- Thanks for watching. This is my homemade gasifier. In this video, I will explain how I made it. I will also give you a full demonstration.
How to make a generator that runs on a gasifier
• Lawn mower turned into... - วิทยาศาสตร์และเทคโนโลยี
Thanks so much for making this video. You show how to make this out of affordable easily obtainable pieces. Your explanation and demonstration was an easy to follow one. Watched a few folks showing and explaining their units. Yours was the easiest to understand. Thanks once again.
You talked as if to your best friend, making sure he understood. This video should be in the Smithsonian for all time, an historical artifact of the times.
Wow-what a great comment. Thank you so much for that.
Cool...addition to the radiator...get old messed up welding rod...smash off the flux...then tack them horizontally across the radiator pipes to increase the surface area, better passively cooled radiator
Cool design...definitely would like to see more detailed instructions/welding/construction of the generator! Very very very cool!
Thank you for your comment. I believe it goes without saying, I am great at designing, but super shitty at welding. LOL. I would be happy to make you up the complete details on this build. just shoot me a DM and I will detail it out to the best of my written ability.
That was cool. 100% home creation...1000% science...thanks man
Finally, someone who just goes step by step of the major components. Thanks for sharing. Yo want to sell it?
You are very welcome. I still have a lot of build left on this project. I’m also designing a hydrogen cell for another generator design that runs on water. Technically hydrogen gas, but that’s just pulled from water.
Nice concept. Gasifier on wheels. Who thinks of that? 👍👍👍
I built part of one few years ago I think I'll finish it I see you have a awesome setup I need a few more things to build but putting some of your ideas u have I hope it burns as well as yours .you rock brother keep moving forward
Yo viví en Wichita en 1985, amé ese lugar! Muy interesante el video del gasificador
This is by far the best explained gasifier video I`ve watched, thanx.
Man Pete that means a lot. Thank you
Thank you. Nice build.
Brilliant, simple uncomplicated and works great.
Thank you for sharing with everyone.
You are very welcome. Thank you so much for your kind words.
Very well explained! Great video. I just found you. Keep up the good work and I will be watching from Texas. Now I have to get back and watch some of the other videos.
Super Awesome! Thank you so much. I just moved to Texas this week. Austin actually, so all my next videos will be right here at home for you.
Really good explanation! Thank You from Sweden.
Thank you so much.
Wow.. i think i saw the best gasifier video.. very well explained so easy to understand!! 👍👍👍
Thank you very much
I would agree, after watching so many other TH-cam videos on this subject this one finally allowed the penny to drop and taken the mystery out of wood gasifiers. Excellent well done for the explanation. I'm left wondering if a modified version could be used to heat a building?
Nicely done! Thank you!
Thank you for watching.
Good job
Yup. Liked it.
Thanks for the knowledge
you are very welcome. Thanks for watching.
Great 👍
Great build! I'd pay you to build one for me .
😁👍

Overall a nice setup!! There are a couple points though you may want to revisit. The combustion gases coming off your cyclone filter are still going to be hot, so I'd hope you have used a metal seated ball valve (what you called a control valve) ahead of your radiator as the gas may be hot enough to melt cheaper plastic seats. The after-filter catch bottle should not be needed if the filter is working as the gas should not have undergone enough thermodynamic change between the filter and bottle. Where you would really need that bottle is below your radiator. You have a liquid trap in your piping between the current after-filter catch bottle and the radiator. As energy is removed from the gas in the radiator, and steam condenses along the pipe walls, the trap may eventually fill, and you have no means of draining it. This can cause slug flow in the gas and burping in the system. If you build another, you may want to put the radiator between the reactor and the cyclone filter, and add fins (or buy finned pipe) for the radiator to extract more energy from the gas. The more steam and contaminants you can remove in the cyclone filter the less smoke which should be produced. The bed of shavings should only be for polishing the product gas. But again - what you built is among the nicest I have seen for a personal installation.
Great input, thanks.
