Cooking Stoves:

Traditional cooking fire                             (Top of page)

Many persons around the world cook over open fires, supporting their pots on three stones.  Maybe 3 billion people, half the world's population, cook using wood, charcoal, animal dung, or crop residues.

 
       

Why?:  Cooking stoves can save money, and time, and health!                            (Top of page)

The cooking experience can be improved by using a stove.  Lots of different designs are possible, made of lots of different materials:  the simplest, built of clay or mud, can be made by almost anyone, anywhere, and at almost no cost.  More elaborate designs made of metal can cost $20 or more, or can be imported from other countries for a similar price.

The advantages of cooking stoves include:

  • They burn maybe 50% less fuel, because they burn efficiently, and heat is concentrated under the pan.
  • Saves money if users buy fuel, or saves time collecting and carrying firewood.
  • They produce less smoke.
  • The smoke can be channelled up a chimney out of the kitchen.
  • Less smoke means less damage to lungs by breathing in smoke, and less damage to eyes.
  • Cooking times are greatly reduced, and the fire is more easily controllable.
  • Less fuel results in fewer trees being cut down which is much better for the environment.
  • Stable stoves result in fewer accidents.

Other ways to improve cooking efficiency and safety include:

  • Lids on the cooking pots.
  • Pre-soaking cereals and beans before cooking.
  • Insulation around the fire.
  • Shield around the pot, to force the heat close to the pot.
  •  An open chimney above the fire.

Environmental Impact:                           (Top of page)

It has been said that an average Malawian burns 120 trees a year cooking over an open fire, which can be reduced to 40 when using a fuel efficient stove.  Thus every stove produced can save 80 trees per year.  (This seems an optimistic estimate!)

In a small project in Uganda I have seen over 200 stoves produced by one potter in a first year of production, even whilst his main business was making pots.  If each stove saves 80 trees these 200 potentially save 16,000 trees.  (Even if these estimates are optimistic, even if the saving is only half, or a quarter it is still very significant.)

Imagine those benefits multiplied thousands of times across Africa, Asia, South America and elsewhere in the world?  What a wonderful saving to the people who use the stoves, and to the world climate in reduced pollution, and reduced deforestation.

Refugee camps have been known to consume 1 million kilograms of firewood per week.

 

Built-in or Portable?:                           (Top of page)

Stoves can be built-in at the location where they are to be used, or can be portable.  Built in stoves are probably safer and better in use, and can be more easily given a chimney, but have to be built on site by someone who knows how.  Portable stoves can be made at any location and then transported to a market or shop for sale, and then to home by the purchaser so it is easier to create a business manufacturing portable stoves.
