Thank you for trying the instructable.

Purple was only for the contest. Do you have a picture?

You can not cook or purify water with 108 degrees. The street on a hot day can read 120 degrees. Add some reflectors and check the angle of the sun touching the cooking pot. To check the angles you can use a square piece of paper and line one edge up with the angle the sun comes in and the 90 degree angle it bounces off the reflector to find the right angle for your reflectors.

180C = 356F

If you make one please share it. I will do more testing for how large a pot and how much food could be cooked in it at one time. I have an 18 cup aluminum coffeepot and 2.5 gallon 19.5L aluminum 5 stacking pan set. I will paint them black and then test how much capacity and what heat they reach.

Thank you Alberta Auquaponics. I am going to try using the Rand vacuum solar tube in the Grande. I am glad to hear the regular Copenhagen Solar Cooker makes a good reflector for solar tubes.

How long does it take to reach 150F, the temperature water is pasteurized at?
