Gasifier Stove

[jimlafazanidis]

how can I do the same gasifier stove with yours?

[tucsonpersonified]

Are you guys from Wisconsin or Cannuks?

[masterchrisd]

I think the Bush comment was a bit below the belt. Also, great bush comment, kick 'em where it hurts! As a footnote, excellent video, thank you for sharing

[crudeoilsystems]

what a nice stove

[ortsa123]

the bush comment really improved the video, good work!

[ultimatebanjo]

Agreed. The comment about Bush really degraded this video. 

[DaneStolthed]

Very efficient, now if we can only make it a bit more compact to fit in a car. Very informative video but did you have to go and make it political?

[woodnsteel19]

This "wood" have been more understandable without the piano music-a little country and western would be more appropriate-just cant stand intelligent conversation and properly pronounced yankee english....

[bluechevy98]

how much did it costs to build approximately?

[framed30]

Outstanding, jefferson co Pa?

[hanghoodiescum]

i found this boring / i just burn car tyres in my oil drum lol

[MrAnythingoutdoors]

If you download and read this publication it says for stationary use you should use a radiator, and an automated shaker or else you get bridging in the fire tube, none the less it pretty much fallows the plans I downloaded. the best part about this is the plans are still !free! from the FEMA web site me and a friend are in the process of doing a step by step build on this project google"FEMA stratified downdraft gasifier " if you have fire fox it wont let you download them : /

[Rhinoch8]

Carbon monoxide is not combustible, you swapped it with metahne :) CO is a residue from a non-complete combustion.

[calionstallion]

@Rhinoch8 if you think about what you said....CO is a residue from a non-complete combustion( of carbon). Doesn't that tell you there is some more combustion to be had? I don't know....I used to used to think the same thing you do....but I think i have becomed convinced that it should be combustible...

[Rhinoch8]

@calionstallion Yes, i've mistaken myself, you are right, CO is a Highly flammable gas!

[jonl326]

Where can I find the plans for it ?

[samoht1977]

..everyone keeps on thinking about "run a car on it, run a car on it"... I see no one ever got the REAL point of what a gasifier can do: please, leave that "I can run a car on it" alone! even if it could be done (and many people already did), that's not the point.

[stimulater7]

why dont you wait till winter for your next test ?

[xxx777aaa]

@sololamer i think INCREASED efficiency is the point here that they are demonstrating

[nonsequitur1979]

Wow, came across this video via reddit and you guys totally rock! I thought I knew everything about biomass heating methods and had never heard of this one. This is something I'd like to try in the future!

[Bristow42]

I have a question how long will be until the oil, gas, and elecity companies, use the government to put a stop to these systems, as they get no alot of money from these companies as revenue but shit loads. I even know how they will do it. Government safety regulation inspections, then comes registration fees, then out right tax. liittbug206 is right. It will go the way of the electric car.

[northernsun2]

I have a pellet stove and the pellet's gasifi real nice.

Around $5.00 for 40 lbs. goes a long way and is compact easy to store

[rwhendrix]

Good explaination. Thank you.

[prairiedf]

You are most welcome.

[wolf13011]

wow all u did was burned wood chips and u can run a gas engine on this i have i idea to use 1 of these with a modifided compresser to compress the gas so i can run a car on it for less than gasoline

[prairiedf]

They are probably working on it now... but if our societal system breaks down, this is one of the technologies that can be replicated easily by any competent mechanic. Plus it's fun to work on and has been a rallying point for our cadre of alternative thinkers.

-Greg

[morningstomper123]

@wolf13011 They had cars that ran on wood gas in world war two!

[DennisBBrown]

I have built my own Gasifier and it will be finished this weekend finall touches left . it will run a 350 chevy engine like your video had same trouble with moister.

[rustyman351]

I think the old man was going to add the yippy dog to the burn barrel until he saw the camera.

[litterbug206]

now the greedy obama kabul will tax it

[kurt9399]

@litterbug206 don't say that even if it is true lol you beat me to it

[mart2875]

could you tell me what did you use for a blower

[prairiedf]

We use a 12 volt automotive heater fan. It's kind of wimpy though, and we're looking for something about twice as powerful.

-Greg

[atomrocketcar]

@prairiedf how about 2 heater fan

i use heater fan as electric turbo on my car hehe

[VisionQuest2012]

This is a great way to run an electric generator when no gasoline or oil is available as a fuel.

[ppilleri]

We have an gasbed technology

burning prosess

if yoy want you can see this in my

channel

ppilleri channel

[MacKenzie]

I know you guys are from Wisconsin, but you sure sound Canadian. Good work on the unit - your voiceover also cleared up some things I didn't understand from the FEMA plans.

