Excellent and thanks for sharing, I' writing from Spain, my father who was born in 1913, was a cars mechanic, and he explained me that after the spanish civil war (1936 - 1939), Spain's lack of petrol moved many mechanics like my father, to self build wood or coal gasifiers, really very similar to yours, (Spanish called "gasógenos"), they were supported at the back of the car with iron rods welded to the chassis, and he runned thousands of miles (several times across the whole Spain) with different cars, Peugeot, Citröen, Fiat, Ford, and a very rare 1920 Maxwell, with which I learn to drive when I was a child.
I can't even imagine what they would look like. Is there any way you could email me even a very rough sketch of how that would be set up? Thank you for whatever you can send. ChangingMatrix@gmail.com

Wood is renewable only if you can grow back all the trees. And it is actually extremely difficult to grow a forest. If it were easy, then places like Arizona would have grown back its forests. Archaeologists have solid evidence that Arizona was once a big forest, just like Amazon. And Amazon is NOT an old forest. Instead, it was pretty new and only started to regrow after all humans were wiped out for some unknown reasons.

Using soft copper tubing coiled around the barrel to a large hot water tank will put the waste heat to good use. Running the generator at optimum rpm to charge a battery bank will keep the generator from wasting a lot of wood gas when not under load.
I have to comment on this build and video! This is amazing and truly educational! You explained things well and my favorite part is talking about the FREE manual you can get and read to learn how to build your own. This is an answer to problems we have and a way for the regular person to solve them with wood which is around us all. Thank you for making this video!!
Most of Outback Australia up to 1945 generated electricity from huge suction gas engines, they used wood gas to run them through a retort and using massive horizontally opposed engines that created the suction through the wood charcoal gasifier. After WWar II converted to diesel.
violeman I agree. This is one of the best homemade Gasifiers I've seen. Very nice looking, easy to see and well explained how it was made and such a great demonstration from startup to running a saw off of it! Thanks so much!
The balance of stokiometry (air fuel ratio) happens at both the front fuel end and again at the engine generator. I've built larger versions of these (10MW)...partially choke the inlet feeder with a double gate valve assembly and you can improve the efficiency. The reason the barrel is getting hot is because there is too much combustion taking place at the feed end. It's a delicate balance keeping both variable components in perfect balance. You need J-U-S-T enough gasification to generate combustible pyrolysis gases (mainly methane C4, C5, C6 hydrocarbons)to feed the engine. Too much air flow and you are unnecessarily combusting wood pellets and unnecessary heat the barrel. BTW when you move into the C8 hydrocarbon range you are in the octane range or gasoline range. PYROLYSIS can generate biodiesel C16-C20 range some of which is mixed with the water in that separator glass. Great work though... hats off!
@@invent5540 great analysis John. You seem to know your stuff. Got any videos or materials on what you just explained? Thanks in anticipation of your response
@@josephjames7658 Hi Joseph... I worked with a retired elderly man in the early 80's who studied at the Zurich Poytechnic Institute under Einstein before WWII... he often spoke about how the Polish underground ran their vehicles using Pyrolysis wood gasification in WWII. Before he passed away we built two reactors. The second was 10MW! A monster... Pyrolysis... true PYROLYSIS is absolutely without the presence of Oxygen... gasification is poor mans pyrolysis! But still good... true pyrolysis generates 100% activated carbon. Gasification damages the carbon matrix with oils that fill the Carbon voids. Lookup Absorption vs. Adsorbtion as it relates to Activated Carbon. Typically we use freaon mass variations to measure the quality of the Activated Carbon. This technology can "believe it or not" SAVE this planet... since it sequesters Carbon. I could go on and on btw.
Best I've seen. Keep in mind it produces less power on smoke gas than with petrol. So if you plan to run stuff get the biggest generator you can afford. Run the smoke gas through a large radiator, like off an old bulldozer, early in the process and attach the goop trap under it. That will take a ton of heat off the gas. And if you can mist water on that radiator at the same time you will substantially cool it further.
Well done. not only for the finished product but for the video as well. You know what you wanted to say and you said it. Saved me a lot of screaming at a LCD screen telling people to get on with it. Your description of the way it worked was nice and simple and while I have been toying with the idea of building one of these for a while have been put off, a bit, by the seemingly involved explanations. Like the use of materials as well. Can get most of that from the dump recycle shop. Thanks.
Good job! Good explanation! Think about a gasifier that would provide heat and hot water for your house along with running a whole house generator and become totally self sufficient!
If you can buy or rent a few acres of medium-wet land, then grow biomass varieties of willow, you'll be more than self sufficient in energy production.
kostman23 Hey, let’s continue using fossil fuels and cause irreversible damage to the atmosphere so we can make ourselves extinct! You do realize that this stuff has 1/10 of the carbon emissions.... and that TREES REGROW...
