Rocket Lorena Two-Pothole Stove

Why to choose this solution?
The Rocket Lorena stove uses 50% less firewood compared to a three-stone cookstove. It cooks faster, since the fire is confined inside the stove, and produces less smoke. It is also easier to use than a three-stone fireplace, since the air inlet built into the stove eliminates the need to blow at the flames to keep the fire burning. It is safer to use, and it is affordable, since locally available materials are used. It also 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.
