About three years ago I started investigating using the sun for outdoor cooking, mostly as an emergency source. I made my first solar oven using a Styrofoam cooler and aluminum foil. I placed a black cookie pan in the bottom and covered it with a piece of glass. It worked. I was able to bake potatoes and cook a roast in slow time.
I knew my primitive little cooker could be greatly improved upon, as it had some definite limitations. As I continued to gather information, I came across the Global Sun Oven. I was intrigued and eventually bought one. And I am glad I did! This little wonder has proven to be all it claims to be. I have had a blast cooking all kinds of things. Now it's to the point where if on a sunny day I don't have my oven out and cooking something, I feel like I am wasting the sun energy. That's the conservationist side of me.