Nice work & video. if you get a wide range O2 sensor on the exhaust of the gen, you can dial the mixture a tad rich and the gen engine will last just as long as reg fuel. gas(fuel) helps cool the piston, so your gonna want to stay a bit rich. you may be able to run some of the exhaust back into the gasifier - lacking O2 it might keep it from back burning...keeping it cool. I like your setup
Great video! You motivated me to build this. It's too bad you need to have bars on your house. I used to own a security alarm company and always heard about people dying when their house caught fire. I sold alarms in a ton of bad neighborhoods. Some areas were so bad that my customers insisted on walking me to my car. lol
I find that cooler wood gas works more consistently with very few fuel/air adjustments and a very steady engine operation. I simply used old water pipes with fins from old baseboard heaters running back and forth in an 8 foot water tank, but any design for the water tank will work if shaded from the sun. Thanks for the video.
Most definitely, condensing the gas output will concentrate it further; likewise, recirculating the exhaust gas after sustainable combustion should further break it down and give a secondary burn to the mix, using up the remaining condensation and unburned fuel. But where is optimal and safe? Into the spin down, ammo can, pre-cooling, or post-cooling?
Love the gasifier stuff! In Sweden we had cars that run on it when the gas/petrol was at an all time high. Next version would be some sort of TEC that took some of the heat generated and convert it (thru a custom charger) electricity to charge a battery. That battery would then power the fan and maybe even start the fire. The generator would be a custom one that was built for gas for maximum throughput. So in essence put branches in press button wait for power... that would be awesome... and then make it small an compact (but still use off the shelves parts for cheap repair/build). And a solenoid to do some shaking :-)
My hat’s off to you man! So inspirational and totally Rad. Beautiful build and incredibly resourceful- obviously you’re an engineer, whether professionally or just naturally-born. You’re awesome and your modesty shines through
Excellent! I plan on building one of these to power a small wood chipping machine, which I use to process my willow plantation waste. Some of the (dried) woodchips can be used to fuel the gasifier, so creating a circular system as done by the late Jean Pain decades ago.
Looks like a very neat straightforward system. Sadly if you can smell camp fire at the engine exhaust it means you are still getting creosote/tar in the gasses which will inevitably gunk up all the engine parts, this is the reason wood gas trucks weren't used for very long. Maybe multiple tar catchers can be put in place to try and minimize what manages to escape.
Run thru an oil-bath air cleaner should work unless the tar/creosote/asphalts (heavy oil products) are vaporized to the point of bypassing the oil in the air cleaner...🤔🤷🏻♂️🤔🕵🏻♂️??
This is the coolest thing I've seen! Definitely going to build one of my own. I plan on building a microhome that I can get off the grid with and this will definitely come in handy to charge my lithium-ion battery pack on days when solar is not an option. I will also run some copper tubing around the combustion chamber to not only cool it but to heat water for a hot shower! Thank You So Much!!!
That is nice. I have seen a show on discovery where some people use same type of gasfier and run their pick up trucks on the gas generated by same type of gasifier. They only difference was that they used wood logs. It can be done. In some countries they burn trash and run gasifiers to make electricity, but the pollution issue has to be considered.
Zain Abidin the cyclone unit and the carbon scrubber are setup to collect the dirtier compounds. However, if it is just wood, the product would primarily be methane, as seen by the invisible flame. The input of trash would result in noxious (NOx) compounds and harmful sulfur compounds and other acids... naturally you want to avoid that unless you are using a multimillion dollar plasma gasification system
Just downloaded the plans and this video, I am definitely building one of these in the future. One idea though. If you get a generator with electric start, you could start the gassifier with the gen battery and then start it off the battery and then it would be recharged for the next use.
The fan in this design uses 25W at most, which means that 3 18650 cells would be able to power it without any issue. You don't need to pay extra for a generator with a fancy electric starter, a Powerbank that does 12V will easily do it.
@@nottheengineer4957 Well electric start would probably make it easier if you didnt have the fuel valves set, idk just seems like less to worry about cause it maintains itself. It would probably be a used generator off facebook anyway so I dont think price would factor in much.
@@Jasonrotfl Im with you. Ill buy the fancy electric start generator while I can. Not like you can get one after the Boogaloo or full chinese invasion hits, or some other disaster. Might as well make your life just a little easier.
@@exterminater267 did just that. three generators on hand - one dedicated to gasification just in case. Plus the 4.6 kilowatt in solar panels...you know what's going on these days...not sure about "tomorrow"...
Perhaps the cleanest and most professionally built gasifier I have seen to date. Kudos! Btw, instead of a rheostat, you should use a pwm motor controller for a dc brushed motor. They also make controllers for brushless, but they are a bit more expensive. But great build! 🙂
Love that you made it work with a oil drum but that looks to thin as the part your using it for I love that you have a open top also to help disperse moisture at combustion side
Damn this is awesome!! In 2021the hardest part of building this is finding a RadioShack for the potentiometer!! Lol. All jokes aside this is super cool man!! Thanks for sharing. Kudos to you sir.
