sorry my friend couldn't hear anything you said
I could hear it. He was saying " blah mmaamamahahhmma blah manaumm"

WHAT DID YOU SAY?!!?

WHAT!!!!!!
Huh?
Pardon , what did you say?
most of this video I can't hear a word your saying. consider removing the video audio and recording a replacement audio without all the background noise.
When you can't see the gas burning you've got the purest gas you can get excellent job
He's got an compact industrial gasifier for sure. The problems with those DIY ones you see on UA-cam everywhere is that the filtration steps and efficiency is lacking.
If one lived in a highly wooded area, something like this would be perfect for SHTF. Quite a few lumber mills and farms actually run their operation off of gasifier based-power which powers their entire operation + workers who live on site. Pretty neat.
Looks like this is an excellent solution for sustainability. Thanks for the tip. this makes the wood gassifier a good option.
I have a sneaking suspicion that this guy has no eyebrows.
or have burnt beard..
Beat me by a week, I have a similar setup but I added a couple of extras, my 9kg LPG bottle is immersed in a steel water tank approx 4m2, adds a bit of cooling but the main reason was if it goes pop the water takes the impact and you just get wet instead of standing beside a 9kg grenade. I also have a small water bubbler post compresser for a flashback arrestor(maybe I'm just chicken-your's didn't blow). Ran out of time to run the gasifier last week. Will let you know if I encounter anything along the way.
That's smart because it also cools the compressed gas, compressing gas will heat it up a lot so by cooling it you're making it safer as well as the flash back arrestor. Cool setup. Also for the propane tank water bath, if you are using the tank for propane, you could use a pump to circulate the water through a heater to heat the propane if you run into problems with it freezing up (only applies to propane since it's stored as a liquid). Very cool setup, I like the idea of using what's around you vs importing energy!
Hey man, I love you reply. Have you made a video showing your gasifier? I'd love to see the setup.
I've seen a similar experiment before, very cool. I would like to find out if one could use a HP compressor and HP vessels for longer run times in a vehicle, etc. It just seems to be a simpler set up as opposed to having a gasifier on everything, car, truck, tractor, etc. The local community would also benefit from this as well and the infrastructure wouldn't be too complicated for a municipality to set up....I think.
HEAR HEAR! I concur AND second!
It would be interesting to have you revisit this technology after the years and see where we are at. These and ram pumps is what brought me to your channel all those years ago.
Great for running my gas stove and hot water and heater -- well done!! 😁👍
Very neat. I'm assuming wood gas doesn't liquify like LPG when compressed so your limited to just air volume of the tank?
That depends on how hard you can compress it. If you get the pressure high enough it'll liquify. Otherwise it'll just pack in until your compressor can't push it
wood gas is not just one gas, it is a mix of carbon monoxide, hydrogen, nitrogen, methane, mainly, and probably some others. those will all condense at different pressures and temperatures, and there are some significant differences in density between them. some will condense, some will remain a gas, and they will all separate into layers. the majority of the flammable gases will remain as gas, the rest will condense into some type of creosote oil, which will *not* vaporize into a gas like propane does when it's reintroduced to atmospheric pressure.
what's in that propane tank is probably hydrogen and carbon monoxide, primarily, and that's a pretty volatile thing to have sitting around. much more volatile than a can of gasoline or a tank of propane. carbon monoxide is deadly, and hydrogen gas is highly flammable.
Are you purging the tank with an inert gas first? Furthermore how much O2 is being compressed with your wood gas? It would be very easy to create a flammable or explosive mixture in a tank containing air. I suppose once you put enough wood gas in the tank you create a rich mix that cant burn. I would be concerned about the intervening time between the LEL and the UEL, during that period you are merely charging a crude FAE. I would try to cool the gas post compression and keep the tank as cold as possible. Perhaps a orsat or a fyrite would give you a O2 reading on your wood gas?
Really appreciate your work! I know you *KNOW* WHAT YOU'RE DOING. I am not a worry wart by nature. Have dealt w/ LPG. Even refill my own "disposable" LP tanks. But something about this process makes me think *BOMB!!!* Keep a cell phone with you when working on this alone!!! Ipray you have an extraordinarily *BLESSED* day!
