06-20-2013 Generator running on small dead branches and sticks.

The generator is running on yard waste material such as small tree branches and sticks. I took this test one step further by getting an exact weight measurement of the wood to be used as fuel so that I can get a good idea of the generator run-time vs how much wood by weight was consumed. The results were great. This is going to be one of my last generator test videos with the gasifier but I will release two more videos before I move on to a new project.I will make a video showing the gasifier mounted onto the trailer as a final build followed with a gasifier "How to" construction video.

[@braxtonhaze820]

flash you have the most interesting in depth practical learning videos I have ever seen! you have a dynamite personality. keep the videos coming

[@flash001USA]

Hi Braxton thanks for the views and the kind words.

[@cobra64th21]

This has to be one of the coolest things I have seen. Looks much more cost efficient than solar panels. This system would be great in cold climates where you are burning wood for heat.

[@CNCmachiningisfun]

As I am not on the grid, I am rely on a gasifier for my electric power. For many years, I used gasoline for power generation. At times of extra heavy power use, this could cost as much as $100 per week! Ouch!! Seeing the fuel bill suddenly drop to near zero totally blows me away :) Your super deep charcoal bed is surely a winner, as I think this is a key factor in a successful system. You have covered all of the bases very well indeed, and you really should be proud of your acheivements :) .

[@flash001USA]

Patrick thanks for the vote of confidence. This build is pretty close and I do plan on doing a video on how I built this. I'm waiting on some steel from the machine shop that I'm having fabricated for my final build before I can make a how to video so be a little patient with me. There are places to get hot water off of the unit starting with the output pipe right on top of the gasifier. You could either wrap copper tubing or make a sleeve to steal heat from it so yeah, try out some ideas!

[@Prepmor308]

Thanks for the update.Can't speak for others but I do appreciate your willingness to share what you learned.Folks may not realize how this shortens the learning curve.That's what pisses me off about people who make negative comments.Many put out the failures and mistakes right along with the successes here on YT.I appreciate any ones efforts because it moves info forward.It's up to people to glean the good from the bad as they work on their own stuff.Looking forward to your next project...

[@twalsh05]

Pretty exciting. I reckon I'm not the only one who is really keen to try your build!

[@flash001USA]

It's kind of like rolling an octagon tire down the road. Roll it enough and the corners will wear down and become a smooth round tire. I can honestly say that I put a lot of thought and work into this project but I'm really glad that I did now because this is something that may pay off to have in the future.

[@flash001USA]

Gary I'm using the drums with the removable lid and the lock ring. It works good and the heat has not damaged the rubber ring. My lids have a white rubber that is really hard and apparently it can handle the heat. If you have doubts, just use red RTV cement. You can get it from Advanced auto in the big plastic tubes made for a caulking gun for around $10-$12 bucks. Don't buy the tiny tubes or you will pay too much. With a bit of luck I will be uploading the second "How to" video this evening.

[@impowerfree]

well your doing one heck of a job and I am really enjoying it. I was looking for my "next project". think I found it. Thanks again!!

[@Snarky79]

Impressive for absolutely sure! Many years ago my father died and left me some old nautical magazines. I recall seeing an ad for a small boat engine that bragged that it could run on gasoline, kerosine or alcohol-whatever youv'e got. Ingenuity -always impressive. I see that in spades with your rig too. Hats off, thumbs up!! Boats used this gas too but diesel won out.

[@flash001USA]

I've been asked this before. The gasifier is an extremely efficient burner and because of that it doesn't get as hot as you may think. People think these are like a wood stove but the truth is they don't put off a bunch of heat. They do produce heat but not like you would imagine. If I placed this inside of my house I would freeze. If you try to harvest heat to make hot water, you will drop the internal temperature and either start to produce tar or gum up the heat exchanger which would be bad.

[@YukonCornelius72]

As for a next project, you should check into making an anaerobic digester to compliment the gasifier. You could then also make methane to burn from types of wet, moist kitchen scrap, lawn clippings, and feces. Not as complicated as gasifiers, but still fun to create a viable alternate fuel from unwanted waste.