[prairiedf]

Glad this helped,

Greg

[livefree2011]

@MacKenzie they really do sound smart.... i mean Canadian. must be all the eh's they keep dropping lol

[fray1234jkl84032]

this will actually run a gas engine! no more $ 4 per gallon!

[EdgarInventor]

Great idea, and a money-saver!

Who can argue with those?

Thanks!

[EdgarInventor]

As for the Politics, really, who gives a hoot what Party Thomas Edison belonged to?

Skip the song-and-dance routine, as Archie Bunker said...

[sspence65]

The partisan politics comments were completely unnecessary to the goal of the video, and really detracted from the message. A real shame!

[xxx777aaa]

@sspence65 partisan politics in general are the real boogeymen here! @rain4fuel ... i dont think the "hippy" comment is necessary or accurate.

[livefree2011]

@xxx777aaa lmfao thats awsome

[erichertsens]

Thanks guys ;-). seems you had a good time building this

[renewablegossip]

Very cool contraption, nice explanation of how these things work but the boring music and lackluster voice over bored me to death.

[jmdist1]

MMCmedMD, double standard much? You say, "It'd be best if we could communicate our concerns and needs respectfully", but it's OK for you to say "greedy" because it is "well deserved", but you criticize "'hippy democrat global warming jerk" as not necessary.

How can you be so "intelligent" and not recognize that it's OK for you to break the "rules" as long as no one else does?

There are "well deserved" comments that could be made about other Presidents.

[benjamincheney]

Stopped watching at Bush comment. I would rather get my knowledge from an unbiased source.

[hondanovak]

@benjamincheney AKA, one that I agree with.

[flaviusicafsz]

please help me with advice to get flamable gas with my project GenCO in my video

[SteveWx123]

lladnarluap - if you don't trust people who say bush is greedy, who do you trust?

[lladnarluap]

Stopped watching at the lame Bush comment. If the author is that foolish/political/ect then I can't trust the rest.

[Rain4Fuel]

Decent video, but I don't think the Bush comment was necessary, or accurate. Bush didn't take the publication down, some hippy democrat global warming jerk did....

[MMCmedMD]

Thanks for the comment.

You're probably right the Bush comment is not necessary, but in my mind well deserved.

Your comment about 'hippy democrat global warming jerk' is also not necessary.

But alas, it is the way we humans are and this type of diatribe does little to remedy the crisis we face. It'd be best if we could communicate our concerns and needs respectfully and others would listen and respond with compassion and honesty.

peace,

Greg

[Rain4Fuel]

Decent video....but you ruined it with the political bullshit...makes you sound like a terd.

[jetsam50000]

Carbon monoxide is flamable?

[MMCmedMD]

Yes. The same thing that make CO poisonous, its 'infinity to bind' with hemoglobin, also make it want to burn and recombine with an oxygen molecule to form C02.

Best,

Greg

[peckiledorf]

3:26 ha ha ha ha

[MarkMcGrath]

Interesting video, but I could have lived without the political quip. Frankly I am interested in who or what stopped the publication.

Overall I like the video and I am glad you guys did such a good job.

[VilliVanilli]

I love you guys :0)

Keep posting those videos...

[honeybees1]

Yah sure eh.

[prairiedf]

Yu becha'der'den...

[normprogmail]

Tried the URL at the end of the video, and

didn't get through

[oldwhtguy]

Long live the greedy brute Bush!!!!

[miLLer3873]

It is great to see innovative, productive, and motivated Americans.

I have two questions. First, how is a gasifer any more efficient at producing power than just burning wood to heat water to power a turbine. Next, how would this power an internal combustion engine.

Thank You

[prairiedf]

Thanks! We enjoy working with this simple, but elegant technology. It has a lot of potential.

Katana's right with his comments. I might add that the two step gasification process uses very high temps (clean, efficient)in the first reaction. The 2nd reaction creates hydrogen and CO; a very high octane fuel, enabling use in an int comb eng (ICE).

We scrub the hot syn-gas in a cooling tower, then filter and feed into an ICE. Check out our other videos to see the ICE run and power a generator.

[emancoy]

hmm, this has a lot of potential

In wheat fields, and sugar cane fields, a lot plants that produce grain worldwide after harvest you have a pile of dried plant refuse. have they tried using them in this device?

[wherecanIfindutube]

I'll show my ignorance by saying that I didn't realize that Carbon Monoxide was flammable.

Since you obviously know your stuff, could I ask you why it doesn't burn while it's still in the combustion cycle of a automotive engine? What does Co turn into when it burns? Just plain old carbon and nothing else?

Maybe this question isn't a good one to answer here...That's completely fine.

