A great little Gasifier from The folks at Foutch industries in Tennessee.
LEAF stand for low emission alternative fuel.
The production units will be green.

I find it ironic how people like to pose the chicken or the egg question about gasifiers and their operation. Most people that are going to go through the trouble of building a gasifier are going to consider drafting one in a power outage. The point of a gasifier is to be able to harvest and store fuel for energy without gasoline. I live in the mountains and with a bow saw and a 10 lb maul I could keep my genny running for a while. Or even better I could save my gasoline for my chain saw and use syngas to run my log splitter and generator. Either way the person who builds and operates a gasifier is going to be better off than the guy who thinks banks and gas stations will be open when there is an extended power outage or disaster.
FYI, the egg came first, if that helps :)
Wrong. The blue green algae came first.
Nicholas Pope Context, in-relation to the statement...learn some.
Do you even know what the context of the egg chicken is in reference to you troll. Doubt it.
Nicholas Pope It's relating to how the universe began. Evolutionists use it as a mock-up for evolution. I am sure it has other applications as time has passed since it is a cause and effect statement with no beginning or end.
Let me get this right, because I mock your inability to follow my remark, for what it was put forth in, I am the troll ?
Makes you seem sort of like a dumbass
Nice looking little compact gasifier, I built one last December then I built a Imbert design that burns really clean. I'm using it with a small generator and the gasifier runs on yard waste. You mentioned fuel and the correct fuel is the key to getting a good clean gas.
That looks to be a nice unit. Thank you for making a video for us.
good info to know, i like to see stuff out of the ordinary like this.
great question. on Mine I use a battery and inverter to start the blower. Once the gasifier is running the genny takes over and your recharge the battery plus do whatever else needs to be done. You can also just run a small genny to run the blower till you get it started. Thanks for watching.
Learn proper use of a camera. Your videos are nauseating.
I think I'd want to thread the end of that flare and use a removable tip so when it wears out with the heating/cooling it can be replaced.
Thanks for the video i will be trying this for sure
I need this!
If you make a gasfire the main thing is to clean the gas , or make some kind of filter
Use the wood gasifier to run a generator, and in return use the generator to operate an electric bandsaw sawmill.
Great video brother
Gasoline engines running on wood, gives me wood.
wood gas if filtered right and the gasifier is running hot enough to crack all the tar , then it is just as clean as propane. thats why he talked a little about wood prep too. you want the right size wood chunks (to avoid bridging) and dry is key to getting high temps(to crack tar). one of the draw backs is running at high temps(1800 degrees) is most metals cant take the heat and metal will disintegrate.
I have a series of videos on cordless chainsaws that I tested using a solar power system to charge the batteries. TH-cam gave high ratings to the first few where the Greenworks 40v saw was the winner, but later I found the Oregon PowerNow saw to be a higher performance saw, just with shorter battery life. They don't make DC chargers for the 40v saws, so you need an inverter to charge the batteries from a DC power source but that's getting firewood without buying chainsaw gas.
Wow, what a great development. Thank you! It gives us some great ideas.
i like this project
Could you use a bellow like for pumping up an air mattress? or would you need something more consistent and powerful?
so for the long term how dirty do the internals off the motor get??? i still love this idea for generators
Any advice on storing wood gas?
I've not seen many people do it, but when they do it's kept at low pressure. I guess a well ventilated area is best (CO poisoning risk)...
I've seen WWII era photos of cars with it being stored in big bags on the roof. (The bags need to be big to be useful because of wood gas' relatively low energy density.)
I'm sure the blower helps it get started faster but do you need it to the fire hot enough in the chamber for the system to work?
So, after its up and running can you continuously add fuel and not worry about it?
Could you burn treated fence pickets? Those are always plentiful after a hurricane.
Not to cook with, jusy for generators.
How long will the gasifier run the generator or whatever your gasifying and how long will the filter system last before having to change it
Are there issues with the generator running too rich or lean on wood gas, or does it just run as it would on regular gas?
Good trick , no electricity so build/use a gasifier & then use a electric blower which requires electricity to start the gasifier .
I think DC batteries would work...lol
Good point and very valid.. how the hell do you start it without an electric fan to pull suction
You can use:
- Hand Crank version.
- One from a solar panel.
- One powered by a bicycle.
or an electric one from your Off Grid Battery system. He just used the electric one because it was easier to demonstrate the process.
what did you have plugged into the genset for a load?
Can you do another video explaining what is happening here. What the other changers are etc. ?
