- In this video I build a wood gas storage device that cleans and pressurizes the gas all in one! Thanks to my sponsor Squarespace you can make a great website easily! Check them out at: www.squarespace.com/nighthawk
In case you missed it, here's my last video where I built the gassifier used in this video to make my gas: • Testing A Better Wood ...
The wikipedia page on gas holders has some great visualizations and images of commercial gasometers: en.wikipedia.org/wiki/Gas_holder
Thanks to all my Patrons for helping me make these videos! A special thanks to my top Patrons: Syniurge, Matthew Leitzke, TheBackyardScientist, Enzo Breda Lee, John Johnson, & Thibaud Peverelli! / nighthawkprojects
So what is wood gas good for? A lot of you have asked that question. The main point of wood gas is to turn a renewable fuel like wood/plant matter into a form that is compatible to be burned by modern technology like cars, generators, stoves, etc.. Wood gas is a fuel that can be made by anyone with simple equipment, and can run a gasoline engine with only minor modifications. The process I use in this video to make it produces a very clean result, but is not the most efficient way to make large quantities of gas for immediate burning. I'll be demonstrating other methods of wood gas production in future videos.
Thanks for watching!
If you missed my last video where I build the gassifier used for this project, you can watch it here: ruclips.net/video/HQIW4dVVokE/видео.html
Who would miss one of your videos?
To bubble the water from the bottom to the top means that the gas needs to have enough pressure to force the water out of the tube. That's more pressure than my gassifier generates in this setup.
silicone rubber is a thermal set, so it is pretty heat resistant
I think a shower head hose might be able to survive the heat better.
You should make an airtight crockpot to heat the wood inside, leading to a canister to store the gas. Something I found online: Higher temperatures improve hydrogen yield in the gaseous product while CO yield decreases. Under nitrogen atmosphere, after 2 s at 950 °C, 76% (daf) of the mass of wood is recovered as gases: CO, CO2, H2, CH4, C2H2, C2H4 and H2O. Tests performed under steam partial pressure showed that hydrogen production is slightly enhanced.
Instead worrying about what type of tube you use , you could use a condenser to cool the gas before it reaches the tube
I was thinking almost the same thing...just use a cooling system on the pipe and hose like the worm in a still
And condense out tar that blocks it all up.
I'd say just run it though a water column. It'll cool the gas and also remove the impurities.
Absolutely correct! Coil condenser with a collection pot to capture contaminates at the bottom works very efficiently.
I've used this method for years to convert acetone to diketene with great success.
Isn't the condensed liquid diesel? so a diesel collector in the middle will prevent condensation in the pipe and melting the pipe.
I like how you keep people from clicking away on your sponsored outro with your adorable bird
Gabriel Schoene in a possessive context, it's 'your'*.
Also I agree, that adorable bird prevents me from clicking away!!!
Marcus Polus read again, I said your.
You're right because you used your brain to realize your is the right word..
How about that there their they're word eh?
Gabriel Schoene I'm looking right at it, it says you're!
Also, I was trying to be helpful, didn't think I could write it any nicer!!!
Lol, he said both "your" and "you're" in the sentence.😂😂
Marcus Polus I didn't intend to sound rude.. but I see it now. Not of the first your, the second your in the comment is incorrect.. good catch!
I like how pretty much every by-product of this process is a useful material. The charcoal has lots of uses, the tar can be used to make wood rot-resistant, the wood gas is a decent fuel. There's really no waste.
Charcoal ash can make soap, and the chemistry goes on forever
and i can grow my own fuel . and it also grows naturally . just takes a bit of work thats all
@@MrRasZeein medieval times people had dedicated parts of their forest for firewood, idk how it’s called in English but in Dutch it’s called “kreupelhout”. They had fast growing trees that they kept short and guided into growing many sidebranches, these could then be harvested yearly for firewood in the winter, and then next year the tree had made new branches that could he harvested. Saved people a lot of trouble, as they where usually close to the farmstead/village and no need to end the lives of trees just to get firewood.
@@rubenskiii sounds like what I'd call a wood coppice. That method of regularly harvesting wood can result in the roots and base of the tree living for centuries!
@@ianwise2457 yes! That was the word i was looking for.
