Several years back I made a cooker very similar to this. All I needed was a sheet of plywood, an old used tire, old newspaper to act as insulation inside the tire, and aluminum foil to go on top of the paper on the inside of the tire to add a reflective surface. As I recall I also put aluminum foil on the plywood under the tire as well, but unlike in this older post, I did not put it on top of the the tire sidewall. The glass I used was just an old window, still in the frame. I don't know how important it was but I used a cast iron Dutch oven figuring how well cast iron was at distributing heat. You have to move it every once in awhile to make sure it's lined up as best possible to the Sun, and I also used some old mirrors and just set them on the edge of it and angled them to reflect sunlight directly into the cooking chamber, and I just used poles driven in the ground to lean up against the mirrors. And of course these had to be changed as the Sun moved as well to keep the maximum amount of sunlight going into the cooking chamber. I will say that one of the best baked potatoes I've ever made was in that suncooker. Also cooked some pretty good chicken leg quarters. I didn't have much else cuz I didn't have much money, and was kind of trying not to starve at the time.
Bad memories.
But anyway it was part of my survival strategy, and I'm sharing this, because I think it's important to know and remember, that you don't always have to have a lot of money to spend to buy something pre-made, when it's possible sometimes to build what you need in a difficult situation out of scrap. Necessity being the mother of invention, ect.
Thank you for your time.
