Here is some dehydrating links from the Noahs ark page.
I have worked up a pattern for a solar screen type dehydrator that is completely enclose that can be hung on some kind of a hook out in the sun. If anyone wants a drawn pic and instructions, let me know. I saw these for sale for quite a lot on a web site and decided to make my own. To make your own costs under $10.

Where do we get the sun from? Consider using waste heat from lights, refrigerator, and cooking.

Excellent point, Mike. This simple food dehydrator could be used before the pole shift to prepare food, and after in low light conditions using the residual light you mention.