[@flash001USA]

That's a damned good observation and you are the first person out of ALL of my blogs that has brought up this point. Woodgas is not like other fuels. It can contain tar if you are not careful and the tar will literally gum up the valves to where they will not move and even if you are cracking the tar the carbon soot's in the gas can collect in the engine and cause the same issues. Gasoline on the other hand does contain carbon (Hydrocarbons) and over time they too will wear an engine out. Cont:

[@norrisb0616]

Man you're an inspiration to me, you really give me something to think about. Its amazing of how many ways you can make fuel !!!!!................

[@flash001USA]

Thanks. It's really exciting to see an engine run on smoke-gas from wood.

[@TranquilKaos]

Thank God :D I have been getting it in the ear for having a half finished 'piece of scrap' sitting it the yard... I thought it was a bit harsh to call it scrap, but it has no function (other than experimenting.... and nowhere near stable with my improvised design) Many thanks again :)

[@flash001USA]

escapadeable Thanks for the reply. This setup was built for a small engine but it could be geared up for a larger engine but you would have to resize the air nozzle and the fire cone. I will be uploading a video explaining this build very soon. Thanks.

[@ImMADasAMeatAxe]

bloody hell thats extremely efficient running your own power station looks an economically sound plan

[@flash001USA]

So far this gasifier seems to be very stable plus there wasn't any special metal fabrication that needed to be carried out so that was another reason for a straight forward simpler build too.

[@cns688]

You mention using sealed barrels to store the wood in, I suggest that you drill some holes in the barrels to allow air through the wood as it will help the wood to dry out even better. Great Video. Thank you.

[@flash001USA]

Hey thanks for the reply. The wood I mentioned is so bone dry that it can be packed into a sealed container. This is emergency use only wood that I want to keep rain, rats and bees from getting inside of so that's why I mentioned that these were sealed containers. If this was green or even semi-green wood it would not work but being bone dry seasoned wood it should be OK...

[@stompbuilds5416]

Nice system. I'm impressed you can maintain 107 volts with such a heavy load. Thanks for sharing.

[@flash001USA]

Yeah, save the charcoal (biochar) because it is perfect for starting the gasifier up with. This is what I used to fire the gasifier up in this video. It gives you a very hot and clean start. If you have extra biochar left over you can just spread it into your yard or even use it to line the bottom of flower pots with.

[@flash001USA]

I was actually able to get out and cut some steel today. It has rained every single day on me here. I am going to have a change of plans and break this video up into a handful of small videos. I plan on starting with the construction of fire cone with the first video and if this weekend behaves weather wise I should get a video out this weekend.

[@flash001USA]

The inverter idea is the correct way to go and I'm set up for that if I need to take that route. Most stuff will handle 50 or 60 hz with no issues and analog power supplies definitely will. My only concern is the inrush current of a compressor motor on something like a refrigerator or a small window AC unit but then as long as the RPM's are good on the generator it should be OK.

[@TheRchunter57]

I am very grateful for your efforts in sharing your education gained by thoughtful, planned improvements, changes and the like. I'm just waiting for your build video and it's off to the races! One thought you might have encountered doing your research is what about using the imbert to run a turbine to the generator head instead of a combustion engine? less moving parts, lower decibels?, less maintenance. Run across anything like that? Keep up the good work,,,, I'm going to go play my banjer

[@mazdalorean]

I feel your pain, I work full time too . I've had projects take as long as 5 years to complete. I do love to take advantage of the motivation that you get with starting a new project. I hit the ground running on my gassifier build.By the way , thanks again for posting these how to vids. They have become very valuable to my design phase . I've probably watched each one 5 times just to make double sure I didn't miss anything .

[@flash001USA]

Hey thanks for the reply. Yeah, time is worth it's weight in gold so I'm just waiting on a break to complete this build.

