Solar Oven Year End

The final test of the solar oven for this year was performed yesterday, Saturday, October 22, 2022. Trials will begin again next year, in early summer. The highest oven temperature reached yesterday was about 142° Fahrenheit. That is more than 20° below the temperature from the last test (see video).

The trials take place on a roof. Sun at this time of the year moves below the tops of surrounding buildings, shading the oven for time periods that prevent it from reaching high temperatures. I mentioned in the last video that I would adjust the copper flashing, which I did. When I saw the copper flashing reflecting brightly opposite the aluminum foil on its outer surface, I assumed that one side was more polished than the other and that I missed the difference when I placed it in the oven. It was not necessary; however, as later, I found that both sides of the flashing were the same.

The reflectors would not stay on due to the wind. I will have a remedy for this by next year. I am planning to add quarter-inch plywood around the styrofoam. Swivel brackets can then be attached to the wood without destroying the styrofoam.

The building materials I used for the oven are listed below. Feel free to contact me if you have any questions about what I did. Let me know what your results are if you decide to try this yourself.
