Cool, we’re definitely going to build some of these things on our property. I think a few additional ones that should be mentioned are passive solar thermal water heating (preferably thermosiphon style, where the heat source is below the heat store therefore requiring no electricity and no moving parts), passive solar south-facing porches for home-heating, root cellars for refrigeration, earth tubes / earth batteries, ram pumps, simple wind-mills, etc.
But then it is forced down over the drying screens because has no outlet at the top. It then finds it's exit at the bottom and is drawn up through the back chamber, finally exiting at the top back.

An inspiration for for people who are interested in appropriate technology,keep up the good work.
If only I were rich enough to afford low-tech.
On dehydrate, heated air moves upward .