THE CELL PHONE COULD CAUSE THE SPARK!
Really? How does a cellphone spark, exactly?
Id be squinting like a bomb squad guy the entire time lol
Most excellent! Thank you so much for always sharing the way cool side of prepping.
As usual, you are on the cutting edge, way to go Scott!
he's about a hundered years behind
This is what I've always had a problem understanding about storage. This really adds a whole new dimension to gassification. Thanks.
Very nice gasifier. I am starting to think it smart to incorporate a storage tank on my system. Put my project on hold for a bit but I am soon going to start on it again. I have a lot of people waiting on new video updates and health is getting better so maybe I will be on it again shortly. Thanks for posting, I needed a little motivation.
thats a nice looking setup, good job. While my first foray into syngas will probably look like an avant gard trash to art project, its nice to have a standard to aspire to
This has been a long term goal of mine thanks for sharing. exactly the setup for my eu2000 and 5k gen set
Would love to see a series on how all this works and maybe a DIY woodgas generator/compressor setup?
This is what you have, this is what you would have to buy!
What do you think Skippy?
This is really awesome, If you could hook this up to a large propaine tank one that goes to a house. You could say run that compressor a couple of times a year to fill your tank. That would be way better all the way around.

404 on both links. Just a general off grid site now.
As in the large propane tanks that I often see in back yards.
wonder if salvage gasoline tanks might work if they get sealed well.
engineer775 Practical Preppers
Probably not. Think air compressor. You pump them up to about 120psi... so most likely they won't hold shape, and would eventually rupture. I don't think they would explode or anything.
Around here (DFW, TX) a used 500 gallon propane tank sells for about $250-$300... if you have a way of getting it home it would probably be the way to go, if not, small propane tanks.
I wish you could redo the video, mute the original sound and talk over the original so I could hear what you were saying. What a great idea. Thanks for sharing. Peace, Reese
How do you make sure there is no oxygen in the Wood gas?
The can could turn into a bomb.
Yes! finally I see someone charging up a tank with woodgas. I really want to know how much and how long it would take to fill a big ol whole house storage tank. How long can it run a furnace, stove, and water heater? Copper tubing to preheat water around the gassifier rig to increase efficiency and reduce water heating loads?
Mark Herndon let me know if you have come across any run time Estimates??
Thank you
I wanna know too😂
Nobody is likely to give you an answer to that because it isn't very long at all.
Back in the war when they ran vehicles on wood gas, they had the gasifier on board and had to keep adding wood if they wanted to keep going. You are probably going to get better results filling a 5 - 10 cubic yard balloon or bladder, rather than trying to compress the gas into a bottle. It takes a great deal of energy to compress gas and, surely, the whole point of wood gas production is to provide an emergency, or off grid, supply of energy., not to use up more power than you will get back from the gas. Another point is that the pressure you get back out of your gas bottle will rapidly reduce as the gas is used up making for problems with carburation or controlling gas flames, You are better off firing up the gasifier if and when you need it and using the relatively constant pressure you get delivered direct from your gasifier. To cover emergencies, you could fill a balloon or two and adjusting carb or burner jets etc. to roughly atmospheric pressure or slightly above. You do need to use a special wood gas rated balloon but even with these, there is likely to be significant gas leakage, especially hydrogen, and there are real safety risks. Far better to burn direct from the gasifier.
It is a pity, but liquefaction is way, way beyond DIY capabilities and hugely expensive to set up the specialist cryogenic and compression equipment needed
I've watched people build these and they think they got good gas because it's burning the flame is just as red as can be so they run their generator it runs fine till they shut it off and it cools down and then all the sap that's in there locks the motor up screws up the valves the cleaner it is the less you can see it you've got pure nice gas if you filled a thousand gallon tank with that machine you could run a generator for a long time but the power went out you could heat a house for a few months the possibilities are endless when you've got such pure gas nice job good build
I was just wondering, the other day, if wood gas could be compressed. Thanks for proving this.