You can check out (Compressing wood gas into propane tanks) Langston's Alternative Power
How long does the car lease yellow last before she burns off? looks interesting. Is the only way to get this rolling with electric fans which I wouldn't have in a disaster? Thanks!
hello engineer 775 great demonstration of the leaf. but I didnot see any blue clean gas from the flair test. How do you know you got clean gas going into the engine? Thankyou Keep the faith John Millard
Is it dangerous? What happens to the heat? Can the heat be drawn out of it and used? How many hours will it run until the generator need servicing? Can you use a car battery with an inverter to store the energy for the blower?
Looks like they did a nice job on the manufacturing. But is this a FEMA design? I can t see that blower holding up very long, I used similar blowers in the beginning and the acidic moisture in the gas destroyed them. But still a nicely built unit.
Very robust design. Could have that thing roll down a hill and be able to be up and going. Some people just need to know that if you have this. You are going to have three options to start and then utilize it's output. A man can't video every option. Just worked with what was handy. Love to see follow up's on how people have modified your items to fit their needs.
Sooooo you guys know that FEMA came out with a 90 something page book on how to build one of these right if not and your on an iPhone I would consider looking it up and putting it on your iBooks it's pretty helpful if you want to DIY one of these bad boys
Fema Gasifiers suck. Build an Imbert type or ruin your motor.
The FEMA gasifier is not a bad starting point, but Ben Peterson built on that knowledge with a lot of hands-on experience, and published "Wood Gasifier Builder's Bible". I would recommend that anyone considering the basic FEMA build, first at least learn about Peterson's work, and decide from there.
Scott, is there any adverse effects to the internals (piston, rings, valve, cyl) of your genny when using wood gasification? Can wood gas be applied to a diesel genset with glow plugs or is it required to have gas/spark plug setup? Great video!
From what I know, there can be problems if the syngas isn’t filtered properly. There are tars and moisture that comes out as a byproduct of syngas production, and those can be filtered off in a variety of ways, but it needs to happen regardless. If not, the tars can cause the engine to seize, and the moisture can corrode parts.
I like your videos
how much did the unit cost that was in the video?
Can you use the fuel to power a hight velocity torch
What is it made of? Stainless?
thanks
could provide the plans for the construction of the gasifier
True but hard it can be difficult with a bellow or a blacksmith hand crank blower.
Without gas purification of contaminants. Illustrated example being tar. How short is the life of the generator motor?
hey engineer775, have you tried to make portable wood gasifier stove? I think ill be the ultimate bob stove, no fuel to carry, easily available fuel and able to burn wood w/a very small smoke signature. and if you already have a few tools, all you need are some empty cans and you could make them in the field!
apparently it works but its WAY more realisitic to run a gasifier on a car. not brilliant mileage but considering cars in my country are often ran on propane (including a few on my channel as well as my daily drive), I think it'd probably be my best stealth option. cops would go nuts seeing a gasifier but not a propane tank they assume is filled with propane but actually filled with woodgas.
I found a video telling you how compress wood fire gas into a propane tank. I thought you might like it. since I can't post the link here search "Compressing wood gas into propane tanks" on TH-cam. I hope this helps.
Hello !
What are you ship to France?
Do they still sell these I cannot find them?
"it will not run a truck" interest lost temporarily. 5 words later i was excitet hehe
WoW!!! 4500 bucks for that!!!! My M-II is twice that machine for less than half that cost.
I tried searching that website on the gasifier but the link doesn't exist
if it is full of charcaul will it fire up faster?
How many pounds of material per hour.
i want to order this, what is the price?
of course its safe for engines. 90% of vehicles in sweden had it in ww2 after the world cut off their oil ( they would sell EVERYTHING to the nazis ). the nazis themselves used it and some of my relatives used it here in australia during our fuel rationing period in WW2. gasifiers have filter systems on them or the draft going the right way to avoid crap getting in the engine. hardwood is best, nonwood is crap. But I've got gas from wet weeds ( had to heat it and had a lot of steam first )
great stuff. can you do a video on how to make a generator quieter so nobody will steal it
Put it in a well secured shed
Are these still available?
there is a guy called wayne keith who has about 4 trucks he has gasifiers on. his ones use a 12V blower like a car heater blower. He's on YT and starts a V10 dodge ram in 2 minutes using a blowtorch.
It was hard to hear what was being said. Next time try putting the fan further away or in a box. That would probably make it easier to hear you guys. Thanks for sharing. Best Wishes n Blessings. Keith Noneya
Are the wood gas stored
Recommend Wayne Keith's DIY gasifier. Google "drive on wood"
Ok, the amount of time and energy to make such small pieces of wood would be insane. Also don't use a electric blower to start it, in grid down you may have none to use.
