Building my first solar oven

I celebrated the Fall Equinox by building and testing my first solar oven. One of those projects I’d been thinking about all summer and the waning sun motivated.

It was a project made of scraps. I had the plywood box from a WSU Auction. The 1/2 inch reflective insulation was left from building garage doors on Peterson Barn Guesthouse. It took a little practice to recover my (ca. High School) glass cutting skills, but they allowed me to re-use a piece of glass from a defunct cold frame.

The lid still needs a reflective treatment and a means to prop it at an angle to reflect into the box. As it was, I got 3 cups of beans and water to 135F from 11AM till 3PM. Needed another hour simmering on the stove to finish cooking them.

I needed to rotate the box to track the sun. To reduce that need, I want to think about wings that will bounce light from the side — ultimately having a bit of a light funnel.