Very good input. I have noticed that between burns I need to drop the bottom pipe leading into my radiator to drain it. I think I will take you up on the suggestions. Thank you
Do you know of a site with more complete plans, with information like youve noted? Just asking be handy
@@dw-yc6qb Sorry D, I cannot say that I do. I've near 20 years experience in various process designs working in primarily oil & gas, so I just extract from knowledge gained through my education & career. Best I could suggest is you'd be looking for either chemical engineering or physics literature regarding pyrolysis. Then do a bit of a dive into material compatibility for higher temperatures with the combustion gases and condensate. Some phase equilibrium knowledge is helpful too when considering the oils & tars which will be produced. Hope this is of some help.
@@Aukage Cheers will have a bit of dive into what you have suggested, i have downloaded some plans but they are bit thin on detail but will keep at it thanks again 👍
I liked and subscribed
Great work
Thank you
Totally Awesome my Brother
Thanks so much
Thanks for sharing 👍
Very welcome
Thanks for sharing, nice job and good explanation.
I am thinking of building one of these, great to see you have used a somewhat smaller tank from an air compressor, the FEMA drawings show you have to a have much bigger reactor from an oil drum or something, and I could not understand why it had to be that big - now I can see, that a smaller one wil do the job, so it answered one of my big questions, thanks.
you are very welcome. Thank you for watching
That's some a+ welding
Clearly, I am not a welder, but I will trade the ugly welds for its function every day of the week.
Subscribed fo sho!
cool
That's really excellent. 👍 This is quality work you have done Sir. 👌 You could run a gas or propane based genny almost indefinitely, as long as you have some wood chips to feed the main reactor. 😃 The only downside I can see is you are making enough noise to tell all the bad guys (Wolf Preppers) where you're at so they can come kill you for your generator.🤔
does it give off radiant heat as well as useful gas? so I could use this as a wood burning stove in a garage as long as I use proper ventilation and safety, or run a heat exchanger off the outside to heat water like one of those woodmasters?
These open type gasifiers can leak some carbonmonooxied into the air, so if you run it inddor, you risk air poisening. But a heat exchanger instead of the simple radiator is a great idea, the more you cool down the gas, the better it is.
Before your video i never new what the heck gasifier even meant. This is absolutely amazing. I saw the engine video running and I thought it was simply using the over heated air to create a combustion.
Thanks. Yeah, I am working on making this a complete self-sustainable mobile grid tiny trailer. Eventually, I will be able to harvest wood into wood pellets, convert wood into wood gas, store energy through a battery bank and even produce diesel fuel all off of this 3x4 foot trailer. I literally started building my reactor today for converting plastic into diesel fuel. I will have that video up soon.
Perfect......now, just need a video showing us how to store the gas into a propane bottle ;)
No you just connect your devices directly to it like a lantern stove lawn mower whatever
It's not recommended to bottle because it is a gas it doesn't stabilize like propane or acetylene, it looses it's potency in a very short time when pressurized and store. It's meant to be a fuel in demand system
@@BigBeavrSlayer Great input, thanks.
@@christiantrab6160 there are several people attempting to scrub clean the gasses that destabilize it to make it safely compressible, but it seems a gasometer is currently the most effective way to store it but that is in small amounts. Thrive energy is pushing this project right now with dual gaso meters that run on demand through a gassifier, he has made some progress in the last 2 days
Wood gas not easily stored but I've seen submerged tank bubbler style storage but not sure if gas picks up too much moisture to use in generators after this
I'd like to adapt an external gasification system to my outdoor wood boiler that I use to heat my house. Instead of it venting to atmosphere, might as well see if I can recapture some of those unspent gasses and run a generator off it (even if it's just enough to run my boiler's circulation pumps that would be great).
That would make a great setup. I spoke with a man about designing a system similar to what you're saying to heat his chicken coupes.
A down draft gassifier is different than your wood boiler. In your case, you'd be best to put a cyclone on the exhaust, then through a radiator before putting it into a generator.
For what you're considering, start with a downdraft gassifier and put the engines exhaust through a radiator, blow the heat into your home from the radiator and keep the electricity
@@kevincorapi137 High efficiency outdoor wood boilers are literally downdraft gassifiers already. You can't just take the smoke from your inefficient, fire inside a water tank, boiler and clean it up to run a generator more than once.
