Stoves

There are a number of stoves that can either be bought or made and the choice would depend on the availabliity of resources – fuel e.g. wood, sticks, paper etc as well as access to material – bricks, tins, metal containers etc. The simplest form of cooker cuold be a tin can using Energy Balls for fuel.

ROCKET STOVE

Low-tech is the new high-tech, and the best example of the low-tech revolution is the miraculous rocket stove–a stove that makes it possible to cook with small twigs–no logs needed! Best of all rocket stoves are easy to build.

The rocket stove was originally developed for cooking purposes where a relatively small amount of heat is required on a continuous basis, applied to the bottom and sides of a cooking pot. Stoves can be constructed from brick, recycled steel cans, steel sheet metal, or can be purchased.

Rocket stoves consist of a L shaped tube, at the bottom of which you place your wood. The Rocket elbow can be made from different materials such as sand/clay (Lorena), pumice/concrete, heavy steel pipe, 430 stainless steel or refractory ceramic.

The chimney effect creates a highly efficient, largely smoke-free burn. There's no need to cut down a tree to cook your dinner–all you need is a few small branches or twigs.

The Rocket Stove is a variety of wood-burning cooking stove. It is easy to construct, with low-cost materials. These are low-mass stoves designed to burn small pieces of wood very efficiently. Cooking is done on top of a short insulated chimney. The stoves are typically constructed out of trash: tin cans, old stovepipes, etc. A skirt around the pot will help hold heat in, increasing the efficiency.

Rocket Stoves use branches, twigs, small wood scraps, or just about any small combustible material. The pieces of wood or other material burn at their tips, increasing combustion efficiency, creating a very hot fire, and eliminating smoke. The low-mass stove body and insulated chimney ensure that the heat goes into the cooking pot, not into the stove. The exhaust gases then pass out of the building via the chimney. Rocket stoves used in conjunction with wonderboxes can save enormous amounts of fuel, cooking complete meals while using very few resources.

Tin Rocket Stoves

 

These rocket stoves were made using large and small tin cans. The inside of the stove has an L shaped chimney which is surrounded by sand to insulate and focus the heat upwards to the stove top. The cracks in the tin are stuffed with clay so the sand wont leak out. A flat piece of tin laying in the bottom of the fire hole allows air to circulate from under the sticks and keeps the fire going hot. The tools used to make these were a tin snip, screwdriver and sheet metal screws, and pliers

  • Jolene:

    Out of what consists the enery balls?
    The energy balls are made from newspaper and candle wax or wood shavings.

    • Hello Jolene,
      I have only just seen your enquiry of May 2012. Apologies for that. The Energy Balls, also known as Fire Balls, are made of newspaper and grated candlewax or sawdust. There is a special way to fold the balls and compress them by squeezing them tightly in your hand. The balls then are put in the sun for 5 days and are ready for use.
