fire7side: I built one somewhat similar. I've heated water with it so far. I find I have to throw larger chunks of wood in it, like 1/2 inch diameter by 2 inches long, once the tinder burns, easily cut with a very small saw like on a folding knife. I'm looking forward to trying it for camping. I built a pot holder out of another can that compresses inside the first one. Thanks for the vid and let us know how it works in the wild.
kitsurubami: lol your jb weld is on fire
LeopoldUlysees: Very cool! It make char coal, char cloth, and cook your grub. A versatile, inexpensive, and easily-made device.
SurprizedDaily: Thanks much...look forward to checking those out...you made one yet? Thanks agin.....shalom, SD
tjwiltube: Thanks, guys! Good info.
FYI, in addition to a gasification stove making charcoal, you can also use it to make charcloth -- the stage one tinder used when making an old fashion flint-and-steel camp fire. I did that with my little, experimental stove. YouTube won't let me lionk to it here; but it's titled "Wood Gas Charcloth," if you want to see it on my channel, tjwiltube.
christo930: Here it is.
He has 2 videos on doing this, one with a fan and one without. The one without the fan works just as good. He also demonstrates how much less smoke the fire produces with a flue.
christo930: Yeah. Look for a video about making home-made charcoal. The guy is doing it outside in front of a red truck if I recall correctly. He's burning wood for different reasons, but it looks like it will work the same.
SurprizedDaily: Have you seen any on here with flue added? Curious as to how? Where and the rest of the particulars as to your thoughts? Fixing to make one here....look forward to any clarifications you can suggest..thanks, SD
christo930: Add a flue to it, maybe half the height of the can and put several holes in it. You will get almost NO smoke AND be left with high quality charcoal when you are done. The flue makes a HUGE difference and you will entirely burn all of the hydrocarbons and tar and whatnot and be left with nearly pure carbon charcoal at the end.
frogsoda: After watching several videos on "woodgas" stoves I finally understand the process. It's a downdraft stove with larger holes on the outside can to draw in fresh air which causes the downdraft in the smaller can, bringing the gases in between the two cans to be ignited in the top holes of the smaller can. Ha. Simple. Ben Franklin would be proud.
1acroyear1: The main advantage of this is it's lighter than a rocket stove and you don't need to carry fuel for it like an alcohol stove. It burns twigs. After burning the gas you end up with hot coals, so it's almost like burning the same wood twice.
I don't think this makes for a very good hiking stove, tho. It has to be quart-can sized to bring two cups of water to a rolling boil and there's a limit to how much fuel you can feed it in one burning. Two smaller ones might be an option.
kafene: The reason I want one of these is because I don't need to pack fuel (unless I'm in the sand dunes). If I have to pack fuel (like an alcohol stove), might as well take my propane & hiking/camp stove, which is very small, quick, and efficient. The cons with these stoves is the soot your have to deal with.
freeriding666: Can someone tell me the advantage of this, over either a "beer can" alcohol stove or a rocket stove?
I suppose it needs no gas, since it extracts the oxygen from the wood to use it as burning gas, if I'm correct. So is it then more efficient than a rocket stove?
Noone: Sorry, but you are wrong. The gasifier starves the heated wood of oxygen by combusting the air before it reaches the wood being pyrolized. It then re-introduces oxygen at the top, which allows the gas to combust.
1973Saved: Wow, some great ideas here plus a great video & design. I wonder if an inverted stainless steel metal seive/strainer would work as the metal cage fhqwgads2 mentioned.
Mitch Ashdown: My simillar gs camp stove lasted four years of quite frequent use, and being left out in the rain quite a bit. It's actually the final stage of the burn when it switches to burning off the carcoal that burns the can the most. While it is still gasifying the wood isn't very hot.
tjwiltube: @henchman99942...Good point on the JB Weld. It doesn't hold up to the high temperature. This was a quick, experimental build, and JB Weld was what I had on hand. It served its purpose in the moment. I disagree regarding your assertion that nothing is being gassed. Sorry, your statement is incorrect. ALL wood fires involve pyrolysis. The trick is to divert the wood's volatiles to a desired location prior to oxidizing it. In this case, most of the volatiles were diverted to the gas jets
tjwiltube: @1acroyear1...The music is from a 1960's era, 33 1/3 rpm album titled "Dreams." Artists included the talented Brecker Brothers on brass, and Billy Cobham Jr. on percussion.
looking4thepast09: great music love it
1acroyear1: I just want to know the name/ artist of that song.
