Not that I ever have tried to myself, but my youngest son did. Two eggs, sunny side up, using cardboard covered with tin foil.
Recently, after supplying old windows to a local reader for her cold frame project, she sent me a photo of her own version of a solar oven.
She said:
“My first attempt at cooking rice in the solar oven - I left it for 7 hours in (March) sunshine and the cavity between the tyre and the glass reached 80 degrees F which wasn't that hot... The water inside the jar was hot though and the rice smelt like cooking rice does, so I'm not totally discouraged. I'll keep you posted ;)”
I thought it seemed pretty ingenious.

And after looking at another solar oven at a link she provided I decided to build my own.
How hard could it be to heat up a few leftovers on my back deck while I'm sipping a cold home brew?
I have leftover windows and cedar too from the never-ending reno. All I need is some type of insulating material. I’ll figure it out this week or next, once the last of my birdhouses is nailed together.
I”ll keep you posted too:)

Do you, or would you, use a solar oven once in awhile?