Thanks!

[prairiedf]

Hi wherecanifindutube,

Good question.

I'm thinking it is the lack of oxygen again that retards complete combustion, though I'm just guessing.

In the case of syn-gas combustion, the CO is combined with oxygen to form CO2. The hydrogen is combined with oxygen to form H2O.

I've read a proper Stoichiometric ratio of syn-gas to air is 1:1.1 for high quality syn-gas.

Greg

[wherecanIfindutube]

Such an awesome video!

If you have the time would you be able to tell me what keeps the flame from backfeeding into the filter chamber (and beyond)?

Is it just the velocity of the gas as created by the fan?

Thank you!

[prairiedf]

Hi wherecanifindutube,

What keeps the flame from backfiring into the filter or gasifier is lack of oxygen. The syn-gas in stable until it mixes with oxygen, and then look-out.

This is what makes it so necessary to have complete closure in the system (no air leaks), because once oxygen is mixed with syn-gas it becomes explosive and can backfire or worse.

Greg

[emancoy]

can the gas produced in this fashion be stored in presurized tanks for later use?

please bear with me with the questions

[penguinistas]

I must agree with toadabc. I seems quite obvious that you hate President Bush and it chips away at your credibility. It makes you sound like the liberals who blame Bush for everything from sun spots to bad breath.

[prairiedf]

When Hurricane Katrina submerged the city of New Orleans, it laid bare huge gaps in the Bush administration's ability to lead. None is more jaw-dropping than the ineptitude shown by the federal agency created to respond to natural disasters.

Over its reign, the Bush administration has replaced competent leaders with people long on political connections but short on expertise. Chief among these were the (dis)appointments, was Lester Brown to head FEMA.

[penguinistas]

It is not in the jurisdiction of any President to usurp control from either the mayor of New Orleans or the Governor of Louisiana. Control of local government belongs to local officials and it is not reasonable for the President to pretend to know what is best for each of the tens of thousands of local governments scattered across America. At best, the federal government may assist but the authority and responsibility rest squarely upon local government alone. You are badly mistaken.

[toadabc]

how about more explanation of your equipment,and what you stuff actually does, and less Bush bashing and diagrams that doesn't look like your set up,eh?

[prairiedf]

As stated in the video, the hopper has been removed from the gasifier to allow easy access to the reactor chamber.

We used a 30 gallon drum instead of a garbage can for the gasifier plenum as detailed in the FEMA diagrams.

Please see comments above about Bush bashing.

[snogelplunderdop]

LOL, at 0:40 i thought he was going to put the dog in the chamber

[spark300c]

I wounder if can use hay for fuel in its raw form or do have make hay pellets. I very intersted in your experance and the cost of the fuel. I really this can be solution to our oil problems.

[superlesson]

where im from hay is much more expensive than wood, id love to trade some wood for hay

[WannaBEEfarmer]

This is the first Wood gas video that I have viewed.

Nice Video, thanks for the info.

Looks like a ANother project to add to my list.

Please take it easy on our president.

He is the best that the oil companys could buy.

Thanks

WBF

[carbons4]

Good job guys!

[Lapetitefumee]

Wow this looks like a red green show,,,

You guys, have you consider before playing with flamable gases:

to wear safety glasses,

put you dog down

get gloves,

and , hire a chemical engineer,,,,

ray

[prairiedf]

Hi Ray,

Thanks for the compliment on Red Green show similarity.

Good advice on the glasses, gloves too when necessary.

We know pretty much about the chemical processes that occurs in gasification and the issues/conditions surrounding this process, but any help is welcome.

Not sure what the dog did to offend you to want her put down.

Thanks,

Greg

[sabbadess]

Very nice work! I am working on a gasifier of my own and I am having trouble with the gas quality. How many CFM is your fan? I am using a 12 inch steel pipe and a 50cfm fan.

[cornjuggler]

nice gasifier. We also used the FEMA plans and the first attempt at lighting looked identical to yours. Our filter eventually caught on fire, so we abandoned the fema filter. Where did you get that great blower? And are all your joints brazed?

Cheers.

[prairiedf]

Thanks. Our filter caught fire too, after a very minor explosion inside the filter. It was caused by a small amount of air leaking into the filter, oxygenating the combustible gasses, and back-firing from the flame head into the filter. Quite exciting really! Once we sealed the head of the filter can, it eliminated the problem.

Our fan was used to inflate our double plastic skin greenhouse. They are available for around $50.

Our joints are all brazed, except the burn chamber to top plate.

[rugs0807]

Nice build on the plans from FEMA! Just wondering based on the size of the hopper in the plans and a flame size shown in your video how long will a hopper full of fuel last based on your experience? What type of blower and size are you using?