My goodness, you are really clever using the gas pipe. And using the epoxy to seal the bottom and the seam seal. Great job fella too.
The look of pride on your face was so genuine in the intro :D
i love the proud smile during the burn at the end :)
AHAHAHAHAHAHAHA
Yeah! It was most effective than his last attempt with the aquarium ^^
He reminds me of my father
Fr fr tho I said the same thing
We had three massive gasometers in my town, a few minutes walk away from where I live, they were a sort of landmark you could see for miles. I miss them oddly enough.
Just one dude who’s way into gasometers
In my city in Germany they just got them a different purpose, they are now exhibition rooms for museums and a restaurant.
That's so cool that you read all of the comments! I love how meticulous you are in your projects and how you're always showing where things didn't go as expected so we can learn from that too.
His smile when he turned it on and it worked, priceless :)
I absolutely love how simple and effective this is. Anyone and make an over-complicated solution to a problem, but it takes real genius to make something simple and elegant
Genius?yes sir and I bet you he read Tesla's Colorado note's-

*GAS
Why oh why on earth would I watch any other RUclips! 2 years it took to find you.. a $20 wood gasified camp stove brung me here. Thanks
I don't know about anyone else, but this kind of stuff fascinates me. I can't wait to build one of my own. People like you need to be running this country. Take Care.
7:05 the condensation is a mixture of wood alcohol (methanol), gasoline, tar and diesel. All of them are also valuable. You can set multiple filtration setups to collect them as well.
how would you separate the four...also is the water in the gasometer tainted in anyway?
Fractional distillation
Could actually be harvested with some water-cooling of the pipes, perhaps a spiral chamber with an outlet, then the gas passed on to the gasometer will also be purer but of course also denser, so perhaps you'd need a spring or something to lower the pressure in there, basically sucking the gas in.
Tube with in and out connection, cooled by water, so it condensates to pipe surface and collects on the bottom as a pool, witch can then be with regulated flow valve let empty to container.
Separation would be using standard oil industry techniques of fractional distillation as it was mentioned, where start product is heated and released to chamber. Due lack of oxygen it wont burn, but turn into gas. Chamber has several different levels with different levels of heat. Gasoline or methanol is easiest to turn to gas and will float on top chamber, where as heavier oils that take more temperature to turn into gas will condensate on lower levels, where these can be collected to separate containers, filtered again and put on use.
I would consider 'cracking' the distillate while it's still a avpour by heating further over some kind of catalyst. That way you will get more gas from the liquid portion, so more yield of usable gas.
Silicone tubing is good to have around. It's short term temperature resistant to well over 300°C, long term to about 200. It won't melt ever, and if it starts to discolour, it's degrading or basically slowly burning up.
Vinyl has a fairly high melting temperature... i forget... but it's a very hard plastic, so tubing must contain plastifier, which potentially has little effect on melting temperature but gets glass transition temperature way down. Incidentally this is why it's becoming softer when it heats up. At the start of the video i guessed that it would survive and hey happy that it did.
Hey Siana! Singularity Viewer user here.
He needs stainless flex hose.
Beautiful build. Many years ago, I played at my cousin’s house that was close to a coke plant. It was alway fascinating watching the gas storage tanks rise and lower, and I always wondered what was going on. At 70 years old, now I know. Thank you.
I am enjoying this video series. My late Grandpa and his late brother converted their car to run on wood gas here in Melbourne Australia during WW II to get around the petrol rationing problem. Back in the late 70's I can recall a couple of gasometer tanks near Heidelberg being dismantled as the town gas supply system matured.
His face so friendly, especially when he smile :P
Agree
I know this was part of my suggestion on the last video and apologize for the repeat. If you add a copper coil and an intermediate collection can right after the coil but before the tubing you will cool the gas significantly before it hits your tubing thus increasing its life span and you get the added benefit of collecting the condensate before it hits the storage container. Similar to how alcohol is condensed in a still.
cooper and brass can be considered as catalyst as well and purify the gas
But the tar by-product would condense and cool within the condenser coils, whereby clogging the system and eventually causing a back pressure into the gasifier can... please tell if I have this wrong?
@@johnjulie6657 yes you are right , i had the same problem with ,mine . the solution was a cyclone filter and wood chips and shavings.