Oh, another thing I was wondering is, if wood gas can be compressed (which you proved can be done), what kind of shelf life would it have.
BC ElginTex All excellent questions to which I hope to find an answer. There is a lot of speculation around. Langstons Alternative Power has been experimenting with this too. We don't have enough history with it yet.
BC ElginTex if you consider woodgas to be hydrogen (its most volatile compound) then it will have the same shelf life of stored hydrogen in a propane tank, if you take the same precotions as hydrogen storage then presumably you could run off of woodgas from the cold war
Hey Scott. Do you still have this stored? Does it still burn as efficiently as three years ago?
What a cool idea and a great experiment. Thanks for that one. I enjoyed it.
That is awesome, what a great way to save on propane, make your own gas! Scott, this was a great comparison too!
This video, more than any other, convinces me of the viability of wood gas. Where to learn more about the chemistry, physics, and practical how-to projects?
Greetings, I really love the ideas I see on many channels about this type of gas. I first seen on Mr. Teslonian's channel about using wood to get gas from.
How about seeing how Hemp would work since that is one of its uses of the thousands of uses. :D
I want to experiment with alternatives, hemp, giant ragweed, even cornstalks. I theorize that if it can burn to carbon, heat, and CO gas, it would work. wood being more dense makes it the better fuel. I'm still in the process of design and build though.
@babysquirrels you can make homemade cement with ash from corn waste? Interesting🤔 I know fly ash from coal burning can be added to concrete; I know it makes it stronger and I think you can use more fly ash and less cement to make concrete
excellent you save me a test on my system. I am using a different type of gasifier but the result is similar. I have been thinking of using an auto air conditioner compressor to do exactly what you are doing and in fact am working on it now. its a bit messy as the lubrication system has to be set up and i think i have it sorted,using a 3.5Hp Honder to drive it hoping to compress to 20 bar, also my neibour has 1.5 Km of 50mm pvc pipe which will connect to my place that's about 25000Lts at 10bar stored in the pipe.
I have done tests on various plastics in the gas and the black heavy walled type pipe is not effected by the gas but the type1 plastic is badly effected and gets a really weird waxy surface as it starts to brake down.
Very neat!
Your video turned out a lot better than mine good job.
That is just too awesome. I have thought about this more than once!
Me too. I just had to do it.
engineer775 Practical Preppers out of curiosity.....how did it compare to the propane as far as duration? were you able to get enough into the bottle to run as long as the propane? I assume a lot less run time for cooking and such but you never know. I thought i would ask. Either way this is just too cool.
I also love the gasification videos. I was just wondering , how long will the propane tank run the burner and the generator for? I always see people run engines on wood, but wouldn't it be cool to see an aircraft run on wood? Or even an entire wood processing plant that runs on wood? In your opinion , is there enough energy in wood to run a wood processing plant , and still end up with a surpluss of stored wood fuel for the gasifier?
A sawmill has an INCREDIBLE amount of waste so I think yes.
@@firebird77clonefirebird89 can the sawdust produced from the local sawmill be used to make charcoal intended for activation
Have you updated your compressor system yet?
Are you still compressing the gas into tanks?
If so, how high of pressure in tanks have you been able to achieve?
I like this subject, I wish I could have heard you talking before 3:40.
More gasification please.
Thanks
Sorry about the noise. My new camera really picks it up.
dubbed voiceover.
the big mistake all of these guys are making is they are not pulling a vacuum on the tanks before filling, one need s a set of ac gauges and a vacuum pump harbor freight has both at a low price and would be ok for this application, to be fully evacuated one should pull a vacuum then let gas in and pull a 2nd vacuum before filling
Leslee Freeman of don't see much of a problem with just compressing the woodgas as long as the tank hasn't sit open while empty for too long, since it should have no O2 in the tank when it runs out propane, once you start to refill with woodgas what ever was last in the the tank just mixes. Therefore negligible amount of propane mixed with woodgas should not be a problem as long as no O2 makes it in. This seems pretty safe with an experienced woodgas operator, skilled at producing consistent quality gas, and proper safety procedures. If anything, pulling a vacuum before refilling sounds like more chance to pull O2 in to the tank. What do you think?
aaronhall555 could a flashback arrestor be used and/or be practical if i were to use it. Being that i am not an experienced by any means and am cautious.
