Step 4The solar cooker.
It can be a funnel cooker, a panel cooker, or something like what i made here. Tracking is not perfect with this simple tracker but good enough for these types of cookers and a whole lot better than no tracking at all!
I used a lazy susan. I had some waste thin plywood, I bent it to the curve of the susan, and cut some off the 2 ends from the middle to the edge at the bottom so it leans forward a bit.
Then I used flour paste to stick the kitchen foil to it. This sends the light down to the mason jar (which is covered by a plastic bag to slow heat loss.
I had to join a 4 inch diameter cylinder at the bottom of the lazy susan to act as a gear.
4 inches because the clock turns at 30 degrees per hour but the sun moves at only 15 degrees per hour. The coffee container was the perfect size!