@@johnjulie6657 a very low tech way of fixing that is putting a longer outlet pipe from the furnace. And taking a cue from natural gas piping place a T fitting with a pipe going down. Place a cap or preferably a valve at the end. Anything heavier than the gas will sink into the down pipe. Every now and then crack open the valve to empty it out.
Your videos are my favorite to watch. I was inspired to make a storm glass using your methods and did so. I gave it as a gift to my dad using a nice glass jar that I found in a grocery store. Thank you for your for everything you do and i'm always excited to watch more of your content. Cheers from Seattle.
I really liked this video!
You can get around the flexible tube by having your inlet and outlet pipes enter the BOTTOM of the water chamber, and then rise through the water into the headspace of the floating chamber. Gas will come in the bottom, rise through the tube in the water (or you could have it bubble through the water, but your gas generator would have to be above the water line) then it would either float the upper chamber, or pass out through the outlet pipe (depending on gas demand).
This is the first wood gassifier that i have seen with any type of accumulator, and I must say, it has given me a lot of ideas!
Great suggestion
im amazed on how dedicate you are, amazing job!
you improved the desing a lot this time
I love how you are able to make simple, easy to reproduce designs in your projects. You are my favorite RUclips content provider!
Using that double walled pipe and end cap is brilliant!
I was looking for a light weight solution, and this seems very suitable!
A suggestion. The condensate is called wood vinegar and has many agricultural applications. Thanks for the work you've done to explain this process so well!
I love the wood gas content it's fascinating how something so simple could be used for just about anything.
You should try using the wood tar for something. Maybe make a 14th century ship with it. ;)
It's creosote. A few decades ago, it was used to treat utility poles, railroad ties, etc. Here in the USA, general sales of creosote was banned by the EPA in 1986.
@@gyrgrls damned epa
John Bond why was it banned? Just curious since I honestly don’t know anything about it.
@@ThatOneFriendlyDude It's extremely carcinogenic. It's roughly thethe same as cigarettes' tar, just more concentrated, it'll give you all sorts of nasty cancers. Also, every kind of heavy metal found in low amounts in the starting wood will be concentrated in it.
@@gyrgrls Nastiest splinters you will EVER have in your whole life.
The smile in your face when lighting the torch - priceless :)
That was the best design and explanation I have seen about gasifiers and a gasometer. Very well done! Thank you!
If you run your gas line in the bottom it can bubble up through the water to help clean the wood gas. It would also leave the top of the moveable sleeve unobstructed. In the late 80s or early 90s I saw an article in Mother Earth News. A farmer was running a methane digester with manure. He was using a similar gas collection device only massive. It was so big it had a pulley and counter weight system to make the inner bell neutrality buoyant. I believe his outer tank was concrete. I seem to recall it was as big around as a silo. With a system like that you could change the counter weight as a way to adjust the gas pressure.
It's really awesome seeing you doing so much experimenting with wood gas. Like I said last time, try using ordinary trash, like paper, cardboard, cereal boxes, old rags, etc. as production fuel at some point. It may be a bit harder to use with your current setup, but I think it would be worth it to see how much gas you could produce from it compared to regular wood.
And on that subject, it might be interesting to see how much you get from fresh wood compared to dead and dry wood.
Also, bringing your adorable bird in to give us incentive to watch the sponsor bit of your videos is really clever, and I don't regret watching it one bit. I'd love to see an off-topic video just about your bird at some point. It's super cute, and it looks like you take very good care of it. ♥
I think the amount of wood gas produced is equal in fresh or dry wood, if the wood is otherwise the same. The potential for gas produced is not ruled by freshness, it just means it has more water. At least that's what i have always thought. Before the wood will pyrolyze and gasses will exit the wood material, water has to dissipate from it and that takes time and energy so the process is just slower.
That could actually be a test in itself; how much dryness affects before the wood gas starts to produce.
And vinegar
Great video! I'm currently conducting a research project on the potential of biomass energy around the world and stumbled on your video. How great to know anyone can learn how to make these things!
I’m so happy I stumbled across this channel, DIY on topics right up my alley.
Get some PTFE tubing. It's the most temperature resistant material that's flexible. You need specific connectors for it, but it will work up to 500F.
Great tip!
