This stove uses materials on hand and only requires minimal tooling. The design uses two auto tire rims (one of bigger diameter than the other) and a piece of sheet metal roofing. The design has been tested for weight loading and durability to heat but needs more testing. I intend only to pass this on to others who have testing and development capabilities. The operation is basic in that the sheet metal stand supports the larger diameter rim while creating access to slide the lower rim - with a fire built in it - underneath. The intent is to make this as simple and adaptable as possible with close to zero cost for material on only a chisel and hammer needed for tooling. Photos also show how the support stand was formed using the larger diameter tire rim as a form. The name "Rahisi" is swahili for "easy"