[@flash001USA]

The inverted V does have one big plus and that is the inverted V already has the inverted bell built right into it. The reason I went with the build I have is because love it or hate it, the small FEMA runs extremely stable even though it's a tar maker. I went after the best of both worlds where I used a semi-FEMA approach but with a cone instead of the straight fire tube. I also used an air nozzle too so this build is in between a downdraft FEMA and the Imbert design Cont:

[@wannabeepro]

what about capturing the heat given off by the engine?... And when I posed the earlier Question about steam engines, and giving more thought, I don't believe the steam is more efficient in regards to fuel, but may be simpler only, I am going to research that as well... Thanks for the vid. it is very detailed and you obviously spent a lot of time on it...Good work.

[@flash001USA]

Yeah, this has a single nozzle but I just modified it with 3 nozzles offset at 120 Deg from each other with the same kind of setup that I did with the one I built with 5 nozzles. This system works great but I do have a concern that the nozzle hanging over the center of the ember bed may cause a bridging issue. I have not seen that but I wanted to try a new configuration just as a backup design. I have also changed up the tri-filters so that they breathe easier. I'll be doing a "How to" vid soon.

[@flash001USA]

You mentioned the inner jacket and I know that it isn't advisable to use giant wood hoppers unless you are set up with a capture jacket. If the hopper is external or exposed to the outside air they will allow any moisture to collect on the sides and run down into the ember bed but I've been looking for that and I'm just not seeing condensation in the hopper. Look at my videos when I open the lid. The sides of the hopper are bone dry.

[@雷神索爾-y8f]

Yes! I come from Taiwan Province, Taipei I really like your video tar filter

[@flash001USA]

Another good way to look at this would to look at a 100 watt light bulb. It gets so hot that you cannot hold onto it while it's running but it cools down very fast once you turn it off. The energy in the gasifier is not free so it's a trade-off yes you are producing heat but the gas that's being produced takes away from the heat that is used as fuel.

[@flash001USA]

Hey man I appreciate that. The deep ember bed just made sense to me after I started to look at the stratified downdraft gasifier stuff. I'm still refining things but I am happy so far. Since the generator does not handle a load as well on woodgas without losing RPM I will probably use an inverter and use the generator to keep the batteries topped off with the exception of plugging directly into the generator with a 5oo Watt washing machine for washing clothes. Some AC stuff won't be critical.

[@dougshade118]

i want your plans. to build this unit. you have had the best luck of anyone i ahve seen. i am inpressed. verry nice job

[@flash001USA]

Thanks Doug. It's not perfect but it does work well as long as you pay attention to everything while the gasifier is running. If you look at some of my later videos I actually break the gasifier down and show how I built this one.

[@flash001USA]

You may be able to use a box around the engine with a small blower as long as the engine is not leaking any exhaust. This is why I said that you could use a heat exchanger with the exhaust as an option. In the end, the first step is to get a functional gasifier but design it so that it can grow with new mods as you come up with ideas.

[@2185justme]

Great Job !!! Your work Is Priceless!!! Keep it up.. Look forward too your final breakdown video! THANKS AGAIN

[@TecKnowFreak]

I take it now you get why i say i always have the extra filters not for that i need them really but i have always only used just what ever wood i can get never used pellets. That extra moisture in the normal wood one can get that is almost always there and only thing to do is let the extra water get filtered out and if you ever get only wood that is say after a rain its wetter then normal with having extra filters they can take up more of that water in the wood. Great vid great show!

[@flash001USA]

KZbin user Tecknowfreak pretty much says the same thing you are saying. When the wood is at it's correct water content, you do see some white in the flare which is hydrogen. It's a fine line to have the wood at the right water moisture content. The stuff I ran on these last was pushing the envelope on moisture content but I still had a pretty steady and clean run so I was happy with that.

[@flash001USA]

Tim stay tuned. I am getting ready to make a video explaining the build. The weather has been my only hold back.

[@phil36135]

Are they any plans availible for your design ? I would love to build one. Yours is the best Ive seen.

[@flash001USA]

Reach out to me through www.miniwoodgas.com. Just contact me through the contact web host button on the homepage.

