in the comment is called Fischer-Tropsch process and it's invented by Germans during WWII, to cope with the Germany's gasoline shortage.Not like America, both China and Germany have little oil but tons of coal, so in the old days China adopted this process to turn coal into gasoline to drive cars and engines(specially-made or modified for water gas), for a few decades(before 70s) the cars on the China street were drived by this stuff.So I guess it's in the textbook as a real life experience and an example of how chemistry could solve real problems.
I did this sort of thing decades ago, like 1986, using plain tap water. I did not burn the gas, but I did notice that it smelled much like Acetylene (aka Ethyne) from a welding tank. It seem likely that there could be some of that C2H2 in the output gas, especially since the UV (ultraviolet light) from the arc can split H2 into atomic hydrogen. I note that large gas clouds in space often have C2H2 in them, as revealed by spectroscopic analysis of starlight shining through the clouds. (Long-time subscriber, but only just got this video recommended in the sidebar. So many great things to look at, so little time!) @Nighthawkinlight
Nice experiment.Probably a good reason why it’s relatively unknown is the amount of energy needed to make it, completely offsets the amount gained. Still, a great example of the construction of molecules. Thanks for a great video.
If you are already playing with high-current arcs, why not try making Calcium Carbide to generate flammable gas?
And you could try to make a chunk of silicon carbide, even though that doesn’t generate flammable gases. Still a cool material.
Aside from freezing, Tesla came up with a method of electrically charging gasses coming out one center aperture to get them to separate and enter other pipe apertures at staged distances. High frequency Alternating current was used and the voltage needs to be controlled to be high enough to produce the effect without causing an explosion.