Hello Leslee you seem to be knowledgeable about the wood gas storage please advise me on how to store it in a propane tank and how long can it last and the best method to make sure it doesn't leak I want to store it for small commercial purpose thanks
Why don't you make a video to educate us ?
@@sarchlalaith8836 The point is about safety. Evacuating gets rid of oxygen in the tank. If not you're creating an Oxy/Gas Bomb
awesome.......i gotta build one now......
Go for it Ironhead41!
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
I don’t have any thoughts to add off the top of my head but I remember researching the Fischer Tropsch process. I’ll look at it again and I’ll add input if I have any. I am completely familiar with gasifiers to the point where I’m building a wood stove and might build a gasifier too
That is amazing. Thanks for these cool video's
I think the problem with storing wood gas is its energy density. The whole point of turning wood into fuel is its energy density. You can store a cord of wood and that is equaled to hundreds of gallons of gasoline. The gasoline will degrade in months where as the wood could last for years. Storing wood gas is like canned farts. I think a simple and reliable gasifier is more practical than compressing it and storing it. Plus hydrogen has the smallest atom and will leak out of anything you store it in.
can you do a voice over or something id love to be able to understand it thanks!
Air and gas in a tank at the same time... KABOOM
Thanks for the side by side propane/wood gas comparison. I've been thinking of using wood gas as a replacement for propane for household use (I have a lot of waste wood, so if I can use it to replace my propane bill... great!)
Question: How are you producing the gas? My thought is that a stratified downdraft gassifier adds air to the mixture, which would contribute to the BTU loss. If you're making it in a sealed container (search for charcoal refractory) might get more energy per cuft of gas?
Also, in the video it seems like the propane is coming out at a higher pressure... When Liquid propane turns to a gas, it's at about 110-120 psi, and then it gets regulated down, but you have a consistent 115~ PSI. With compressing gas, you start out at 115~ PSI, and it drops from there.
In the case of my propane tankless water heater that might not be a problem, the propane gets stepped down in pressure from 115~ to ~11psi, and then down to 11wc (less than 1/2 psi). From what I've read online Gas grills run 20 - 30 psi... food for thought. Thanks for the video!
i agree the propane seems to be at a significantly higher pressure, also the burners used could be better designed for the fuel
Wonderful. I’m thinking compress gas onboard a vehicle with the gas used to startup the vehicle and run it a few minutes until the fresh wood gas becomes available.
great info love the idea keep up the good work
Awesome, thanks for sharing Scott! I've been wanting to see this done for a long time.
Is the air to fuel ratio low enough that it would not explode if a spark were to occur inside the tank somehow?
I will be doing this with pure hydrogen gas from a hho split cell I'm in the process of building. I'll post a video of it once everything is set up and ready to go.
thats a really good idea.
I just came up with this idea today , after I saw a wood gasifer driven bicycle..... And just typed in ....thanks for god, and you I found this video....
Whats are your real life experineces with this so far?? How long it last if you use a single camping stove ?
What kind of octane rating could you expect from wood gas? If I remember correctly propane is roughly 116 octane. Just trying to see the feasibility of running compressed w.g. in a vehicle built for LNG or LP .
Thank u for your replies. You have very informative videos that make me jealous : )
I got my bowl of popcorn, fill up some more tanks ; )
It's dangerous to compress wood gas because of the possibility of oxygen intrusion into the compressed gas. I doubt the stored volume would be significant. The wood is the storage medium. Thoughts?
