Re: Solar cooking
I recently did an internet search on solar ovens and was amazed at the variety ovens available. One article discussed the ratio of reflective surface to oven temperature and it seems you can modulate the oven temp easily enough, which you would want to do for dehydrating purposes.
When I was in Korea way back when, I saw women drying sliced fruits and vegetables on pretty much any flat sunny surface they could find. Few Koreans had refrigeration then, so they depended on dehydrated vegetables and fruit during the winter.
It would be easy enough to spread netting to control flies when in vicinity of land.
