... Or maybe I should say de-foiled.
We tried to cook in our home-made solar box cooker again yesterday, and our foil-covered reflector kept blowing down. It must have happened about 5 times. I'm not sure how many hours of sunlight we lost, but the end result was our old favourite - uncooked rice.
At the moment only one side of the reflector is held up by wire. I'm going to put a wire holder thingy on the other side as well - and hopefully that should do the trick.
In the meantime, We'll haul out our panel cooker from Solar Cookers International and get that going.
