My group's solar cooker actually started out as a box cooker. We made quite a bit of progress on it but ultimately changed our decision on what kind of cooker to use. We then brought in a big fresnel lens from an old TV and put together a frame for it. A fresnel lens can cook all by itself without having a solar cooker with it. I think the fresnel lens will cook decently but we will have to wait for it to be warm outside in order for the solar cookers to work. So far we have made very good progress and I think that this project will turn out really cool.
