Plans on how to construct a passive solar dehydrator?

Hi my name is Michael Mendez, I am a senior at Vandegrift High School, and I am a Life Scout in Boy Scouts working on my eagle project. I am trying to build a passive solar veggie dehydrator (in the style of the large outhouse looking ones) for Community, First!, a program with Mobile Loaves and Fishes to get homeless people into homes in a self-sustained village, in order for this community to preserve their food. I was wondering if anyone had any plans/ drawings that I could go off of in order to build this. My email is m.d.mendez1996@gmail.com , thanks!

Howdy Michael, welcome to permies!

there are links to several designs there.

I've built a couple of these with great results.