Or lab rubber tubing, a lot cheaper, from amazon or eBay is easy to find
Silicone tubing would work
You could put the inlet into the bottom tank, but you still need a small amount of flexibility
A gasometer normally has 3 walls, the middle one being the top, the cavity is normally filled with oil iirc
If you fill the main chamber with water initially, then when you get sufficient gas you could drain main chamber (bottom inlet would help with this), that would give you more room for gas, and lighter to carry
PTFE is not THAT flexible and not THAT temperature resistant, it starts to slowly give up around 250°C. Silicone beats PTFE on both accounts.
PTFE is perfectly flexible and suitable for the application shown in this video. It will hold significantly more pressure as a result of the increased stiffness, which could prove useful if weight is added to the gasometer to compress the wood gas. Additionally, the melting point of PTFE is 327 degrees C compared to the lower 300 degrees C of silicone rubber. Either one is better than the vinyl(?) tube in the video.
I believe every single commercial should have the person explain the product while playing with a parrot in the foreground.
A really good system, producing two fuels: the gas and charcoal. Nice!
There's methanol being produced as well, hes just not collecting it.
Thank you so much and an amazing video. We have started our engineering project on alternate fuels and have taken this as a guidance. Keep it up. And thanks a lot
Now you need to make it fuelled by a solar concentration lens so that you dont have to waste the wood to heat the fire, it can all go into making gas. Then you need to compress it and store it and run an engine on it.
Or connect it to a furnace that is already going to be producing pyrolysis capable heat.
As always it is great to see your progress and learning about this process, but best of all is your beautiful black headed caique, they are my favorite bird to ever have had as a part of my life.
I like how you can see the gas flow through the vinyl pipe, but I think a insulated hose like the type that goes from the water source to the toilet might work better and be easy to retrofit in your application. Great job!
Great job! Possibly add a radiator or another water tank to bubble the gas through to cool it off before reaching the vinyl tubing. This would also help with purification.
You're still My favorite DIY/Science Channel. Keep up the good work.
Braided steel cables (the ones meant for hot water hookups) or PEX (polyethylene cross link) tubing can't handle combustion temperatures but they are at least more heat resistant than vinyl and should have common links with standard plumbing fittings.
Excellent presentation, love what your doing. I saw somewhere,where they reckoned the USA has enough biomass now to replace 67% of the fossil fuel it uses !
Wow, that burns cleaner than I expected. That system is worth refining and scaling up.
You could put in a dirt pocket or drip leg (used in the piping trades) to collect the tar as it goes through the tube, then you could just blow off the tar and condensate to keep that tube from getting clogged over time!
Really like this series and can't wait to see what you have planned for the wood gas.
the build is really informative. i have some ideas for improvements though like i didnt see a pipe leading into the water i dont think your filtering the gas all that much without it going into the water first. if you do put the pipe on it and you want the cleanest gas you can get i would recommend a diffuser of some kind at the end of the pipe which will increase the surface area of gas touching the water. i was looking for a way to contain some gases i intended to make soon i love this idea thank you so much for posting it i love your content.
i like how you alwas seem so happy when you do things!! its like you not sure if it will work that just happy as heck it did!!
He always has a little smile. It's so cute, really brightens my day.
THIS IS QUALITY CONTENT...... Marvelous work.. bro .... And very educative...
I was hypnotized by your project! Very cool one! I come very late but you could use PFA or PTFE (resist around 220°C and chemicaly inert) tube instead of vinyl
Always enjoy watchin your videos this old tech will has ta start comin back tye way prices keep goin lol wonderful build to night o found an old metal fuel can an stuffed it full of shavingsan set it by the fire an took a broken broom handle an tookit to the band saw an stuck it inside the opening of the fuel tank an lit the smoke an my goodness it worked! Great video !!!
I'm loving these wood gas videos! keep em coming!
Thanks that was very well done and a good insight tutorial. I can see some cool off grid uses.
