Solar ovens. I am on a learning journey. I am trying to figure out how to build a solar oven, only I am trying to do it without spending more than $10 on it. I would like to figure out how to do it with stuff I have around the house. In a crisis, you can’t go to lowes and buy a bunch of wood and stuff, you have to work with what you have. I have not been able to sustain a “cooking” temp. yet, but I have gotten it up to 220′ for a few minutes. The sun then went behind a cloud and it dropped to 160′. I will let you know and post photos as I experment. I can use any ideas that you have. Thanks.
