/diy/ - Do It Yourself

Glad to have helped.

The best advice is more reflector area the faster your food will cook.

You can also pre-heat an oven by lining it with brick or stone then heating it up for a while before putting your food in. The thermal mass will keep temps even when clouds pass by. When the sun goes away completely you can wrap the unit up and hold all that heat in for longer so it is still cooking your food. Paint the stones/bricks black with oven safe paint.

A black interior oven will raise the ambient air temps inside while a reflective interior oven will reflect some back out and a lot on the food or container you are cooking. Both had advantages. I prefer the black interior so no heat it lost.

Check out this style of box cooker and how you adjust the reflector panels. This is a modified kyoto solar cooker. It normally only has 1 reflector in the back. I edited 3 more in which is a design I plan on making next.