Thank you for the video
You are very welcome
I like your build you have done your homework. The trailer idea is awesome too I built mine on a trailer too you can tow it with a small cc car or stationary for generator or use a Retrofitted refrigeration compressor and fill propane tanks with with the sun gas and make due the propane tank is pulled down with vacuum before filling it can go safely to 300 psi and used for cooking heating or refrigerator as it is mainly methane carbon monoxide natural gas. And it’s all free could be dangerous if your careless Ben Peterson’s design is dang good too just got to have some common sense if not then this ain’t for that person. I’ll stop I can’t say enough. Cheers
Thanks for your comment. I certainly appreciate all the good information. I definitely want to try storing the gas for future use. I will check out that Ben Peterson you suggested.
Great explanation nice compact simple design. Does it need constant adjustment to run a generator or can it be left running for good amount of time? Is this gassifier big enough to run a small 240volt two plug generator?
I get around 8 hours of burn from one hopper. A couple bucks worth of pellets. As long as the ash grate gets shifted a few times to keep the air flow it will maintain its burn just fine.
How big of a generator can you run with this? Does the gas produced from this tax the generator more so than “fossil fuels”’would?
Thank you. Do you think that a bong-style water filter would work better with this kind of setup? Seems like it would cool & clean the gas.
I think that style filter would work great. It would also act as a cooling medium for the gas to burn easier.
Imo the gas has to be cool because of the fan and that the moisture could condensate. So for a bubbler a reasonable position temperature wise would be before the fan, but there is a suction wich would work as an air lock(creating vacuum in the bubbler wanting to suck out the water)... so it only can work after the fan where the gas is pushed. Also might introduce extra moisture into the gas. Isn't it?
@@lorifilm yes you are right.
ive seen a imbert design from the 1940s that had a bong style air cleaner
@@lorifilm Bubblers work just fine with suction, that's how bongs work, you don't blow into them! 🤣🤣🤣
Nice job describing. What's aize of hole in tube for drip jar? I would assume very small diameter.
Never mind I can see it is air tight as well so diameter doesn't matter much.
Best explanation ive seen so far . but can to tell me how long will it power a 5hp gen or what ever size you use . i need to see if its practical for me to build one ?? also do you have to be going out to constantly adjust the flow as your hopper burns down ??
ive seen one that ran for 24hrs and only burned 6kg of wood pellets . wow
Any information on hopper specs... diameter/ length? Assume it has a funnel at base where it has to blend in with burn tube diameter? Good design . A plan is to make similar in Tasmania..
My hopper is 6" in diameter. The ignition tube that ties into the hopper is 2" pipe
how long can it run without interruption?
Wow sir, that's awesome that you built that in your back yard! Can you tell me if your system allows for storage or bottling of the gases being processed? Any reply appreciated.
Yes it can be bottled propane style. I have not pressurized one myself, however I have watched another’s bottling system work. I have not been able to work on this project in over a year because I moved to Texas. My machine is gathering dust in my brothers garage in Kansas.
Would it better to put the generated gas into a small engine belted to a 12 volt alternator / car battery charging system then produce the 120 vac with an inverter - in case the RPM might vary off generator system? Trying to generate 120 vac directly requires the generator run at a fairly steady and constant speed like 1800 RPM.
Yes I think that would be a better set-up
Other than allowing RPM variation when using a gas generator some of the other benefits is that the power system is more modular, and self repairable from components you can afford to keep in your home. Group 31 led acid batteries or Golf cart deep cycle batteries are readily available and almost economical, the automotive alternator like a Delco Si-12 is inexpensive (commonly used in mid 1980's GMC vehicles) as are multiple commercial inverters in various sizes. Delco has a great tech site they let me know most alternators can safely run up to 15,000 RPM. A large 10 to 12 inch dia taper lock hub pulley for the motor works well for this. A variety of bore diameter pulley taper hub bushings allow swapping out horizontal shaft engines really easy.
Great explanation. This clears up some questions i had and how it all goes together. If you had to put a price on pipes, valves and tubing, roundabout what would i plan on spending? I am able to get the tanks, fan and misc other materials.. ty
just off of memory, I think I spent around $120.00 on all the plumbing
@@Saxxsays 120 as opposed to Ben Petersons 1000 + I know who my money is on, well done and thank you from UK
@@Saxxsays damn now I can't use the excuse it's going to cost too much to build time to dust off the welder😂
@@PedigreeMongrel yes, dust it off. Heck, I can hardly even weld. Just look at them ragidy beads. The point is, things are scary in the world right now and time may be more limited than one may think. Best to do it now.