The gas will self clean with or without water. I build gasifiers and I use a design that I came up with that I call a expansion tank that works on the same theory as air conditioning and Refrigeration where you have gas passing through a small tube into a large chamber where it cools down due to the expansion of the woodgas and while it's cooling down it's losing humidity in the gas along with other contaminants that will flow to the bottom of the expansion chamber. I also use a traditional method a passing it through filter media but I use a tri-filter setup to further capture water and humidity along with other contaminants in the gas. What you built works really well especially for a demonstration but it would be impractical for running an engine because you'll need a larger volume of steady wood gas for power production even for a home setup. You made a really good demo video. Thanks for the Post
Cool video man! You might try adding a scale in inches with a permanent marker down the side of the inner chamber to help gauge the amount of gas being produced or used. It’s great to see that people are still interested in this kind of tech.
Fantastic work. You did a great job on this build and video!!
Thank you for posting this informative video! Your system would be great for people living off the grid.
I'm obsessed with this! I already make charcoal from willow on a small scale and it never occurred to me to catch the gas for later, could you possibly do a short video on a diy way to clean and condense the gas into methanol and maybe it's potential uses too? Thank you for all you do on this channel it's amazing to sit and watch through it all.
Get a burner and use it to cook food/bbq
I really like your recent wood gas projects!
Not sure if this has been mention but a small heat exchanger before the tubing would stop any danger of it melting the tube I have used similar distilling lavender oil just a tube the same as the top tube with a water jacket fitted around it you can either have a pump set up to move the water around or just make a water bath and just top up with cool water occasionally to keep it cool. This is also a great idea for storing hydrogen from a solar electrolysis unit as well. Thanks for some great ideas
Ciao dall' Italia ,ogni volta che guardo questo ,mi piace sempre di più
What a great video, glad you already did this! Glad to know it also burns off the carbon monoxide. Would really like to use food scraps and wood to fuel our cooking and have the luxury of gas cooking instead of electric which is bad for our clay pots. Your videos are so well done!
I loved how proud you looked when it worked.
I work with systems that measure exhaust gases from combustion engines. Those gases are hot and need to be kept at temperature to avoid condensation. To keep the gases heated we use so called flexible heated lines which use PTFE or PFA tubing inside, PFA being more chemically resistant (as far as I know). As you don't need to keep the gas heated, the tubing itself should be sufficient. It's not as flexible as vinyl tubing, but I'm confident you can figure something out.
NightCaiqueInLight
Bingo, new subchannel name for bird antics.
Stunning video, very informative and done with a great understanding. Well done !!
Use bungie to compress it and put a hardline into bottom of your gasometer with a line running inside the inner tube to eliminate the need for a flexible line. Also put a box inline between stove and gasometer to collect tar. This is awesome. Thank you.
Those experiments are awesome, and I can't wait to see what will happen in the future, indeed 😍
About tubing, I know there are some kind of silicone pipes which are capable of dealing with some high temperature (up to around 300ish C, which is about 500ish F), so you should be able to find something (but I see also a lot of comments in that sense): but I live in Italy so I can't tell for sure where to find those things in USA (except something like ebay, amazon or similar)
More than that, have you considered putting a longer piece of tubing (like 4-5mt/12-15ft) which a part is submerged in some cold water? This might help both with condensation and lowering the overall temperature of the outgoing gases.
5:18, the tube I would suggest using would be 100% Silicon. It should be rated for at least 450 F vs Vinyl Tube's 150-175ish F. It's also non porous so in theory it should be easier to clean all the soot buildup off of too. Oh and it's very flexible.
TrollFaceTheMan could he also use some metal braided lines? He could probably get some at an auto parts store
Riley McDowell, good question there are two big factors I would consider with that. The first being because they are opaque it would be much harder to tell what is going on inside them so visual assessment of gas production would be impossible for the tubing.
The other concern I'd have is though many are made to be rust resistant would the heat or even the byproducts like soot, methanol or things like potassium/sodium/calcium carbonate that accumulate over time in the tube affect that?
Polymer tubing for laboratory glassware use, Tygon for instance, might be pretty good contenders as well, if a little more expensive, assuming one can strike a good balance between flexibility and resistance to heat and chemical attack.
Amazing. If we take a heavier metal tube for the inside. It will act like weight and so the pressure will be greater. You have given me thoughts on a new project. Thnaks a lot for your videos. Keep them coming.
Hi I'm Troy from Australia I'd like to say thank you im unable to work full time so I have little money I'm renovating my tiny home . every little bit helps . thanks you.
If you want fixed metal pipes you could just install a thin U shaped metal tube that goes down trough the water and up above it. It's essentially filling the tank from the inside, not trough a valve.