A gasification system that can use the same wood as a wood stove is what's needed.
I looked on line to see how much it would cost for one
If had no blower....Bellows worked back in the day!
That solid looking construction and parts no disrespect here but I can get one delivers to my house for 2,500$ comes with a cook top stove
you can get the Chinese stak or what ever it's called for that kinda money. it's not the same at all. cooking grade wood gas and engine grade wood gas are two different things. I know people that bought the Chinese version and we're disappointed with its performance
@@tritowns So do I. Don't buy FEMA!
hey if you ever dig up any gem rough while you are digging those wells let me know i facet stones and cabochans... might find something to buy a million gasifiers!
IF U AINT GOT 'LECTRICITY HOW DO U RUN THE LITTLE BLOWER TO MAKE THIS THING MAKE 'LECTRICITY?
That’s my question too. Not being a smart aleck. Maybe you have to keep a few batteries around and use one of those little mattress inflator blowers.
You need to do a more concise video to show exactly what has been accomplished here. I am not a nay sayer because I know this technology works, its worked ever since before WWII. Joseph Maximus has a very valid question about running the blower when there is no available electricity. Would it be common sense to have a battery back up with an inverter to power the 120 volt blower to start the system? Having a longer video describing more of your operation also stops people from asking stupid ass questions and wasting other peoples time. Anyways nice job. I would axe the yellow paint though and paint it camo or forest green. Just my humble opinion.
I'd imagine you could substitute the corded electric blower for a lithium ion one (I use them to start my fire pits - very effective). If your batteries were not charged, well, then you'd have to go with Egyptian bellows.
so if I'm correct u need hydro to create hydro cause of the blower whats the point
jason hisey
Not true. Some people use a 12volt blower powered with their car battery. Once it’s going you shut off the blower. Several steps were not shown in this video demonstration.
Ok that is cool but how are you going to get electricity powered to the leafblower, if you don't have the gas in the tank
You can use:
- Hand Crank version.
- One from a solar panel.
- One powered by a bicycle.
or an electric one from your Off Grid Battery system. He just used the electric one because it was easier to demonstrate the process.
I am confused....how are you supposed to use that little air pump to start this thing if you don't have electricity?
You have to have some stored energy to start, such as the battery in your car, or lithium batteries powering an inverter. Once the gasifier gets going, the battery can be recharged.
preparing all that wood would be a ton of work if you didn't have enough gas to run the chainsaw. this seems like a good option to supplement your other preps, but not a serious solution.
Make a video showing how to make a bellows
2 check valves and a bag of some description to capture your air.
Or even buy an air mattress pump.
Why not condense the gas coming off of the initial gasification process and get all of the tar out, Keep your engine healthier.
great idea ... make it easy to sevice
The gas will not condense. But the design we see already has a filtration system to get all the tar out.
Can you turn gas into liquid gasoline by condensing it? From biomass.
Pyrolisis oil is a high cetane fuel, like diesel. So perhaps you could filter the oil and use it in a pilot injection engine and change your fuel filter very often. However its not the same reactor design (FEMA gasification) as the DIY kit here.
Pyrolisis is the process I want to do. You know how pyrolisis works right? I think you heat the biomass and it gives off a flammable vapor. So you use a filter somewhere in that process to clean the gas? Then after that you can now put it in an engine. If I am wrong then can you please correct me? Can I send you a link of two videos I found that talks about pyrolisis?
the efficiency is very bad when you convert to wood to liquid fuel. youll use a lot of waste heat to generate Pyrolisis . better off using wood gas (syngas)
Ok. I can try to do it in an efficient way right? If I found a way?
I beleive if a Catalyst is added to the gasifier number 4 grade diesel can be produced instead of the syngas.
And there's another thing! What I cannot understand among all these wood gas enthusiasts is why nobody has tried turning the stuff into gasoline! Its actually not that difficult. The Fischer - Tropsch process need a pressure of around 5 atmospheres (car tyre pressure plus a bit), and a temperature of 300 degrees centigrade. As feedstock it needs carbon monoxide which is what woodgas is mostly composed of. Discuss please
To 779: The link to your production units page is 404. I will remove this when the page works or you otherwise respond. Thanks.
engineer. could you please do a video explaining how a wood gassifier works and its' operation. please excuse my inexperience. ;)
I too am interested in how this works....But if I can run a generator on wood compared to sky-rocketing gas/propane $$$'s...$4500 is a good deal.
Wood emits a gas when burning. this pumps the gas into your motor.
