I saw a similar one on the web made of 4X4 box tube. I didn't have any tube so I drew one up for 11G plate. Tis one does not "rocket" but has a VERY respectable draft and concentrated heat. It is very efficient with small twigs and such. I was quite happy with it. Fun little project! One guy says he puts a twig stove, matches and emergency food and water in a 5Gal bucket with a lid. He has several of these for his pickup, house and out buildings. Not a bad idea!

The rocket stove concept is been around for along time. The use of the stove is also fairly common in 3rd world countries. I used the concept on many of my Insulated BBQ smokers. There are some that will say they invented the rocket stove but that's stretching the truth.

Thank you very much..i am building a wood stove fr my house right now and a friend ask if I would build him a rocket stove and was going to haft to draw one up..lol..seriously life is weird at times.

To get the most out of it, meaning the most BTUs out with the smallest amount of fuel burned the insulation is very important.
Just read thru the PDF I posted and it will make sense.

Hi Steve, I agree that in the smallest stoves insulation is a big factor. I don't think this stove falls into that category. It burns very efficiently for it's size with just a hint of that rocket tearing sound and actually provides a bit of radiant heat once it is really cooking. It could be used as a small heater in a well ventilated shelter such as a lean-to or bough shelter, snow cave or such. I think the biggest advantage is that it provides a hot concentrated heat from an almost inexhaustible twig and scrap wood source. No fuel bottles, sterno or propane required. I understand that rocket stoves are used all over the world for cooking and heating in areas like Madagascar where they have to squeeze every BTU possible from the remaining biomass..............RK

I know a lot of these or designed & built with weight in mind for campers. But I thought that perhaps some would like to know how to get the MAX BTUs out of this style stove. Actually the way you constructed it is the most popular design.
They have a guy that has come up with a boiler package to run a micro steam turbine to charge phones and provide laptop power. . . These are also popular in certain parks where propane is not allowed.
Thanks for posting, it reminded me that I never got one built.
This twig stove is cool, I would like to make one for camping. Short stove story: My neighbor built a nice airtight stove for his house. When his insurance agent was over he saw the stove and asked about it. Long story short, neighbor had to pull it out! No UL certification on the stove meant it invalidated his home owners insurance. Scary stuff. Just wanted to mention it as a precautionary thing for those building stoves that will be mounted in their homes.

I love little rocket stoves. Very popular in the 3rd world. I have a family friend that I make them for and he ships them back to his family in Sierra Leone, Africa. I make mine with small 25 lbs and 30 lbs refrigerant tanks, 3" square tubing, and insulate with perlite.

I'd like to see a couple of pics of one of those. Used refrigerant tanks get tossed to the scrap pile where I work.
