Solar powered apple dryer

Nick, Scott and I are constructing a solar powered apple dryer to improve our dehydration efficiency come autumn. Last year we used the oven and a big computer fan. It was non-ideal: too little space, too high of a temperature, too great a risk of melting a computer fan. 

Scott modified the very swanky design described here to reflect our more modest aims; and the fact that we already had a spare storm window and bookshelf. Today we assembled the heat generation zone. Next it needs racks, doors, and a vent. Then we just need a sunny day and some test apples.
