Last sunday we had some fun with my father in law’s solar oven project. He built it for his math class, he will challenge his students to create as close to perfect parabolic dishes as possible surface them with something reflective (in this case outdoor chromed vinyl) and see what tempreature the focus gets too.
In this case we estimated that the tempreature of the foil pan got to about 190 degrees using an oven thermometer. We had hot dogs and also tried an egg, which took considerably longer to cook, but it cooked. And we ate it 🙂