[Astrejim]

Can you compress and store the gas produced? Please let me know. This is amazing. Could you please send me your design?

[Hardy404]

Due to the large amount of incombustible gases in the wood gas, compressing and storing would cost way too much (electrical) energy for using it in a CNG vehicle for example. I thought of this myself but I let go of the idea as soon as I realised how much energy and storage space is needed .... :-(

[pitbike2006]

yea i have seen this on tv thay use 2 big tubs 1 bigger than the outher fill the big one with water and the smaller on upsaide down into the big one and drill 2 holes on the top so the air can come out and the tub ill sink and then start filling with the gas and the tub will rise and it will be stared and when it runns out it will sink back down so u can have a guess on how mutch u have left if you need drawings tell me and i will email you ASH

[mrhjoker21]

hey this is really cool...i made a gassifier out of an old paint can, soup can and a small fan. it works great. but would most likely work better if i could find some wood pellets....could you suggest such a place......thanks

[prairiedf]

Hi,

We get ours at the local farm supply store, Farm and Fleet. They're also available at our local feed mill. They are becoming more and more available.

[mrhjoker21]

cool,, thanks

[angelodommy]

Awesome!

[TiczonFamily]

why not use the WATER bubbler after that filter to avoid corrosion in the engine.

[prairiedf]

We have thought to change filters, but it all takes time and energy. If we do a liquid filter, we'd probably use oil as the liquid, as it has an affinity for tar, which is the major contaminant in our wood-gas.

Most of the water seems to accumulate in the water traps and base of the wood chip filter.

Cheers,

Greg

[thenox44]

Hello...

I have a very strange question: could you tell me what is the music in the background as this vid not only looks but sounds very nice ;-)

Keep up good work!

Cheers

[glen196969]

Great work guys. Question. How important is wood type ??poplar, cedar, walnut?? I have a design in the works that uses the ICE's exhuast heat to keep the wood smoldering but not combusting for more gases at a high temp. The exhaust also provides pressure. The second chamber (filter) has a valve at the bottom to release the unwanted heavy gases. The lighter gases will exit the top to the carb. Thnx

[prairiedf]

Hi Glen,

Thanks!

Any wood will work; some contain more caloric content and will burn longer and produce more gas. Most any biomass can be made to flow and fed into the stove. Grains work well too. Proper moisture content (20% or less) is necessary to not retard desired mass/energy conversions.

Interesting idea to preheat and turbo-charge with the exhaust from an ICE.

We turbo charged our stove with a shop-vac. The cozy 12 inch flame turned into a roaring four foot torch. Really amazing!

Greg

[0cujo0]

Great Job! Awesome gasifer stove!

I've seen the old Pre-WW2 stoves and have lots of questions about this advanced model.

The filter medium used(dried wood?), do you still have to drain the filter unit often? Like the old gasifiers?

[prairiedf]

Thanks!

We did use chipped wood for the filter medium. It is working reasonably well, though I don't have much to compare it against.

We do seem to need liquid traps to catch excess moisture. This could be due to using not quite dry enough fuel.

[0cujo0]

The old WW2 filters used crumbled up cork pieces to trap water in the filter. Maybe an inch deep along the bottom to start? Place a small screen over that, and add the wood.

[ehrichweiss]

Any chance you could post links to the PDFs, etc. that you got your information from? I'm incredibly interested in this idea. Thanks

[Hardy404]

Search for: fema wood gas generator gengas

It's the first link.

Kind regards and happy welding,

Hardy

[MrfixitRick]

This is inspiring! Perhaps a Tesla Turbine would be a proper engine to run from this.

[prairiedf]

We sure thought it was. And lots of fun too. And Practical.

Using a Tesla Turbine is a very interesting thought. I'm not extremely well educated about about them, but have considered building one in the past. They don't look all that complex or difficult to build.

Any thoughts?

[MrfixitRick]

Tesla wanted to run cars, trains, and airplanes with his turbine. Most of his turbines ran on steam, but he had gas-powered designs that didn't need a carburetor, just a valvular conduit with no moving parts. Try googling "frank germano tesla turbine" for detailed info.

[cbb137]

I can't wait to see this hooked up to an engine. Good work guys.

[prairiedf]

Thanks!

We're working on finding an old pickup now. We're going to hook it up to am old lawnmower soon and work out the kinks. I'll try and film this and put it up in the future.

Our group had thought to use the wood-gas powered pickup in parades and county fairs to draw attention to local, sustainable energy systems. Maybe power a small bus at fairs or at local downtowns.

[ontheearthproduction]

nice work greg, you're now a videographer AND an inventor! -k
