Rhisiart Gwilym: Ingenious little stove, but it's not a Rocket: No insulation; riser too short for the cross-sectional area. Right proportions and insulation are essential to get the full Rocket effect developed over many years of both theoretical study and practical field-work by Larry Winiarski, Ianto Evans and their many collaborators. Don't re-invent the wheel. Study their work. Try this first: http://www.aprovecho.org/lab/index.php
Also see this PDF for the basic, well-evolved design principles of a genuine Rocket, which will work at much higher temperatures (because of the essential insulation), with complete clean fuel burn, and therefore great fuel economy:
And no, don't use galvanised steel anywhere near high heat. Or burn the zinc off first, whilst standing well upwind.
WSNmin: No one has ever seen God, but the one and only Son, who is himself God and is in closest relationship with the Father, has made Him known - JESUS CHRIST IS LORD
Gen Eric: If you put the lid back on, it will reach boiling temperature much quicker.
wow sly: its good, i like it :D
Mike Jones: some type of insulation placed around the barrel would burn more the wood gasses and get less smoke and need less fuel.....peace my friend
amackey313: looks like you stole that knife from Mad MAx. Dig the vid
dascooker: modified meat cleaver! Cool. One could survive down on the shores of the mighty Hudson river banks with these items for a nights stay. I like it.
mockingmoose: Are you a hobo ?
vgg huu: Very nice stove. For urban survival knowing how to turn some of the infinite amount of junk laying around into a stove in a good skill to know.
justclickgo: I made one out of the galvanized metal and it killed two of my friends... Thanks.
envirosponsible: Yeah man! That's an excellent idea. Keeps the current set up light and utilizes what can be found. Thanks for sharing that.
Kakashi101sensi: For a true rocket effect you have to have the stove insulated to reach the high heat inside that instantly heats/drys/ and com bust the material in its "fire" area. I would suggest to keep that design and just kick/pack some dirt around that. And call it as you have a portable/micro rocket stove, just add "substrate", which could be dirt, sand, etc....
Devon Blacksmith: Insulation is not necessary for a clean burn, check out the DK rocket stoves Quick to heat up, clean burn and quick to cool
KenshinBattousai374: Be very careful heating that duct material. WHen the galvanizing heats up high enough, it will give of fumes that can easily give you metal fever. Which is lethal.
Jim Bronaugh: Nice design. I don't know if it is a rocket stove, but it is a very nice closed table top stove that could be used in any park. A little twig burner like that would take care of most camp cooking and be easy to fuel.

Miss Columbia was crowned the Miss universe Frankly speaking: Jaqueline is SUPER CUNT this year. Used to like her, but she's a trouble maker. I know she has that slow kid and all, but that's no excuse for her to behave like an ass hole.