+Jared Maxwell Not exactly. If you heat wood to a certain point you can get it to degas, and then you are left with charcoal. But the temperature changes what gases come off, and also changes the content of tar and creosote that will be deposited into whatever is using said gasses. Look into making charcoal, it will help understand the process.
Without gas purification of contaminants. Illustrated example being tar. How short is the life of the generator motor?
Is the wood gas safe for engines ?
Does it make the generator engine oil dirtier faster than gasoline ?
Can this type of unit use any kind of wood (soft, hard, large or only small pieces) and can it also work with biomass (leaf, grass, straw) ?
thats weird cource denmark norway finland and sweden ran 85% of their cars on these units for the whole of WW2..and many continued up until the 1970 ,,and we still have plenty of forrest,,,
how do you turn it into liquid gas?
He doesn't, and likely can't. "Wood gas" is a mixture of gases like CO, H2, and I don't know what else. Each of those has a different temperature at which they are liquid, and H2 would have to be cryogenically cold, or under extreme pressure, or both. Wood gas can still be compressed, though.
steam > imo
Why is website down?
What website would that be sir?
and under load that you did not show???
no load, it's all so much easier to do.
Sure looked like a lot of smoke going into the generator.
Yes. Compared to a Drizzler gassifier, it was a VERY dirty flair.
Hello Sir I have been watching your Channel for quiet some time. If I'm not mistaken you and southernpreper 1 have started this business called practical prepers together. Does practicalpreperscom have its own youtube channel? If so let me know I would like to subscribe.
Thank you for your time

No smoke is great
I honestly feel this is could be great use for storm clean ups being as much as 80% of debris from homes after a disaster is wood - If several LARGE trucks or a convoy could be brought in to process all storm wastes lets say like after Katrina and immediately start bottling the gas and tar I know it would save millions on cleanups and also be better for the environment compared to landfills. Why nobody is aggressively studying this potential is something I don't understand. Unless its simply the Oil Lobbyists keeping it unsupported
There are huge commercial Gasifiers in use all over the World.
Google it.
could you sell me the project?
so much noise, cant hear what
you're saying. shoot video and
then dub over it with your dialog.
a Quick walk through description
of how the unit operates would
be really nice too...
That smoke is still pretty dirty
Have you tried human waste?
Put it on a trailer and run a motorcycle if you needed transportation bad enough
7 years after video posting - Today California democrats can't keep the lights on - Gasifiers would be a great investment for anyone living there.
Respectfully, I disagree. You'd probably have to get a permit to gather wood, or fund an environmental impact study to ensure the loss of termite food did not jeopardize the food chain. I exaggerate only a little. I was talking about heating with wood and really did get an objection about that, and I own 50+ wooded acres, not in California.
$4500. I'd reco'm
Looks like a good unit but the workings were not explained at all by the presenter. No information about valves, their settings or anything about the basic workings.
>>-------------------------------> Wow, from their website >>> "$4,500.00" plus shipping. (I guess poor people need not apply)
dang wynot free? people don't needed money
NwoDispatcher
Steel is getting expensive. But you can't build it yourself for less than 1500 probably.
surearrow
you could always find three poor people to pool their resources.
4500.00i is not a bad price if it repeatably produces clean wood gas. don't expect that from those chinese units, they are junk. I would recommend that if someone feels they can do better, start a company and build them for a lot less.... I'd order hundreds from you if you can actually build a unit that makes good gas, quickly, using soft wood chips... that's what i currently run in my system.
and your time is worth nothing... and does everyone own welding gear?
i build gasifiers... not new to this
i don't build fema systems... i've looked at your channel, i see you haven't posted anything... shows what you know
you don't know me... my system works as well or better than most so i doubt i'd need to copy anythig you do. i don't post my internals because people like you would claim i stole your idea... you are a troll... i'll make sure i point that out.
not gonna explain my system to you, don't need too... i have vids of it's operation... something you don't seem to have..... troll
tritowns
oh, Engineer... feel free to delete anything here if it's out of line... keep on keeping on
This is a downdraft wood gasifier, period. It is NOT imbert in any sense. It will not generate high enough temps to crack long chain hydrocarbons, thus you will be sending tars to your engine and eventually tar up the valves and the engine will fail. Pull it apart to untar it and "start over"- I think not. This is nothing but an expensive FEMA downdraft wood gasifier. You need to go back and understand the chemistry of producing a tar free product. Waste of money!
No, this system uses nozzles.... nothing fema like in this unit
more better to learn to live without electricity and mucho cheaper,,,,ole fart Jimmy
This look spensid , but i have a better idea it dont cost me nothing but few dollars