Right off the top of my head it was all under $100. Or at least very close to it.
How did you build this gasifier ?
Good video. Two question...where does the wood go and how to you load it?
I apologize for being off line so long. To answer your question it loads at the very top of the hopper.
What would you say is the average cost and the average time that this build would be? I love the thorough content, thank you!
I'd say you could build one in a week if you had a few hours a day to dedicate to it. I used mostly things laying around the garage. However,
the plumbing is kind of a hit to the wallet. Aside of me already having a tank and something to use as the cyclone filter I have around $400.00 in the build. Everything bought at Home depot.
It depends on if you buy the materials new or salvage them used and what you want to run with it. I built my unit for about 500$ and power a Chevy V8 with it
So, if I understand this right, you're making wood into flammable vapor, that's then being used to fuel another device? Can something like this be made from a stihl, or perhaps, a drip fed waste oil burner?
Absolutely you can use most anything. In fact, it does not even have to be a cylinder. T
he most important part is that it must be an airtight system. It's all about a restricted oxygen environment so that you can reach paralysis
in your burn to create the reaction to release the wood gas.
@@Saxxsays gotcha. Out of curiosity, can you do a video later showing just how long this thing can power sat, a simple generator? Or anything. I'm just trying to grasp the idea of how useful wood gas would be for other applications. I've only ever witnessed it being used for heat, light, or a combination of the two.
@@northwindhighlander I have a video on my channel of it running a mower if you want to check it out. But basically, with my particular build, I generally load with wood pellets. My hopper fills up around 4 times out of 1 bag of pellets. The bag cost me $5.00 at home depot. The hopper will burn apx 4 hours without adding more pellets. That will create gas the entire time and run a 7hp generator non-stop until the fuel is burned. So less than $2.00 every 4 hours of continuous run avg. So comparing that to gasoline, its no comparison. Also,
you do not have to burn pellets. I can run it off of sticks in the yard for free. Its just easier to run consistently with a more even burning fuel.
i hope that helps. A 4 hour video may be a tad bit too long. lol
@@Saxxsays that totally helps. I'd assume you're running the fuel into the air intake? I'll have to check the whole channel out. Saw your video in a Facebook group earlier. Seemed interesting. Thanks.
Good work. Why not insulate the reactor? How about some instrumentation? How long does it run before you have to reload? Why not scrub some oxygen out with clean metal turnings..
Thank you. I plan on insulating the reactor at some point soon. It would be great to automate it. Soon as I can afford to throw some more money at it, I will be trying some upgrades.
If there is any oxygen in the gas stream you are doing it very wrong! 💥🤦
Well you've got my sub. To me, this is a miniature replica of a treater vessel (or scrubber), at a gas plant. I wouldnt even doubt for a second, if you were an oil and gas engineer.
I would maybe cut down on the power, with even a speed control module, by using several CPU fans. You could likely power it, just from it's own production.
It'd be much easier, with a proper valve system, to change or do maintenance. Some great effort went into this. Well done, I surely could not do better, and haven't seen anything better to date.
I know Im randomly asking but does someone know of a way to log back into an instagram account??
I stupidly lost my login password. I would love any help you can offer me.
@Huxley Jaxtyn Instablaster ;)
@Abdullah Daniel Thanks so much for your reply. I got to the site on google and I'm in the hacking process atm.
Seems to take a while so I will get back to you later when my account password hopefully is recovered.
@Abdullah Daniel it did the trick and I actually got access to my account again. I am so happy!
Thank you so much, you really help me out :D
@Huxley Jaxtyn you are welcome xD
I'm gonna apologize now, because I quite honestly had no clue this type of system existed up until this point and I don't have much knowledge on how liquid based fuels are created. I just had a question as to how and if you would be able to turn the wood burnt vapor into a liquid base? I see its easy enough to just rig hoses to carburetors in the case of a generator, but running lawnmowers and other such machinery this method isn't quite suitable as I'm sure you're aware of. I'm just hoping to learn a few things about this as I'm very interested in living the tiny house/off grid way.