Since the demise of RadioShack and Fry's Electronics, there are quite a few places online where you can get parts. DigiKey, Mouser, and Jameco comes to mind. You might also find luck with surplus distributors such as All Electronics.
This is impressive! It'd take some doing and someone with the knowledge, but it'd be really awesome to rig up a microcontroller and stepper motors and such to make the whole thing self-regulating. Automatic adjustment of the air/fuel ratio into the generator, blower speed control, grate shaker, etc. Anyway, this is a really good setup, and quite an achievement! One other thing: how well does it keep up when the generator is loaded? A saw draws way more power when it's cutting something.
Amazing Job!! I need to make one of these because my utility/ power company is unreliable and the power goes out all of the time. Thanks for the great ideas.
It's so interesting , I heard about this idea years ago but I've never seen one ,apparently back in the 30s they used to run some big trucks on this system ,it's a brilliant video so grateful for your video many thanks ,!

Very impressive build. The only thing I would have done differently would be to get rid of the rubber couplers (your weak link), add a cooling system of some form and possibly a car blower motor instead of a inflation motor (they aren't designed for continuous duty.) You could also use a blower motor switch and resistor block from an old car to control your speed.
It doesn't need a constant duty blower motor, it only needs to run a few minutes to start it up - about the same duty as blowing up a large air mattress.
You can use perforated metal with 1/16" holes as a backfire arrestor it works very well and wont fail. I do lots of testing on different forms of fuel vapors and this method has worked for everything I have tested. The air to fuel mixture will be allot easier to dial in if you use a gate valve instead of a ball valve. The gate valves will fine tune the ATF allot better then a ball valve. Hope this helps.
Pretty slick! I'm in the process of learning all the maths involved in a gasification. I plan on adding some automobile sensors for gas mixing automation.
I realize my comment is very late. Very impressive! I'm thinking, based on the invisible flame, you are burning mostly hydrogen. You've filtered out most of the carbon. How green are you! Nice work young man!!
Super nice build man. I’m behind the curve but I plan to build one large enough to power my house in outages here due to severe weather. Very exciting stuff! I’m like a kid in a candy store with this stuff...and the plastics potential with gasification output...holy cow, diesel and gas from plastic...I mean come on
How are you getting fuel from plastics? In a gasifier? Sorry but I'm also new to this and trying to learn as much as possible, using plastics for fuel sounds amazing.
You or someone needs to start selling these! Full KIt could include: 1. one gasifier with large woodchip loader and pilot light on a timer. 2 one 2000-4000w gas generator 3. Two large battery generator 4. maybe some solar panels (in case you run out of wood chips lol) have the gasifier charge the 2000-4000w gas generator, which then keeps one or both of the 2 battery generators/banks charged at all times. Endless energy.
I've looked up FEMA plans for gasifiers and I couldn't find plans that looked like yours. I think your a really intelligent fabricator welder and got the ideas off of one of them and made up your own design which is very talented. I likewise have welded and fabricated in my past. I have a little 110 V welder and have enough grinders, etc. to do something like this. Kudos to you and thanks for sharing this beauty.
nice and clean build. you can use a simple PWM circuit as control to your airpump instead of a direct pot. By that, you can use a low wattage pot without unwanted heating.
Big thanks to you, this is by far the best vid on these things I have seen .a great visual as well as verbal explanation. It can be hard to get one's head around how and why something works you have given me the itch to build one myself now when the summer gets hear so I'll be off collecting parts till then :) great job ...
very nive build. have you considered a PWM controller instead of your rheostat? The rheostat will simply waste electrical power so the motor runs slower. The PWM will be more effective in this area. also a 12/24V and 3A pwm is onlz 2buck on ebay vs 8 or 9 for a rheostat. But as for the actual design. i've read and studied the FEMA plans and the comments I've been gathering online is that this vanilla design does not filter tar well enough to run agenerator for long. So I ould like to hear your opinion about that. and also when I build one, how can i know or measure that the tar is filtered out enough? thanks a lot.
but he wants it to run slower that was the point. a PWM controller wont let him reduce the power to the blower fan to reduce the blowing force like the rheostat will. the blower fan needs to run slower at first to ignite the fire then later run faster. PWM cant do that.
i finally understood how this works, without reading any book but by watching the same video for 173 times :) now i can make a giagantic gasifier out of my grandfathers pizza giant oven
Out of everybody on the internet that I have seen Bill to gasifier yours is by far the best looking the best working I've totally impressed with the way you built yours call all the other ones they look like a bunch of junk welded together and I see tar build up on them on the motors how much car builds up have you gotten on your generator I'm going to imagine that yours is very efficient and you catch most of your car in your filtering system the animal box was an excellent idea keep up the good work
That’s really brilliant I run a wood yard and use petrol powered hydraulic power packs for my fire wood splitters one of these would work great for me. Thanks for sharing. I am of to my workshop. lol. I run a gasification system for my kiln that I use to dry firewood with a massive chimney . It is set up between to semi box trailers that I fill with wet wood. You have got me thinking now.
