LoL, I appreciate the input anyway. It’s all about getting us thinking, and creating solutions.

Thing is, physics requires the warm air to move up (convection). Tho’ it did give me a chortle. ;-)

If I did do it, I would for sure share. They have clay working tools, etc, at our local maker space. So it could happen.

The principle is simple enough. Look into ‘swamp coolers’ or evaporative coolers. They work well with adequate airflow, until the air reaches the point where absorbing more moisture becomes less efficient, somewhere around 60-100% humidity. More airflow with low humidity air helps. The solid state/ no moving parts is what fascinate me about this design.

The wall panel one in the first left picture is also aesthetic, and modular. Makes me want to cast some terra cotta. I"m trying to think thru how one would channel the cool air in the direction one would want it to flow, without electricity or moving parts. Sort of a funnel shape leading from the cooling part, to guide the cool air in the right direction regardless of the wind’s direction.

Thornless was also a ‘selling point’. Mine were a gift from another gardener. And being raspberries they try to spread beyond their allotted space. So I dig them and put them up on freecycle. It’s super popular, and they can spread their DNA in someone else’s garden. :-D

ooh, that’s a lovely rose.

Nice Pic!! We’re already eating some yellow thornless raspberries. Yay, Summer!!

Funny thing, turns out ‘shitting in the nest’ / destroying our one planet for profit isn’t particularly pragmatic.

I searched train rail bikes: https://www.riverfoxtrain.com/experiences/railbikes/

Tho’ what I was imagining was a ‘regular’ bike fitted with an outrigger to keep the wheels on the track.

John Jeavons book, How to Grow More Vegetables (than you ever thought possible on less land with less water than you can imagine) is a wonderful reference on the biointensive method (https://johnjeavons.org/books-and-videos/). And it’s now in it’s 9th edition.
