Dear Dieter
This is an excellent point: >One of many reasons for coupling solar and wood is that there are additional applications for comfortable use of the solar cooker: baking, bottling, preparing juice or jam and other products which cannot be prepared with stoves which work on high temperatures. The SK14 and similar solar cookers do not surpass 200 °C. There are so many sectors of the stove market that we should prepare appliances for and it is good to be reminded now and then that the local use to which a stove might be put could be very much unlike cooking. In Indonesia people routinely have 4 or 5 different cooking devices which they use when they are preparing that food, just like I do at home. Each one can be called a stove, but they are specialised, really, and do something things really well that he others do not. Cecil Cook in his investigations last year into the use of fuels and stove found people in Central Java (where is about to be launched an improved stove rollout) were very adept at picking particular fuels for certain purposes, as well as using multiple stoves during any month. Come fuels were used only for high power and some for keeping a fire just going for a long time. The use or solar cookers for processing during the daytime (work time) is logical. It has proven quite difficult to get people to move mealtimes from late in the day (to suit solar better) but that doesnt mean there are not applications for it. I recall the SK14 well. I entered a cooking competition using and SK14 and it definitely exceeded 200 C (cast iron 3-legged pot) when cooking with a small amount of oil. Regards Crispin
