Rocket Lorena Two Pot-hole Stove

Why to choose this solution?
It uses 50% less firewood compared to a three stone cookstove, cooks faster since the fire is confined in the stove and less smoke is produced. It is also easy to use since it has an air in let therefore there is no need to blow at the flames to keep the fire burning as there is with three stone fire place. It is also safer to use. It is affordable since locally available materials are used and retains heat for a long time after cooking.
Savings per day or production:
According to Mrs. Mayanja Eva (a user trained by JEEP), the rocket Lorena stove uses 4-6 pieces of firewood for one to have a complete meal cooked. It saves energy and time because it has two potholes compared to the traditional (open) 3-stone fire stove. The Rocket Lorena stove is safe because, when it is made, an insulator i.e. dry grass is used, which creates air pockets. Hence, when cooking this prevents heat loss.