[@flash001USA]

Yeah, this blows my mind everytime I see the engine run off of wood. I think the gas is cleaner because I am cooling it all the way down. I didn't see any tars in the jar or the tank this time so that was good. I had a hard time with this gasifier being stable until I made one change. I got rid of the inverted bell and replaced it with a piece of straight tube. There is another thing that I did with this build too. My ember bed is 9 inches deep. from the bottom of the air nozzle.

[@psmola101]

Great videos. One of the concerns I would have with the generator RPM is running a small motor such as a refrigerator, because the frequency as well as the voltage are critical to running a motor. Motors (and most electronics are designed to run on 60Hz) If the generator RPM is off, so is the frequency. The solution to this is to use an inverter generator. Although they are more expensive, they will put out clean 60Hz power and when bogged down will only lower the voltage, not the frequency.

[@CNCmachiningisfun]

Absolutely brilliant, as always. You have created a system that you should be very proud of :) . Your filters are doing a great job of cleaning the gas, so your engine will surely enjoy a very long lifespan. My Imbert is pretty good, but yours is better! I wonder if you get the same set of mixed feelings as I do: Even after all this successful engine runtime, and also becoming confident that you can start and run your engine, do you find yourself still being amazed that it's even possible?

[@larryvturner]

Excellent work and I too want to thank you for your thorough work and sharing your knowledge with us newbees. The Imbert is so much better than the FEMA and after looking at the additional work of making a retort, I have decided to stay with a system (wood chunks) like you just demonstrated. Looking forward to the final build and thanks again for your effort.

[@flash001USA]

imperialmen I am going to make a "how to" video because I have already made improvements on this gasifier and the filter setup since this video. My only holdup is a metal fabrication guy that is supposed to be making me a few fire cones. I hand rolled the fire cones in this gasifier and it wasn't easy but it paid off and now I know how to really fine tune this so be a little patient with me. As to the volume of gas, I'm not sure. One more thing, what is a Lister?

[@flash001USA]

Sir David. I just finished up the first part of the "How to" video yesterday and it will cover your question. I will try to have it uploaded this evening and if not I will have it uploaded in the next day or so.

[@flash001USA]

OK, look it like this...This is accumulated heat. The pipes and the gasifier do get hot but as soon as you start extracting heat from the system it will cool down very fast. Keep in mind that there are no flames inside of the gasifier. There are only embers.On my build the ember bed would be the physical size of a medium size grape fruit or a softball so in reality there isn't a lot of a heat producer there. You would need a large gasifier that could run a truck to take advantage of the heat.

[@flash001USA]

Yeah, you are right about the cylinder head. I'm concerned about the valves and bearings but I'm probably OK as long as I keep up the oil changes.

[@MultiOutdoorman]

Have you looked into bottling the woodgas with a compressor, so it can be stored up? I believe you need at least 1500psi ...or so i read!

[@flash001USA]

That was my concern. I was worried about rust inside the engine. Thanks for that tip.

[@flash001USA]

xoxoXoieoxox Thanks for that tip. The hopper is pretty much dry when I open it and I don't have any sweat running down the inside of it plus this is a small internal hopper that is heated by the gas surrounding it. I think my fix will be to make sure that the wood has a lower moisture content. I have ran dryer stuff like the pellets with no moisture issues so I'll try to cure some wood and keep it from the outdoor elements to see how that works.

[@flash001USA]

Hi 1944yo I am currently working on a "How to" video right now so stay tuned. Thanks.

[@mazdalorean]

I can't wait to see this on the trailer. Nice job.

[@flash001USA]

That makes two of us. I've been doing nothing but working a day job followed with playing music professionally 4 sometimes 5 nights a week non-stop so I'm just waiting to catch a break where I can finish up the gasifier job.

