There have been two “controlled” tests run on the solar cooker. Additionally, there have been 2 meals cooked in the solar cooker. Both meals were beans and were thoroughly cooked. (The data from these test are still being analyzed more thoroughly).

The maximum recorded temperature was 91 degrees Celsius; however; the temperature sensor was placed between the pot and the cob insulation. This would not indicate the temperature of the actual food being cooked.
