Cool! With the size of the racks, I'm guessing you are going to make another heat collector? How are you planning to enclose the racks?
I am slowly working on an appalachian style dehydrator. I'd love to find some racks like yours, I may have to go to the city and look, none to be found in my area.
Keep us posted!

First go around was a fail. The box isn't what I would call air tight by any means, but the amount of moisture produced by the veggies all collected on the glass, and then simply dripped back down on the veggies.
I played yesterday evening and ran it thru the night simply using the fan (12v w 4 leds) to see what would happen, not too much really.
I cut a square in the back of the box to allow more air in, although it is still slightly covered by the outer flap of the box, and added a very small heat source - a 1 watt LED 12v E27 bulb. I ran it empty and was able to raise the internal temp by 5f, or roughly 85f indoors.
I just started it a little bit ago using only 1 rack versus the two,
so as it stands now, about 2.8 watts give or take, 233ish mah, running indoors. We'll see...
