1 Any dark coloured plastic bowl
2 Recyclable carton sheets
3 Black waterproof sheets
4 Inexpensive reflective louvre blades
5 Super glue
METHOD OF ASSEMBLAGE
Recyclable sheets of carton are trimmed to fit round the interior of the plastic bowl to act as insulation against heat loss. Back side of the tinted reflective louvre blades are further darkened by pasting black waterproof sheets to intensify reflectiveness of the mirrored surface. These blades are thereafter layered round the plastic bowl. The cooking pot is set on top of a little piece of wood at the centre of the bowl ensuring that sun rays act directly on the pot from all angles. Water pasteurization point can be achieved in less than 30 minutes. Most cereals car be cooked in less than one hour.
