How To Make A Fuel Efficient Stove

These stoves are used in Send a Cow training in African countries as they use less wood and take smoke away from the cook. They are also a great idea for a design project for older pupils. You can make them over the period of a few days, depending on the weather, and with a bit of supervision they can be cooking their own food on it within a week! You could also set pupils the task of designing their own versions of the stove using various different materials.