Great job! I have some questions about practicality: - In a situation where petrol isn't available, it seems unlikely that wood pellets would be available. Can you run this thing on logs, branches, twigs, kindling etc? - How long can you run this on a single "tank" of wood? - If you load the generator, does it stall? - What regular and irregular maintenance is required? For example, how often do you have to replace the wood shavings in the filter? How often do you need to clear the ash? How often do you need to empty the jam jar? Are there other jobs necessary to keep it running over years? Do any of those jobs involve partial or full disassembly? Its amazing to see a petrol engine run on wood, now I want to know what its like to actually use this cool tech.
Ever heard of a hopper bottom bin? Great for farmers putting there grain into, a lot easier to get the grain out that way compared to a flat bottom bin.
Hi JR, Thank you for your Great Video. It really helped me to Understand how Wood Gasifiers work. I am building a Wood Gasifier now. I have a couple of questions. 1) What kind of Green Paint did you use? 2) Where exactly did you weld the Starter Tube onto the Fire Tube?,( How far from the bottom?) 3) What is the distance from the Bottom of the Fire Tube to the Basket? 4) Other than the Fire Tube, what diameter are the other pipes that you are using, like the pipe to the filters? I very much appreciate your help. Thanks, Mike

Haven’t read all comments yet but see with a little more construction heating your water with it and improving performance by cooling the gas in the process. Thanks though this is super.
Looks like you do nice work my man. As a builder I recognize thoughtfully done good work when I see it. I admit I don't have much knowledge regarding wood/gas stoves but I do want to build one! I'm a 'from scratch' builder and I absolutely love building with steel and I only use what most folks call garbage: scrap metal, all of it is either from our local garbage dump, our local scrapyards and I regularly check the back alleys for automotive repair shop scrap metals. How much do you folks pay for a bag of wood pellets? Here in Alberta we pay $7.00 dollars for a 40 pound bag.
Bars on the windows...alarm placard in front "lawn". Honestly, I think lack of power is going to be the least of your worries if power goes out for a hot minute.
Air flow meters might help you with the precision your looking for. What’s the full run time of one load of pellets? And can you store the gas refined?

Yea this is probably the best one I’ve seen ever.
Very well done. Your generator was sitting there and running without a single miss. Finally a gas unit that actually runs at a sustained rate.
You can find plans from popular mechanics I think from ww2 where they have designs that were intended to run a car on. Federal government, probably fema, has published plans also. I didn't hear where he got his design or if it's all his I skipped through a bit
@@MF11283 shame on you.
Using soft copper tubing coiled around the barrel to a large hot water tank will put the waste heat to good use. Running the generator at optimum rpm to charge a battery bank will keep the generator from wasting a lot of wood gas when not under load.
I have to comment on this build and video! This is amazing and truly educational! You explained things well and my favorite part is talking about the FREE manual you can get and read to learn how to build your own. This is an answer to problems we have and a way for the regular person to solve them with wood which is around us all. Thank you for making this video!!
Most of Outback Australia up to 1945 generated electricity from huge suction gas engines, they used wood gas to run them through a retort and using massive horizontally opposed engines that created the suction through the wood charcoal gasifier. After WWar II converted to diesel.
Awesome !!!
This has got to be,
One of the best Homemade Gasifiers I have ever seen so far !!!!
Thanks 4 Sharing Bud!!!
violeman I agree. This is one of the best homemade Gasifiers I've seen. Very nice looking, easy to see and well explained how it was made and such a great demonstration from startup to running a saw off of it!
Thanks so much!
violeman Yep, I second that.
The balance of stokiometry (air fuel ratio) happens at both the front fuel end and again at the engine generator. I've built larger versions of these (10MW)...partially choke the inlet feeder with a double gate valve assembly and you can improve the efficiency. The reason the barrel is getting hot is because there is too much combustion taking place at the feed end. It's a delicate balance keeping both variable components in perfect balance.
You need J-U-S-T enough gasification to generate combustible pyrolysis gases (mainly methane C4, C5, C6 hydrocarbons)to feed the engine. Too much air flow and you are unnecessarily combusting wood pellets and unnecessary heat the barrel. BTW when you move into the C8 hydrocarbon range you are in the octane range or gasoline range. PYROLYSIS can generate biodiesel C16-C20 range some of which is mixed with the water in that separator glass.
Great work though... hats off!