I'm not sure how well that would work, since the pressure from the wood gas production would have to push the water out of the U shaped tube.
@Rafael Dos Santos
That's what it is doing with the current setup too. So it should be fine. I'd go with the internal tube.
Rafael has a valid point. A long Tube surrounded by water will pretty much act as a condensator and collect moisture from the wood, just like the PVC tubing, but worse.
Attaching a small reservouir at the bottom would solve that problem easily and with no big effort.
Dear NightHawkInLight,
I have come up with a few cool things you could make a video on using wood gas.
1. Compress cleaned gas into a tank and use it in a grill or gas lantern.
2. You could run a small generator off of it and/or see how big of a generator it can power.
3. Make oil and purify it into gasoline/ diesel fuel.
4. Run a propane fridge off of the gas
5. It would be more work but a go kart running off wood gas would be cool. It could use compressed gas.
I don't think a propane fridge will work. Any stove will though with an appropriate jet.
Thanks for the video. I learned a lot. I am going to see what your sponsor has to offer. I hope they have a communication system to see and hear the customer. Look forward to your next video. Take care my friend.
What a great video. Loved the simplicity. Brilliant sir!
Maybe you could add a three way connector with a collection vessel to recover the liquid that condenses out of the wood gas? It's going to be mostly water at first, but should also contain a variety of hydrocarbons and aromatic compounds (wood-tar creosote). These having low miscibility with water, they should separate and could in principle be easily recovered.
Creosote is a cool substance, with some interesting uses, like treatment of wood.
or also burn it if you atomize it like with kerosene or most oils.
Terpenes as well if gasifying pine wood.
A water trap.
The brown liquid can be fractionally distilled to recover the methanol in it.
Not sure on other tubing you could use but if you extended the metal pipe after the 90 degree bend it will move your current pipe further from the fire and also let some of the heat the metal conducts to dissipate as well. Maybe extend it close to a foot but I figure any distance will help the further the better. Also what about letting a damp rag lay on the pipe for even more cooling would also help i would think
It'd love to visit this guy one day. It's be amazing to see all the stuff he'd built and have a stimulating conversation.
Toda propuesta que fomente la conservacion del ecosistema, debe ser aplaudida y apoyada. Me encanta
Any proposal that encourages the conservation of the ecosystem must be applauded and supported.
It would be a great idea to compress all of collected and filtered gas with an old refrigerator compressor or a modified bike pump (I've seen people making pumps out of pvc pipe that are able to produce more than 100psi) into some pressurised container for later use. Your low pressure container is great for collecting gas before it could be compressed
Compression rates are not good. I had the same thought. I found that a propane tank would only get a car 2 miles on the road.

@@ellenorbjornsdottir1166 I'm not sure what you're asking. But form the various websites describing vehicles running of wood gas it seems that the production of the gas was produced on sight directly feeding the engine. Also, the efficiency was equivalent to gasoline efficient vehicles, including transportation of the wood fuel.
p.s. I'm no expert on this subject, although I'm indentured by it. Having said that, I don't think this is an alternative as a replacement of the gasoline engine i.e. "The Green Deal." There's just not enough of the feed stock around, just like ethanol. There are some plants worldwide operating on this fuel because they have a feed stock of waste from the products they harvest. Also FEMA has designs for producing wood gas for generators. but it's not meant as a replacement of the electric grid, rather it's to compliment it during emergencies when the grid is down.
awesome job as usual, ben!
You could probably keep the vinyl tube if you replace the straight tube with a copper coil which should use its surface area and the wind to cool off the gases enough to not melt the vinyl tube. Great channel, BTW, I just came here from Applied Science and just subbed.
I did a lot of r and d on gasification back in the day and we used a much larger gasometer and gasifier. We had to stack lead weights on top of it to get the pressure to run a small generator.
I think you can use a coil of copper pipe to cooling off the gas a little before it enter the plastic pipe? That way the gas will not too hot to melt the tube
Great video! I love your style of making videos!
I am working on something really similiar for my oxyhydrogen generator. However, I am also trying to store it under a slight pressure by placing a 10 kilogramm weight on top of the tube, so that more gas fit's inside.
