One of the earliest sources of energy utilized by man was his own muscle. Food, water and other loads were borne by the arm, head, shoulder or back. Latter, animals such as dogs, donkeys, oxen and mules, etc were used as beasts of burden. Next to that was the discovery of fire, probably obtained by striking rocks together. The fire was used to cook food, keep warm, clear bush, preserve farm produce, harden pottery for bowls and produce tools from metals. Subsequently, other sources of energy such as solar energy, wind energy, electrical energy, nuclear energy and fossil fuels were discovered (Sutkhame, 1990). It is a well-known fact that more than half of the people in third world countries depend heavily on bio-fuels such as charcoal, fuel wood, crop residues and dung to meet their energy requirement for cooking. The main objective is to make cooking with fire easier, safer, faster, and can add to the beauty of the kitchen and in reducing emissions. A good stove is quicker to start, needs little tending, and can meet the specific needs of a cook that contribute to global climate change

4. INTRODUCTION
 The costs of using firewood in traditional ways are growing every day. Fuel
wood is the primary source of energy for households in developing
countries. It is used mainly for domestic cooking
 It is for this regard the Multi-purpose cooker stove is designed and
implemented

10. CONCLUSION & RECOMMENDATION
 The quality and thickness of the insulating material need a review with a view
to using a cheaper and more efficient insulator.
Heat shields should be used below the charcoal grate so as to increase the heat
transfer efficiency, if the air preheating effect would not be sacrificed.
The distance between the charcoal bed and the bottom of the pot should be
reduced in such a way that the combustion efficiency and heat transfer efficiency
can be maximized
The stove is recommended for small and medium scale agro based enterprises
whose business entails processing both for local consumption and export, as well
as other processing jobs and cooking.