@@invent5540 great analysis John. You seem to know your stuff. Got any videos or materials on what you just explained? Thanks in anticipation of your response
@@josephjames7658
Hi Joseph... I worked with a retired elderly man in the early 80's who studied at the Zurich Poytechnic Institute under Einstein before WWII... he often spoke about how the Polish underground ran their vehicles using Pyrolysis wood gasification in WWII. Before he passed away we built two reactors. The second was 10MW! A monster... Pyrolysis... true PYROLYSIS is absolutely without the presence of Oxygen... gasification is poor mans pyrolysis! But still good... true pyrolysis generates 100% activated carbon. Gasification damages the carbon matrix with oils that fill the Carbon voids. Lookup Absorption vs. Adsorbtion as it relates to Activated Carbon. Typically we use freaon mass variations to measure the quality of the Activated Carbon. This technology can "believe it or not" SAVE this planet... since it sequesters Carbon. I could go on and on btw.
holy cow, this is an eye opener, and the crazy thing is your vide is from almost 7 years ago!!
Considering that during/after WW2 many vehycles in Europe ran on this, you can't say it's that much of a breakthrough. But he did a good job.
@@trezapoioiuy yeah, i learned that after scrolling thru the comments, but only after writing the above down
You want you brain to boil, check out the guy that drives a 90's Dodge pickup with wood.

Best I've seen. Keep in mind it produces less power on smoke gas than with petrol. So if you plan to run stuff get the biggest generator you can afford. Run the smoke gas through a large radiator, like off an old bulldozer, early in the process and attach the goop trap under it. That will take a ton of heat off the gas. And if you can mist water on that radiator at the same time you will substantially cool it further.
What a smart young man. These would work great in a Off Grid Environment.
Awesome... I'm going off grid soon and this will be a fun little project to top up my batteries once in a while on cloudy days.
Hello Jr. Both your machine and the video are very well thought through and executed. I admire your sense of craftsmanship. Thank you very much!!!
This is an excellent application example. Ideal for charging a bank of batteries in the winter when the sky is overcast etc...Nice neat job too.
Well done. not only for the finished product but for the video as well. You know what you wanted to say and you said it. Saved me a lot of screaming at a LCD screen telling people to get on with it. Your description of the way it worked was nice and simple and while I have been toying with the idea of building one of these for a while have been put off, a bit, by the seemingly involved explanations. Like the use of materials as well. Can get most of that from the dump recycle shop. Thanks.
The best demo I've seen connecting up the geni. No one shows the application usually, just the build, so thanks again
Good job! Good explanation! Think about a gasifier that would provide heat and hot water for your house along with running a whole house generator and become totally self sufficient!
And think about no one tree left standing lol
If you can buy or rent a few acres of medium-wet land, then grow biomass varieties of willow, you'll be more than self sufficient in energy production.
This as a concept needs to be invested in more nowadays. This is genuinely amazing.
Yeah, so we can cut down all our trees in the next 10 years. Go green!!!
kostman23 Hey, let’s continue using fossil fuels and cause irreversible damage to the atmosphere so we can make ourselves extinct! You do realize that this stuff has 1/10 of the carbon emissions.... and that TREES REGROW...
It is being used widely but in bigger scale ~200kw or bigger power generators that burn like 100kg of biomass every hour.
I remember seeing a picture of this exact setup on a SHTF forum years ago and now I finally get to see it in action. Thanks for posting the video man.
I dream of one day going off grid lifestyle. That is why I am watching this.
Outstanding! Compact unit, ur hard work will pay off. They should be teaching and building these in high schools.
The best explanation of gasifier on UA-cam
You got that right 👍
@@charlieharrington1144 yes
Nice work & video. if you get a wide range O2 sensor on the exhaust of the gen, you can dial the mixture a tad rich and the gen engine will last just as long as reg fuel. gas(fuel) helps cool the piston, so your gonna want to stay a bit rich. you may be able to run some of the exhaust back into the gasifier - lacking O2 it might keep it from back burning...keeping it cool. I like your setup
Great video! You motivated me to build this. It's too bad you need to have bars on your house. I used to own a security alarm company and always heard about people dying when their house caught fire. I sold alarms in a ton of bad neighborhoods. Some areas were so bad that my customers insisted on walking me to my car. lol
I find that cooler wood gas works more consistently with very few fuel/air adjustments and a very steady engine operation. I simply used old water pipes with fins from old baseboard heaters running back and forth in an 8 foot water tank, but any design for the water tank will work if shaded from the sun.
Thanks for the video.
Most definitely, condensing the gas output will concentrate it further; likewise, recirculating the exhaust gas after sustainable combustion should further break it down and give a secondary burn to the mix, using up the remaining condensation and unburned fuel. But where is optimal and safe? Into the spin down, ammo can, pre-cooling, or post-cooling?
That's the purest form of electricity lv ever seen! Excellent!
Love the gasifier stuff! In Sweden we had cars that run on it when the gas/petrol was at an all time high.
Next version would be some sort of TEC that took some of the heat generated and convert it (thru a custom charger) electricity to charge a battery. That battery would then power the fan and maybe even start the fire. The generator would be a custom one that was built for gas for maximum throughput.