Make sure that you separate the gasses and store them in separate containers. Storing oxyhydrogen together in a tank like this would be an explosion waiting to happen.
There are a few videos on youtube where people explain how people died because of compressed oxyhydrogen being so volatile and exploding
NightHawkInLight Of course I know that, and I already made a lots of experiences with oxyhydrogen in the past. Storing about 5 liters is really no problem, its not that huge explosion, compared to other explosives. Seperating the gases using gravity works a little bit and reduces the amount of oxygen in the mixture, however, there is still enough left for a slow combustion.
So I am going to find another way of doing it🤔☺️
Freizeitflugsphäre it's pretty easy to separate the two gases if you're generating it through electrolysis. You use a wide basin of solution, and use separate catchment containers above the anode and cathode. You can even use two separate containers if you have a solution-filled tube connecting them. The hydrogen reservoir will need to be twice the volume of the oxygen one.
James Petersen But thats efficient as hell
love the efficient water-seal below the gas.
I like this video a lot! It's simple and interesting.
I might be wrong about the physics on this, but I think that if you were to use a heavier "rising" collection tube, it should force the gas to be more compressed, meaning you should be able to collect more gas in the same space
Yeah I was thinking about the same thing but the valves must be able to handle the pressure too without giving out
I love your collector.
I'm wondering about the chemistry of the water over time as it becomes saturated with tars and other combustion byproducts. The viscosity must be increasing and at some point will need to be exchanged. After a number of runs check to see if there is stratification or settling of particulates. It might be evaporated to reduce the volume. The byproducts may also be environmently detrimental if not hazardous. Then again if in fact there is a substantial solid component when dried it might be combustible and used in subsequent cycles.
It's combustible and it can be broken down ( cracked ) to make liquid fuels similar to diesel & gasoline.
Nice video. Good job. It would be great ich you could turn this gas with the fisher tropsch synthese into liquid hydrocarbons. As a catalysyst i would take cobalt because it wont oxydise like iron. The reaction also works on 1 bar. You also need a temparatur from 150-300 degrees Celsius. You wil get mostly methan and a few hydrocarbons. The gas should be cleaned before use. Sorry for for the mistakes in the text. I have got english at school for about two years
You look so happy. I'm happy for you. Great video.

You make the coolest stuff
Sweet gravity bong bro
When you do the burn tests, should add a venturi mixer like the head of a propane torch so you can pre-mix the air and fuel before igniting it, much more satisfying flame that does not need a constant ignition source!
Nice project! Two ideas: use more metal tube before reaching the vinyl to cool the gas down and limit the condensation? And secondly, can wood gas be compressed safely? What about adding a weight to the top thing of the gasometer (like, weld some random stuff to it or put a lead weight around the tube?) so you can fit more wood gas in a smaller volume
Could you put a condener coil(similar to a reflux alchohol still) on the upright brass pipe, to lower the temp of the gas. Having it on the upright would also hopefully allow any tar to fall back into the gasifier, maybe.
i could say that every video from you. irealy like your kindness and your passion to your work. i can see, when you are burning your fuel that that is a true succses to you. Please go on with your work - it deliveres a great message like styropyros videos for example, that learning - especially learning by doing is a good way of expanding our knowledge.
are you planing to pressurise it until its liquefaction and fill it up in cans?
Thank you for the heads up on the wood gas storage.
Great video. Instead of vinyl use copper tubing. You could drop it vertically - parallel to the gasifier but away from the heat of the gasifier. Form it into a trap loop upward or a small coil. The more surface area of the copper the less heat that will be in the gas coming out the end which can be a vinyl tubing over to the top of your gasometer. The quicker the heat is spead through the highly heat conductive copper the less heat in the gas. Also the surface area of the copper in contact to the air around will extract more heat to the air more as the surface area increases. It is not necessary in my analysis to run the tubing all the way over to the gasometer.
Also to help draw the heat out of the gas in the copper line a dryer type device could be used to let the water go by and catch the heat - suggest some shavings like steel wool but stainless steel -- too bad copper would oxidize and not act as a heat transfer media to the casing of the copper enclosure of the dryer.
The combo of the copper tubing and a 'dryer' which really does not absorb water but heat, passing heat to the air to be absorbed probably will make the gas cool towards the juncture of copper and vinyl tubings.