+Clark Griswold You are correct in your statement. Propane in the cylinder is in a liquid form and there is a lot of run-time in a full tank but the woodgas cannot be compressed down to a liquid without the proper refinement process plus if there is ANY air in the mixture you have a possible bomb. The best thing I've seen is people compress it into a large balloon or into a tractor inner-tube. With the balloon it has enough pressure to push through a tube to run a small stove burner. With the tractor inner-tube you have to lay a piece of plywood on it and place weight on the plywood (Concrete blocks, Bags of sand etc) to force it out to a burner and it's a much safer method. The reality is woodgas is really a "on demand gas" that really needs to be used while it's being produced.
Thank you!
That, is so cool!! Great video.
It is a good good job .
Congrats nice work
I cant wait to see the efficiency reports compared to other options.
When you compressed 90psi in the grill tank, what was the run time or what amount of gas did you have compared to propane? Also, What compressor did you use? A regular air compressor gets pretty warm after a extended run time. Would that be a risk for gas ignition? I am concerned about an exploding compressor.
I looked on the victory gasworks site and only saw a 5k and 3k grid tie gasifier. It was nothing like yours. What is the size of yours?
Thanks for your response in advance.
This is an interesting experiment. I wonder of you could compress the woodgas into a large 300 or 400 gallon propane tank, allow the gas to sit and get very clean, and then run it into an electric generator. With the right setup, one could produce all the heat and all the electricity a farm needs. The electric generator could kick on as needed to supply supplemental power to solar/panels and battery bank. Heat extracted could go into the house, hot water an home in winter months.I know the big problem historically has been short engine life due to build of a dirt, ash and more in engines and engine life in a sustainable situation like this is very important.
It seems to me that using wood gas for cooking purposes isn't the most efficient idea. I mean you've started with combustible materials (ie wood) to create the wood gas, so wouldn't it be more efficient to just use the same fuel in a suitable wood burning stove (rocket stove, gasifier, etc) for your cooking needs?
Sometimes it is just nice to turn a knob and ... instant cooking. Cooking is the easiest thing to do on woodgas so why not get that down first and then head to engines, generators, on -demand water heaters, fischer-tropshe reactors etc.
engineer775 Practical Preppers I would also add that it seems that the wood gas is concentrated where there is a lot of lost heat in a wood stove. here in Chile we heat the house with wood and most of the heat goes up the stove pipe. Many people cook with wood as well and there is the same issue.
engineer775 Practical Preppers Not to mention,cooking on a wood stove in Summer is not a job I would want unless the kitchen was outdoors. Like the idea of storing gas and using as needed and life remains somewhat normal even in a grid down situation.
besides what others said, sometimes a wood fire is not an option. Camping and all the wood is wet or no wood to be had, outdoors during a burn ban during the dry season etc..
Sometimes you may just want something fast in a big hurry and not want to mess with building a fire. Maybe the morning coffee and an egg or two and then leave right away.
Having a useable amount of stored gas would be great for all the above
bwillan i wauld use a safe fridge compressor cose it generate plenty pressure
wow... great invention... can i ask the blueprint on how to make a compressing wood gas..
I've been wondering about this.
No regulator? Do you have your propane tank's valve fully open? Is there a way to extend run on your generator by regulating the gas flow? Just curious. I am getting ready to build a gasifier and have several out-of-date propane bottles on hand to use for storage of compressed wood gas. Interesting!
Have to put this in the category of: Totally Awesome!
Go BUCKS!!
Huhh, what did you say?? LOL Two questions: 1 Is there any danger that the compression could cause it to auto ignite like diesel (especially with a leaky head gasket on your compressor which would be susceptible to sucking air as you mentioned)? 2. If you ran the compressed gas through a heat exchanger, is there any possibility of getting it to a liquid state so that you could store more in your tank? What pressure would you need at, say, 72°F for the state change; the same or near to hydrogen? (I can't find my thermodynamics book anywhere...LOL)
If you get too much air in this it will go BOOM!!! Very dangerous especially in a propane tank. Ive had some pretty scary flash backs and this is without compression. When you compress and densify this gas and you get too much air the mix this will end very bad.
Very good
Great video thanks for posting it
You sir, are amazing!
I didn't see any comment on a earlier suggestion. Would a refrigerator compressor get u the quiet , high pressures ur looking for??
