As such, sufficient fuel for cooking tasks can be gathered in less time, without the benefit of tools, and ideally without the destruction of forested areas.īecause these qualities improve local air quality, and discourage deforestation, the rocket stove has attracted the attention of a number of Appropriate Technology concerns, which have deployed it in numerous third-world locales (notably, the Rwandan refugee camps). Furthermore, the design of the stove requires small diameter lengths of wood, which can generally be satisfied with small branches. Rocket Stoves operates roughly twice as efficiently, and substantially more cleanly, than the open fire cooking methods still used in many areas of the world. ![]() Baking is done inside the inner drum-in a sealed compartment within the chimney, above the firebox. The outer drum is split open to create an insulated chimney space between the two drums and to allow for a doorway. Rocket stoves used in conjunction with hayboxes can save enormous amounts of fuel, cooking complete meals while using very few resources.Ī related design, the Rocket Bread Oven, is constructed using two 55 gallon drums, one inside the other. The low-mass stove body and insulated chimney ensure that the heat goes into the cooking pot, not into the stove. The pieces of wood or other material burn at their tips, increasing combustion efficiency, creating a very hot fire, and eliminating smoke. Rocket Stoves use branches, twigs, small wood scraps, or just about any small combustible material. A skirt around the pot will help hold heat in, increasing the efficiency. Cooking is done on top of a short insulated chimney. These are low-mass stoves designed to burn small pieces of wood very efficiently. It is easy to construct, with low-cost materials. This design uses more bricks, but because the metal sheet is flatter than the cooking surface in the 1st design and the heat is more concentrated, we think it will end up being better to use.The Rocket Stove, a popular variety of improved combustion stoves, is an integral part of the Integrated Cooking Method. In this case we will be welding the exhaust pipe onto the edge of cooking surface instead of at the bottom, so as not too lose excess heat. In the second design we decided to use the metal bricks as the primary insulation, a smaller metal cylinder for concentrated heat in the centre and a seperate metal sheet as the cooking surface. Metal tray and metal grid (we welded scrap metal sheets to make the ashtray and small metal rods to make the grid). Metal Barrel for cooking surface (its too late for us now, but I strongly suggest sanding off the paint before using it),ģ metal pipes- 2 for the L tube and 1 for the exhaust pipe (some welding will need to be done here), ![]() Soil, sand, straw, cow manure and clay to make your mud mortar, and if you’re ambitious your bricks too,Īdobe bricks (if you’re not feeling that ambitious), So far, its looking like Design 2 is going to work better. We built two stoves of the 1st design, and 1 of the 2nd design. Just ensure, that if you build a bigger one its under a roof for rain protection.īrianna, our mega talented intern, made two rocket stove designs for the farm as an experiment to see which is better in terms of efficiency, practicality and cost and for educational purposes. So, how can we build kitchen stoves that promote community cooking, are super efficient, use less heat, provide more heat and don’t leave us stinking of smoke? Our awesome permaculture interns had the answer…”Lets build a Rocket Stove!!!” A Rocket Stove is mega efficient, really fun to build, it doesn’t cost the earth, can be built out of recycled materials and is a great activity for kids – especially if you’re planning to use and make your own mud mixture to build with like we did! (Tell them you’re building a rocket anything and they’ll be in!) If you already have a stove, consider building one of these for your outdoor space, bbqs, or a portable, down-sized one for camping. So needless to say, the cooking stove is an important part of our farm. For us its also a gathering place for sharing ideas, socialising and where our produce will be transformed into delicious, off-the-farm meals. Its where family, friends and visitors spend quality time. A kitchen space is probably one of the most important spaces for a home and even more so for a community space.