So in essence put branches in press button wait for power... that would be awesome... and then make it small an compact (but still use off the shelves parts for cheap repair/build).
And a solenoid to do some shaking :-)
My hat’s off to you man! So inspirational and totally Rad. Beautiful build and incredibly resourceful- obviously you’re an engineer, whether professionally or just naturally-born. You’re awesome and your modesty shines through
Excellent. You have it. If there was an engineering version of American Idol, you be in the finals.
Omg what an idea.... Why haven't they think about that yet
hahahaha and there should be,,id much rather watch that
You do know that this tech was used on bicycles that ran on wood gas right?
Japan has a show like that. It's called supreme skills.
Their is one
This thing is so simple it’s scary. Great work in presenting an impossible concept.
Excellent! I plan on building one of these to power a small wood chipping machine, which I use to process my willow plantation waste. Some of the (dried) woodchips can be used to fuel the gasifier, so creating a circular system as done by the late Jean Pain decades ago.
How'd it go
My Grandad ran his car, (a Hudson), on a gasifier during WW2 when petrol was very difficult to get.
only just found this video. terrific unit and does the job. should be more of this going on and more people looking into it. well done
Looks like a very neat straightforward system.
Sadly if you can smell camp fire at the engine exhaust it means you are still getting creosote/tar in the gasses which will inevitably gunk up all the engine parts, this is the reason wood gas trucks weren't used for very long. Maybe multiple tar catchers can be put in place to try and minimize what manages to escape.
Run thru an oil-bath air cleaner should work unless the tar/creosote/asphalts (heavy oil products) are vaporized to the point of bypassing the oil in the air cleaner...🤔🤷🏻♂️🤔🕵🏻♂️??
@@westtexastll1978 just need to cool the air enough first right? Oil bath cleansers seem really cool and straight forward.
This is the coolest thing I've seen! Definitely going to build one of my own. I plan on building a microhome that I can get off the grid with and this will definitely come in handy to charge my lithium-ion battery pack on days when solar is not an option. I will also run some copper tubing around the combustion chamber to not only cool it but to heat water for a hot shower! Thank You So Much!!!
that is about the cleanest version ive seen. excellent work.
That is nice. I have seen a show on discovery where some people use same type of gasfier and run their pick up trucks on the gas generated by same type of gasifier. They only difference was that they used wood logs. It can be done. In some countries they burn trash and run gasifiers to make electricity, but the pollution issue has to be considered.
Zain Abidin the cyclone unit and the carbon scrubber are setup to collect the dirtier compounds. However, if it is just wood, the product would primarily be methane, as seen by the invisible flame. The input of trash would result in noxious (NOx) compounds and harmful sulfur compounds and other acids... naturally you want to avoid that unless you are using a multimillion dollar plasma gasification system
I remember that show! Do you remember the name??? I thought about that same show as I was watching this but I failed to remember.
Just downloaded the plans and this video, I am definitely building one of these in the future.
One idea though. If you get a generator with electric start, you could start the gassifier with the gen battery and then start it off the battery and then it would be recharged for the next use.
The fan in this design uses 25W at most, which means that 3 18650 cells would be able to power it without any issue. You don't need to pay extra for a generator with a fancy electric starter, a Powerbank that does 12V will easily do it.
@@nottheengineer4957 Well electric start would probably make it easier if you didnt have the fuel valves set, idk just seems like less to worry about cause it maintains itself. It would probably be a used generator off facebook anyway so I dont think price would factor in much.
@@Jasonrotfl Im with you. Ill buy the fancy electric start generator while I can. Not like you can get one after the Boogaloo or full chinese invasion hits, or some other disaster. Might as well make your life just a little easier.
@@exterminater267 did just that. three generators on hand - one dedicated to gasification just in case. Plus the 4.6 kilowatt in solar panels...you know what's going on these days...not sure about "tomorrow"...
Perhaps the cleanest and most professionally built gasifier I have seen to date. Kudos! Btw, instead of a rheostat, you should use a pwm motor controller for a dc brushed motor. They also make controllers for brushless, but they are a bit more expensive. But great build! 🙂
How much rpm motor for blower is required for operation
@@raismohammadmuqeemmubin3379 depends on the gasifier, size and shape of the rotors
extra kudos for the recycled (upcycled) parts. Very inspiring video.
Love that you made it work with a oil drum but that looks to thin as the part your using it for I love that you have a open top also to help disperse moisture at combustion side
Damn this is awesome!! In 2021the hardest part of building this is finding a RadioShack for the potentiometer!! Lol. All jokes aside this is super cool man!! Thanks for sharing. Kudos to you sir.
Since the demise of RadioShack and Fry's Electronics, there are quite a few places online where you can get parts. DigiKey, Mouser, and Jameco comes to mind. You might also find luck with surplus distributors such as All Electronics.