I think after you filter out the carbon monoxide you could be left with a decent gas that can be compressed quite well
the carbon monoxide is the flammable gas made from wood.
Very cool, in a hot kind of way..
you can use an cheap air compressor with motor series and add a cheap speed driver and use a oxygen sensor ( from car ) and PID contrôler (0-5v) input and 0-10v output or 0-5v (depending on your drive) to be able to compress a pure gas. :)
equipment can be purchased for less of $ 100 on ebay
Huh?
Very cool!
Great audio!
I wish you would consider doing a voice over rather than recording all the engine noises ! It would make it a lot easier for us people interested in your comments. thanks
I have heard that woodgas is an unstable gas that quickly decays into carbon powder and carbon dioxide. It will be interesting to see how it goes for you with the storage.
I sure would like to see any proof of that.
There is a lot of parroting this on the internet but I don;t have any proof. Just going to have to find out when and where things breakdown, change form, or become unusable.
Howdy.
Well it should be easy to prove. Just bottle some, let it sit for (time ? month ?) and see what happens. I don't know of any reason that the gas would separate. Very few gases separate from storage. Those are complex gasses held together with another ingredient. The gas combo gasification produces are much more simple. The thing I would be concerned about is container corrosion.
Barry Remainder hydrogen storage requires special tanks or it leaves and you have methane and co but i dont know what else could happen, for all intends and purpouses is should remain flamable just slow
Howdy
Tanks Dion for the input. And pressurized v.s. liquified are 2 different Boom Booms. I'd say us DIY'es are only in the pressurized category.
Gasification has a bit of a way to go, and its a shame because in general it's a low tech concept. But I think there is allot of $/usefullness to be made if we would comercialize home units (yep I know about GEK,, they have a great quality affordable product).
You should sell. A manual. On how to do this!
Awesome.
Seems like it would be a very useful and extremely cheap source of gas for running experiments where I need to purge all the oxygen. Would be useful for preventing oxide formation when melting zinc, actually.
One problem, your compressor drowns out everything you say. You're going to need a voice over track or explain in between the noisy bits
I'm interested in knowing more about using wood gas, but I couldn't hear a word you said.
Now this is truly outstanding. I did not realize it was safe to compress wood gas (or I am sure biodigestor methane gas) this way. Are there any warnings you can think of?
You used the magic word "safe". Compression causes heating and if it heats too much it goes boom. Anything over a couple of psi is potentially dangerous. Wood gas and methane systems are fairly safe due to the low pressures. A standard compressor isn't designed for this use. I've worked around a lot of compressors and most get too hot to touch. You may get away with it but then it's a hot day so the compressor gets a few degrees hotter then all they find are your empty shoes. I was thinking about compressing methane to 5 psi just to make a generator run better but even that much scares the heck out of me.
Probably mostly air because with a compressor sucking 30-60psi from wood gas generator. It will take maybe 2 seconds to empty all smoke then sucking air. Will need a large volume of gas in to the compressor
Scott I really liked this video. It makes wood gas more practical for me. I am a little worried about compression ignition in the compressor. How is this avoided?
Have you had woodgas pressurized in a tank long enough to find out that it breaks down chemically yet?.....H2+CO+time= H2O+C.....lol water and soot.....the higher the pressure the faster it happens....this was one of my few big disappointments in playing with gasifiers
Really? That sucks lol
What were your other disappointments?
Interesting! I've done academic research distilling in low (actually no) oxygen environments on wood (actually lignin). I'm curious if the compression, despite filtration, leads to any liquid products in your tank. Furthermore, I ponder whether or not creosotes or phenols may crystalize after cooling in the tank. That, of course, depends on how much oxidation occurs, but it has got me wondering.
I've always wondered how to set up my own compression system. I have long wanted to couple water electrolysis with compression of hydrogen gas.
Enginner775...how long will a small tank operate a generator? Excellent video! Thank You!
the wood gas we just made, the propane ..well that took a few thousand years to make:)
great job
Thank You!