[@nasanction]

Hi Flash! I'm a victim of the Gasser Virus. I just had a meet and greet yesterday with Mada94fxr (Mark) Fantastic guy! Very helpful getting me started on my build. We will be using your design of the gassifier, and a few changes by Mark. I'm a bit overwhelmed right now, but I'm getting the grasp of it. ;) I wanted to say thanks for your efforts in this field! Maybe someday Mark and I can come do a meet and greet at your place. We had a blast talking about the gasifier and almost everything that pertains to power generation. It was a whirlwind, and I feel brain stuffed. lol Great stuff!

[@flash001USA]

Hey thanks for the feedback. Yeah Mark has a really good setup. The good thing about all these people out here that are doing this is they've taken the basic idea that I started off with and added their own ideas to it along with making improvements so that we can keep this open source for everybody. The most important thing is not to rush the build. The concept is pretty simple and the learning curve is pretty simple but it's one of those things you have to Tinker with an experiment with to find what works for you. Good luck with it and we all look forward to seeing you put a video out in the future when you get yours up and running.

[@Angus_McGyver]

For comparison, how much gasoline would your generator burn per hour? Also, I was planning on a solar dryer for my wood.

[@mikereynolds8804]

I am sorry, Sir Flash! I should have subscribed to your channel years ago! Quality Stuff!

[@flash001USA]

Yes it could be done. There others out there that are piping the exhaust into a wood dryer to dry their wood just in case it is too damp for the gasifier.

[@flash001USA]

I ran out of text but what I wanted to say was I will be doing a "How to" video very soon and this will hopefully answer a lot of questions for people wanting to try this for themselves. On the tri-filters, I went from 4 inch diameter pipe to 6 inch diameter pipe and this will get rid of a lot of back pressure on the engine intake. As soon as it quits raining here, I'll test everything so that everybody can see what I have done before I make the "How to" video.

[@flash001USA]

Thanks. It's been a long road full of learning experiences but I finally got it.

[@flash001USA]

Cont: Keep in mind that the heat that is produced is being used to break down the unconsumed wood so very little of the heat is wasted. Go check out my last video (Video 4) You will see me take measurements and this will tell you just how cool this is running. The reasoning for cooling the gas down with all of the pipe is to condense the wood gas for a more robust gas plus cool gas filters quite nicely compared to warm wood gas. I hope this helps you.

[@Jm4steam]

Would it be viable to take the exhaust from the generator....go to expansion etc, to use residual heat for water heating or even steam?

[@YukonCornelius72]

This project was great! I learned a lot. For some other great gasifier info, you should check out All Power Labs. They have some great info and videos and all open source plans. They have a set up where they use the heat if the gas from the gasifier to a pre-warmer hopper to help drive out moisture from the wood before it even goes into the gasifier.

[@joshuawood6046]

At about 5:30, we’re those sparks from the gasified itself or from something touching it?

[@flash001USA]

I have not thought about using a turbine but it sounds interesting. Finding a turbine probably would be a bit more difficult than finding a small engine unless you were to build a custom turbine.

[@flash001USA]

Danny it would be a big waste to convert woodgas over to run a generator then to reconvert it back over to run electric heaters. You would be better off either running wood stoves of propane for the heat and use the generators for lights and other household electronics but to answer your question you would need a big gasifier running a large generator to be running electric heaters.

[@garyshackelford4571]

Flash, first of all thanx for putting data out there for us, im about through the cone build and really anxious for next vid. I have a buddy who works for a oil compay, (Ironic), that will give me some 55 gallon drums, didnt know whether to get couple with the removable lid with band or just solid drum. One better than the other? Again thanx for all you have put into this..

[@flash001USA]

You're right, it does but you still need to be careful not to cool the engine too much. The older battleships used to run large diesel engines and instead of using the conventional radiator setup like you would expect in a big rig they took advantage of the ocean water to cool the engines. They realized that if they cooled the engines too much that the efficiency decreased so they had to regulate the engine temperatures better. Cont:

[@2185justme]

Hows the material list or construction vid coming.. Used ur lopper idea only mounting it to a 55 gallon barrel, this way I can lop and drop in stead of always picking up pieces. Need something else to do , 2 ,55 gallon barrels full of material with no place to go .. Thanks for sharing your ideas.

