with things I already had at home:
- reflective windshield shade
- large binder clip
- empty 5-gallon bucket
- empty smaller bucket
- clear pyrex bowl
- brown-tinted glass casserole dish with lid
(my "weeding bucket" - please excuse the dirt)
inside the 5-gallon bucket
to keep my clear pyrex bowl in place.
To test the temperature of my solar oven I filled my brown-tinted glass bowl with water about 2/3 full and covered it with the lid. The water temperature was 76.5 degrees F. when I began at 1:45 pm.
Here are my results:
1:45 pm - 76.5 degrees F. (began cooking)
2:45 pm - 120 degrees F. (intermittent cloud cover)
3:45 pm - 133.3 degrees F. (left for a soccer game)
6:30 pm - 106.5 degrees F. (area shaded when I returned)
Solar Cooker at Cantinawest has some great information if you'd like to learn more about solar cooking. Here's what they have to say about the best time to use a solar cooker:
"The most ideal time of the day for cooking in a solar cooker is between the hours of 9:00 AM and 4:00 PM, this being possible in the summer time when the sun is directly overhead for a longer period of the day.In the middle of Winter your "ideal" time will be reduced to between roughly 11:30 to 2:30 PM."They also have some solar cooker recipes on their website that sound good.
So, there you go. It was kinda fun. I'll try, try again -- getting an earlier start in the day next time. :)
