Modified BYU Solar Funnel Cooker - 01

*Read description for detailed info* My version of a BYU Solar Funnel cooker. Uses a collapsible chair for a base. Plenty of mistakes. I just put the cooker together fast and shot video. ;) I said 7" diameter for the cutout, actually meant radius..etc etc. :) The water in the pot got up to 180F after 2 hours. These cookers can do crockpot temperatures as long as you have good sunshine. Even on bare pots. If the pot were in the 2 gal glass cookie jar I normally use, the air temp inside would have been 300F. I've cooked potatoes before, just laying them inside the large glass jar.
