FUTEK is a box type solar cooker with eight reflectors that can produce temperatures of around 120°C on clear sunny days. It costs US$110 and includes four cooking pots. This model of Solar Cooker can also accommodate a 3 lt. Pressure cooker. The organization has developed cookers with 3 pots ($75), and cookers with 4 reflectors and 1 pot ($60). They have also developed another very low cost cooker, though not good looking but quite effective and light weight, costing only $45.
These cookers can be fabricated at home with some hand tools and locally available materials. They have found that these cookers can be used for pasteurizing water. Even on a partly cloudy or hazy day one can use these for pasteurizing water for a number of times.