I didn't think Radio Shack still existed but man in the day I spent some money in there
I need one of these for my Farm, done a nice job painting it and fixing it up. seen several that look like old moon shine steals
This is impressive! It'd take some doing and someone with the knowledge, but it'd be really awesome to rig up a microcontroller and stepper motors and such to make the whole thing self-regulating. Automatic adjustment of the air/fuel ratio into the generator, blower speed control, grate shaker, etc. Anyway, this is a really good setup, and quite an achievement! One other thing: how well does it keep up when the generator is loaded? A saw draws way more power when it's cutting something.
I have hundreds of achers of wood I can use, could you help me make a blueprint
Amazing Job!! I need to make one of these because my utility/ power company is unreliable and the power goes out all of the time. Thanks for the great ideas.
It's so interesting , I heard about this idea years ago but I've never seen one ,apparently back in the 30s they used to run some big trucks on this system ,it's a brilliant video so grateful for your video many thanks ,!
I keep coming back to this demo, it is the best implementation I have been able to find :-)
SUPER clean design! Awesome job! I'm just now learning of this technology. I'm hoping I can build one myself! Thanks for sharing!

I watched a WW2 Documentary years ago that showed one of these on a German tank. Now, I understand what it was ! Great Video !
This video is probably the most informative I have seen on a gasifier. Thank you.
Very impressive build. The only thing I would have done differently would be to get rid of the rubber couplers (your weak link), add a cooling system of some form and possibly a car blower motor instead of a inflation motor (they aren't designed for continuous duty.) You could also use a blower motor switch and resistor block from an old car to control your speed.
It doesn't need a constant duty blower motor, it only needs to run a few minutes to start it up - about the same duty as blowing up a large air mattress.
@@WestCoastWheelman Got it! Thanks for correcting me!
love how its uniform, looks pretty PRO
You can use perforated metal with 1/16" holes as a backfire arrestor it works very well and wont fail. I do lots of testing on different forms of fuel vapors and this method has worked for everything I have tested.
The air to fuel mixture will be allot easier to dial in if you use a gate valve instead of a ball valve. The gate valves will fine tune the ATF allot better then a ball valve.
Hope this helps.
Globe valve would be the best. Since you're not supposed to adjust flow on a gate valve.
That would work fine too. You don't have a high pressure behind the gate valve so it will be just fine.
Pretty slick! I'm in the process of learning all the maths involved in a gasification. I plan on adding some automobile sensors for gas mixing automation.
Your video has stood the test of time, it is still the best gasifier build and explanation on youtube....Thank you!
I realize my comment is very late. Very impressive! I'm thinking, based on the invisible flame, you are burning mostly hydrogen. You've filtered out most of the carbon. How green are you! Nice work young man!!
Super nice build man. I’m behind the curve but I plan to build one large enough to power my house in outages here due to severe weather. Very exciting stuff! I’m like a kid in a candy store with this stuff...and the plastics potential with gasification output...holy cow, diesel and gas from plastic...I mean come on
How are you getting fuel from plastics? In a gasifier? Sorry but I'm also new to this and trying to learn as much as possible, using plastics for fuel sounds amazing.
You or someone needs to start selling these! Full KIt could include:
1. one gasifier with large woodchip loader and pilot light on a timer.
2 one 2000-4000w gas generator
3. Two large battery generator
4. maybe some solar panels (in case you run out of wood chips lol)
have the gasifier charge the 2000-4000w gas generator, which then keeps one or both of the 2 battery generators/banks charged at all times. Endless energy.
Endless wood chipping.
I've looked up FEMA plans for gasifiers and I couldn't find plans that looked like yours. I think your a really intelligent fabricator welder and got the ideas off of one of them and made up your own design which is very talented. I likewise have welded and fabricated in my past. I have a little 110 V welder and have enough grinders, etc. to do something like this. Kudos to you and thanks for sharing this beauty.
nice and clean build. you can use a simple PWM circuit as control to your airpump instead of a direct pot. By that, you can use a low wattage pot without unwanted heating.
Big thanks to you, this is by far the best vid on these things I have seen .a great visual as well as verbal explanation. It can be hard to get one's head around how and why something works you have given me the itch to build one myself now when the summer gets hear so I'll be off collecting parts till then :) great job ...
very nive build.
have you considered a PWM controller instead of your rheostat? The rheostat will simply waste electrical power so the motor runs slower. The PWM will be more effective
in this area. also a 12/24V and 3A pwm is onlz 2buck on ebay vs 8 or 9 for a rheostat.
But as for the actual design. i've read and studied the FEMA plans and the comments
I've been gathering online is that this vanilla design does not filter tar well enough to
run agenerator for long.
