Dry your fruit, vegetables, and other goods with your own sun powered dehydrator. Electric Food Dehydrators can be expensive and consume unnecessary energy. This solar dehydrator was made entirely of recovered materials.
First we need an old window, I got mine from a construction site. Its your basic old nasty basement window. Make sure you wash both sides of the glass well with soap and water and window cleaner, more dust means less light gets through to your solar cells. Next take your multi-meter and sit in a sunny spot (or under a flood lamp) and check all your cells to make sure they get about .5 volts per cell. You do this by gently (cells are REALLY fragile) putting the red on the front (make sure its on the little metal lines) and black on the back (any place) of each cell while it is in the sun.
Mike Davis is an astronomer. To practice his hobby away from the light pollution of cities, he bought some land in a remote part of Arizona. But there was a problem: No electricity. But he's a resourceful fellow. He built some solar panels using inexpensive blemished and damaged solar cells from eBay!
