Talk: Solar cooking frequently-asked questions

Revision as of 06:19, 1 May 2007

what's the difference between all solar cooker.

Food temperatures

I've just changed the sentence that said no food can go above 100 C as it's not strictly true. Pure water boils at 100 C but as soom as you put something in it it boils at a very slightly higher temperature, for example jam can boil at 104 C . There is some food that can get much hotter if it contains sufficiently little water. Toffee for the extreme example needs a temperature of 150 C / 300 F. Obviously at altitude these boiling temperatures drop. 84.51.146.100 09:12, 15 April 2007 (UTC)

That is quite right. Thanks for that edit. I might add that I lived at at 9200 ft (2800 m) for awhile. At that elevation, water boils at 90°C. Beans are difficult to cook in an unpressurized container. Walter Siegmund 18:16, 15 April 2007 (UTC)

If a major source of heat lost is the window then it would be wise to use double windows? Like seperated by a half inch air gap. Oh just made my first solar box cooker (just need to get the window). I may try it with one window first then a second one. I guess it will also reduce light input so it may have trade offs.
