To start off, we did an indoor, test, as discussed earlier. Not much temperature increase was recorded, so we made some modifications so it would hold more heat. We opened the flaps and put a layer of mylar on top of the flaps. We cut holes in the mylar for the magnifying glasses and we put saran wrap on the top of the bowl so the bowl would hold more heat. We then tested the oven outside. We started at an initial temperature of 24 degrees Celsius.
After the test, there really was no temperature increase, but we think the results will be different once we actually go outside to test, because the sun will be coming from all directions, not just directly on top of the box. Data shown below.
Picture Before Test:
Picture After Test:
Our efficiency was obviously zero since the temperature was the exact same as started, so the input and output would be the same, and the equation would end up at zero.
