        I guess it is now.

        As long as someone is interested, I'll explain what I did:

        I already had one solar oven, which I made for crock pot meals. It cooks brown rice and veggies in an hour.

        I made a solar oven using 3" tall pieces of drywall for the walls and scrap wood for the floor. Then I scrapped some window glass and put it on top. I painted the interior black with tempura. I also painted bricks black and set them on the floor. I used the turntable off of an old barstool so I can turn it to take full advantage of the sun. It gets to 180 deg F by noon and 220 deg F by 3 pm.

        I am putting together DIY panels. So I got a bunch of 6"x6" solar cells, strung them together in series, and made a bunch of 16 cell panels with a sandwiche of a glass front, a layer of EVA, a layer of the cells, a layer of EVA, and plastic backs. The various ways that I've heard of for heating the EVA to laminate the sandwiche were insufferable because it is summer. I made the solar oven just to fit the solar panels. I put the panel in by noon, and lay a piece of hardibacker (painted black) on top of it and all layers are laminated together by 6. The thermometer says the temp drops to 150 deg F when I put it in and is close to 200 again by 3 pm.

        I use broken mirror pieces when it gets a little cloudy or hazy to keep the heat on. Otherwise, I just turn it a little every hour. The oven is tilted, and so the air bubbles work their way out. The flat weight on top is just to keep the plastic back from wrinkling in the heat. I tried putting the bricks on top, but that didn't allow the air bubbles to work their way out.

        Then I started using chips to run scrapped electric motors. I cut some "propellors" out of plastic jugs and glued one to a small motor's shaft. So now it sits in the oven and blows the air around. When I go to open the door, I turn the panel over to shut off the fan.

        I make small panels because I am not strong enough to handle the bigger panels.

          That's a very expanded explanation Thanks.
