11. An Easy Alternative
Instead of gluing and bending all of that cardboard…
Simply get a reflector made for a car windshield and put the pot and bag inside

For a more permanent cooker, line hole with cement and paint with reflective paint
Remember to make the opening 400 square inches or 23 inch diameter