[@nlo114]

Hi Flash, excellent videos. I have watched just about everybody else's efforts but this is the tops. I'd like to build this, using a water-cooled engine. The gasifier pre-heat burner could be used to warm the engine water before start-up. Exhaust and cylinder heat exchangers push low-grade heat to the house, the power generated goes in an immersion to raise the final temp. It seems constant load is best and easiest to manage. I'm impressed by your efforts, keep it up!

[@flash001USA]

Thanks. I'm no guru on this stuff but I can chicken scratch and tinker with the "best of the best" so this project was a labor of love and curiosity thing for me.Your idea sounds pretty cool coo. I'll be looking forward to a future video from your channel on this. Good luck.

[@flash001USA]

I didn't mean to write a book on it either. My bad. Woodgas is environmentally friendly so a catalytic converter wouldn't be much help since you are dealing with soot and some tars that might be in the woodgas and that is what you need to filter out.

[@concreteart101]

Love the content new to the gasafier going to build one or two awesome 👍👍

[@flash001USA]

Thanks for the feedback. This build has been polished and refined since this video was made. kzbin.info/www/bejne/rmfRgHyEoNlpe9U

[@ryanwalton986]

5.5 lbs of wood contain about 14 kW hours of energy. You were able to get about 1 kW hour out, so your efficiency is 1/13 or about 7.7%. That's not bad for a system built at home running on only sticks and branches. Nice job!

[@flash001USA]

The good thing about the fuel I use is I can just go out into the woods and pick it up from the ground.

[@flash001USA]

The only reason that I noticed the smell was because I noticed the lack of a sweet gasoline smell. The smell I'm describing is not that pronounced unless you stand near the engine. I also noticed that even before the engine cranks, there is zero smoke vapor or water vapors coming from the exhaust as I crank it but even the invisible gas has an odor and unless I was to really process it that will always be there.

[@flash001USA]

You could make a heat exchanger to harvest the heat from the exhaust. If you try to harvest the heat from the engine itself you may rob some power from the engine if it cooled too much but harvesting the heat from the exhaust would not hurt the engine performance.

[@braxtonhaze820]

flash have you ever done a video on waste oil burner as fuel for gasifier?

[@TheScrappingJeahaha]

Really cool stuff !!! What you can do agains damages from the moisture is to let the engine run after the woodgas 5-10 minutes of gas , then theres no water in the cylinder or something else i think , everything should be right then ;D

[@flash001USA]

I just watched one of their new videos. Great info!

[@MultiOutdoorman]

I've seen people install a wrapped copper coil as a heat exchanger and extract the energy to heat water as well as produce gas... ENGINEER 775 does some interesting stuff too!

[@flash001USA]

Someone made a comment to me that you can see the learning curve I went through just from watching my first video up till now. I always got the flare but it took me a lot of messing around with this to get a consistent blue flare.

[@impowerfree]

Ok Sir Flash, I have built what I can from what I've been able to watch and learn. Do you have an ETA on the burn chamber/air nozzle final video? not pushing but curious and excited. you have done a great amount of trial and error and saved a lot of headaches for a lot of people. THANK YOU!!

[@flash001USA]

Honestly I don't know. It isn't fuel friendly and that I do remember but both gasoline and propane will allow the generator to run at it's full output but then again, I can accept some power loss with the trade-off being me using sticks and broken branches as a fuel.

[@flash001USA]

How much cupric oxide do you need to accomplish the task and how long will it last before it's depleted?

[@flash001USA]

I actually found some of that info and most of this stuff has been translated very well.

[@flash001USA]

Paul I'm absolutely interested in that idea. Is the material readily available and if so is it expensive and is it environmentally friendly?

[@fitterlo]

u have it down now, great work.

[@flash001USA]

Do you mean adding a drain valve on the filters?