No, this particular system won't work for getting liquid fuel. However, it can be pressure bottled such as propane and run in an air gas style mobile machinery. Now if you were wanting it for like a riding mower then you could absolutely do a simple reactor micro-sized that you attached to the mower.
@@Saxxsays very neat stuff! Thank you for replying! And thank you for putting these types of videos up! Very informative and hopefully it will get a lot more people interested in not relying on big corporations to live sustainably.
The best effort on this was done by Mr. Teslonian years ago. But I wouldn't mind to fill that into my car ;) If you prefer this way - perhaps you have a look on plastics gasification.
@@ravelkoff3549" plastics gasification".. another thing I had no idea existed! Haha! Thanks for the input!
@@royalenomadicimagery8157 ur welcome buddy. ;)
My dream is to one day have a mini home powered by a generator that is powered by wood. I could be 100% PG&E free !!!
and you can use it to charge up your electric car when the sun isnt shining too much
How long does it take with a full tank?
Does the gas cause any damage to the carburetor or engine over time?
please answer this question!
Thank you
It will run for around 6 hours on a full hopper. The cleaner you filter your wood gas the more long levity in your carbs. But if you are burning more contaminated gasses it certainly can begin to wear on your carb. Particularly your seals or gaskets. Overall don't slack on your filtration and you will be good as gold.
It seems to burn very clean I guess all of those drip jars act as a scrubber. I wonder if this will produce enough gas to run a 15,000 watt gasoline generator?
Absolutely. You will just need to fine tune your burn to your climate. Gasification is very temperamental
Well the whole idea is if the power goes down you can run your generator off of that but you won't be able to start your fan on your gasifier because it's 110 if you don't have any electric a smart move would have been to put a 12-volt fan on there so you didn't need electricity to run the fan just a small battery would have done the trick even a car battery if I was you I would replace that with a 12-volt fan p I suppose you can always put a inverter on a battery and run it that way but it would seem like a smarter way to go is it 12 volt fan
Yes absolutely. The fan is temporary. It will have a combination of 12 volts and inverted power to charge after the machine is running. This is still all in the making and design phase.
Small inverters are cheap.
I would put a bypass around the fan for when it's running a motor, as it just becomes a drag and increases wear reducing it's lifespan.
SHOW!!
How do you shut it down when done using it
Just shut off the air valves to it. Turn off the fan
What is the model of your matress pump
I have no idea. The one they had at Walmart when I went to get one. I would look at it and tell you, but I am in Texas and my machine is in Kansas. I’m sorry.
My problem now (in mind) will be the pipes...
Where the hell will i find non steel pipes?
I heard steel pipes are a pain to weld.
if you use it in a grid down how will you run the fan
This is only the beginning stage of my build. I am adding a generator that the gasifier will run which will charge the battery bank I am installing. So here soon, it will not depend on any outside source of power.
@@Saxxsays all you need is a 12V lead acid battery (almost any size will work), $10 DC speed controller, and a $20 marine bilge blower
@@rotaryenginepete Right but I would recommend a $10 air mattress
blower because of much more power. And a PWM controller would be the best decision to control that.
@@ravelkoff3549 that is what some people use but a mattress blower is not rated for flammable vapors...so in addition to depending on an inverter to make it work, there is a risk of igniting the wood gas.
@@rotaryenginepete Hi, I use it since 3 years. There was no spark, no air to ignite (after sealing it) and no risk at any time (as I see in my experiences) And the throughput of this little guy is the same which my engine has. I also tried a bilge blower and the only thing I was not glad with was its power or its throughput. No need for an inverter if you want to use a 12v battery. A12V PWM module is only for percentual speed downstepping.
When its good for you - fine so far ;) I tried to give you an additional option for this being able to run it on 12V. Bless you :)
Make a filter and we could burn garbage.
He has to because someone has to pay off that 4 trillium stimulus
No kidding.
Not free
Good God put the welder down those are some of the worst welds I've ever seen
Lol, yeah clearly I am not a welder, but I certainly made my project work. So imagine how good it will be with good welding skills.
Someone does something… someone else is the critic…
Good job
Thank you very much.