So I ould like to hear your opinion about that. and also when I build one, how can i know or measure that the tar is filtered out enough?
thanks a lot.
but he wants it to run slower that was the point. a PWM controller wont let him reduce the power to the blower fan to reduce the blowing force like the rheostat will. the blower fan needs to run slower at first to ignite the fire then later run faster. PWM cant do that.
i finally understood how this works, without reading any book but by watching the same video for 173 times :)
now i can make a giagantic gasifier out of my grandfathers pizza giant oven
relatable comment lol
Out of everybody on the internet that I have seen Bill to gasifier yours is by far the best looking the best working I've totally impressed with the way you built yours call all the other ones they look like a bunch of junk welded together and I see tar build up on them on the motors how much car builds up have you gotten on your generator I'm going to imagine that yours is very efficient and you catch most of your car in your filtering system the animal box was an excellent idea keep up the good work
That’s really brilliant I run a wood yard and use petrol powered hydraulic power packs for my fire wood splitters one of these would work great for me. Thanks for sharing. I am of to my workshop. lol. I run a gasification system for my kiln that I use to dry firewood with a massive chimney . It is set up between to semi box trailers that I fill with wet wood. You have got me thinking now.
Great job! I have some questions about practicality:
- In a situation where petrol isn't available, it seems unlikely that wood pellets would be available. Can you run this thing on logs, branches, twigs, kindling etc?
- How long can you run this on a single "tank" of wood?
- If you load the generator, does it stall?
- What regular and irregular maintenance is required? For example, how often do you have to replace the wood shavings in the filter? How often do you need to clear the ash? How often do you need to empty the jam jar? Are there other jobs necessary to keep it running over years? Do any of those jobs involve partial or full disassembly?
Its amazing to see a petrol engine run on wood, now I want to know what its like to actually use this cool tech.
you need a hopper on top to hold more wood pellets
+jonathon watterson It isn't minecraft.
+ttyk not minecraft real life xD
+jonathon watterson That wouldn't be hard at all, just bend some aluminum and pressure fit it.
+ttyk Hoppers exist in real life too you know.
Ever heard of a hopper bottom bin? Great for farmers putting there grain into, a lot easier to get the grain out that way compared to a flat bottom bin.
Hi JR, Thank you for your Great Video. It really helped me to Understand how Wood Gasifiers work. I am building a Wood Gasifier now. I have a couple of questions. 1) What kind of Green Paint did you use? 2) Where exactly did you weld the Starter Tube onto the Fire Tube?,( How far from the bottom?) 3) What is the distance from the Bottom of the Fire Tube to the Basket? 4) Other than the Fire Tube, what diameter are the other pipes that you are using, like the pipe to the filters? I very much appreciate your help. Thanks, Mike
Very cool! Do you have any feedback on how much buildup you get in the engine? I’m curious how long that will run without gumming everything up.
Very well done..I’ve seen so many that come close to working but don’t, yours actually works! Congratulations!
Amazing how everyone shares their life story. Great build and thank you for sharing they want to talk about clean energy well this is it
You sir, are an awesome thinker. Good use of stuff laying around and sourced.
Awesome job! Version 2.0 needs a water cooled / water heater system and a variac instead of a reostat.
Variacs don't work on DC.
UA-cam recommended this to me 6 years later. (Even if I've watched it before.)
I seen one of those up in the mountains and it had magic powers when you drink the juice we would sing songs around the fire wearing nothing but our Willy warmers .. oh the good old days 😊
Haven’t read all comments yet but see with a little more construction heating your water with it and improving performance by cooling the gas in the process. Thanks though this is super.
Great idea !
Could you place copper tubing as a coil inside barrel and heat water for showing etc. While cooling vapor?
Great question . Liquid bathing the coils could help too .
Of course.
Don't cool it in the barrel. Cool in the next stage. It will collapse the vapor and create a vacuum.
@@scottatmursedotnet you got it, skip the wood chip mat, make a coil in the ammo can
Looks like you do nice work my man. As a builder I recognize thoughtfully done good work when I see it. I admit I don't have much knowledge regarding wood/gas stoves but I do want to build one! I'm a 'from scratch' builder and I absolutely love building with steel and I only use what most folks call garbage: scrap metal, all of it is either from our local garbage dump, our local scrapyards and I regularly check the back alleys for automotive repair shop scrap metals.
How much do you folks pay for a bag of wood pellets? Here in Alberta we pay $7.00 dollars for a 40 pound bag.
Bars on the windows...alarm placard in front "lawn". Honestly, I think lack of power is going to be the least of your worries if power goes out for a hot minute.
$4 a gallon gas after one year in the oval office. I'm gonna make a gasifier. Thanks for the video of your excellent build.
This is the best plan and explanation I've seen so far.
Wow...nice job! Good explanation and execution. Thank you.
Thank you, that was really interesting - a very concise explanation and well presented video. Good paint job too, looks almost factory-made!
Air flow meters might help you with the precision your looking for. What’s the full run time of one load of pellets? And can you store the gas refined?
Nice to see people sharing what has the potential to actually help and not take from
Thanks JR
This is brilliant! All you need to do now is build a case to dampen the noise of the generator.