[@catfish500mark9]

Do you remember which video shows how you built this burn chamber?Man I have got to build one of these.☆☆☆☆☆

[@flash001USA]

I had the same ideas you are thinking of when I first started this. Imagine this. The fire cone is around 6 inches in diameter and it reduces down to 3 inches. The length of the cone is 9 inches. The ember bed that is doing the work is only 3 to 4 inches deep so in reality you have a red hot bed of embers the size of a softball. This should give you an idea of just how small the actual heat source is. :Cont

[@impowerfree]

excellent work!! it appears in this video that your air supply has changed from a multi port system entering the bottom of the burn chamber to a tube going down inside the hopper. is this correct?

[@shaknitboss]

Have you thought about adding in some air conditioner dryers or make another filter and fill it with silica to remove any water that is present

[@flash001USA]

This is what the expansion tank is for. It would take a pretty big filter full of silica to remove all of the water but you do have a good idea. For a smaller setup like this it's not as critical but on large industrial systems they use every trick in the book to dry the gas.

[@mickdannii2315]

mate your a bloody ledgend :) thank you for educating all us newby s n cant wait till i see the how to on your final cut :) ps how much difference between the lambert or your system and a down draft system again thank cheers ya aussie mate mick

[@garykernstock354]

I really enjoy your video's, you do a great job. Couple questions. 1 do you take off the fan when you hook up to the generator. and 2, I saw a man on youtube that explained that since the woodgas or syngas burns cleaner he slows down the timing on the engine which match's up with the clean burn of the hydrogen and oxygen in the woodgas and that will take care of the loss in power problem.

[@flash001USA]

Gary the fan is only used to start the gasifier up. I do not adjust or touch the engine timing and with the bigger filters that you can see on my last video where I was testing the new design out you can see the system as a whole breathes easier and the engine runs stronger now but it does not have the same punch as gasoline but then again, a bag of sticks are much cheaper than a gallon of gasoline so the trade-off is beyond worth it.

[@pohickngrits]

Hello. I like the way you present your videos. Thanks. If you've got time for a question, why does practical gasification and combustion occur in the same container? The classic middle school science demonstration puts toothpicks in a test tube with a flame outside of the test tube (s. chadphil). I can't argue with success. But I'm wondering if there'd be less mess w/o mixing the fire and gas together? I don't know. Does the question make sense?

[@flash001USA]

The middle school science demonstration analogy is 100% correct. Your question kind of makes sense but so far this can only work one way where the raw fuel sits on the ember bed and breaks down due to the extreme heat that gives you that "middle school science demonstration" effect but on a much larger scale. I hope that answered your question.

[@pohickngrits]

flash001USA Extreme-est heat--yes that makes sense. I'm grateful for your responding to our armchair inquiries. I live in a tight-pack, suburban townhouse w/o time or resource to change a headlamp in my truck--it ain't that bad, but you know. That's my story. I'm sticking to it. I enjoy your videos and hope to live long enough to enjoy retirement and give it go myself. Gotta get back to work. Thanks again.

keep in mind that u do want a little moisture in the wood B\C this is were the H2CO2 picks up the hydrogen molecule its a reaction between H2O & C0 they combine at high temps to create the gas so bone dry wood wont work as well as seasoned wood will =3-

Hi Flash, have thought about storing the gas into tanks

[@garyshackelford4571]

Thanx for reply Flash.

Catalytic converters reduces harmful emissions of hydrocarbons, carbon monoxide and nitrogen oxides into the atmosphere. The catalytic convertor works by converting gases into water vapour and less harmful gases but I don't think it would clean the raw woodgas up correctly. Believe it or not, the woodgas exhaust does not add a thing to the carbon footprint. The exhaust from the woodgas from an engine is equal to naturally decaying wood on the ground so it's environmentally friendly.

grid feed here in australia is 10 cents per kilowatt hour,, big enough generator,, unlimited source of wood,, this could be a fun game of make the meter spin backwards

Hi Buddy. Have you viewed "MRTESLONIAN" vids ? He is into all this woodgas stuff too! I wish i had the land / space to have a go at building something like this ! I live in the UK and we're not so good with acreage. Keep em coming cos its really interesting. I've watched most of your work. Great ingenuity.