That is so cool!
Nice Job !! How much did You get in the tank ?? How long will it run the generator and stove. ?? Most gases will ignite at a certain compression.. What PSI is it for wood gas ??
Not sure you'd get very much wood gas in a bottle that size. Wouldn't the wood gas always be in a gaseous state so the quantity in the bottle would be proportional to the pressure where as a normal bottle of cooking gas would be in liquid form in the bottle therefore a lot more stored gas.
Hey Scott, since woodgas is not compressing into a liquid at pressure like LP, whats your run time with a mid range load on a 90-120 psi tank of singas?
What is "singas"?....a really bad fart?
Great video! I wonder what psi it would take to liquefy wood gas? Also wonder if the propane cylinder was packed in dry ice while filling if one could achieve liquefied wood gas with a standard 120 psi home compressor.
How long does a tank of wood gas compared to propane. And also, is there a so called shelf life for this sitting in the tanks? I have heard it may break down after a while in the tanks and turn to a ash, not sure if that is a true statement or not. Very cool video
lots of comments about the danger of explosion. are those from theory, or have you witnessed the kaboom? has anyone had an accident? or successful/unsuccessful attempts at compressing wood gas? would love to hear your stories! thanks!
That is because inherently, a forced-air downdraft gassifier, the air is drawn through the system faster than the burn rate, which means that no matter how clean your woodgas is at the end of the process, it has unburnt oxygen in the mix. So you are compressing woodgas fuel and oxygen into a cylinder, it is just not a good idea, which is why for a very long time, gassifiers have been used as an "on-demand" method of producing syngas.
Using wood directly to say, cook dinner, is a tedious and wasteful affair. There is really no way of doing so inside of your home during warm months without making the inside of the home horribly hot. Of course, you could have a "detached kitchen/summer kitchen" for this, but cooking dinner would still be hot work.
Or, you could spend some time generating wood gas using free wood, then compress it (being sure the tank is properly purged before adding wood gas) for later use. Then, you can utilize it in a similar manner to propane. I suspect that it could be used as a replacement to propane if a burner configuration that is most efficient for wood gas is figured out and the propane appliances "converted". Probably would need to find a good way to regulate the wood gas pressure as well. If all this were figured out, in theory, you should be able to replace propane with wood gas. The flame-out safety protections on propane appliances should work for wood gas too (cut off gas supply if the flame goes out).
The big limiting factors to "converting to wood gas" would be obtaining wood gas (pretty much have to do it yourself with equipment you made yourself), ensuring safety (CO precautions), and sustainability. Theoretically, wood can be farmed to make it a renewable resource and it should be doable even if a large portion of the population "switched" over to wood gas instead of propane. Once technology advanced in the storage of wood gas, running cars and trucks on it would be pretty easy. No longer would you need an on-the-fly gas generator that takes forever to get going. You just turn on the gas supply, start up the engine, and go. When the wood gas is low, refill it either from your own storage tanks at home or at future wood gas stations.
Imagine, independance from oil companies when it comes to transportation. Imagine, a clean renewable energy source that can be used at any time of day or night regardless of weather. An energy source that is actually cheap to use. Making wood gas is quite simple. The hard part is filtering and storing it. If you can store it in a safe manner, you can transport it. If you can transport it, you can have wood gas refill stations. If you can have wood gas refill stations, you can run cars and trucks on wood gas in a similar manner to how we run them on gasoline and diesel. Instead of fields of corn, it will be massive forests of probably hybrid or genetically-modified trees bred/designed to grow quickly yet still yield a decent end-product.
Wood gas can be revolutionary. It can run gasoline engines. It can heat homes. It can be used to cook with. It can run generators (producing electricity). Pretty much anywhere propane or natural gas is utilized, it can be utilized. If the supply chain adapted properly, it could be a solid long-term renewable resource that is way better for the environment than our current fuels. It could literally put a huge dent in the climate change issue. With so much use of wood, naturally, companies and researchers will begin trying to find other ways to utilize wood. Maybe we could someday replace all our plastics with wood-based plastics.
