Problem is that does not generate water. It just takes the water away which is then missing somewhere else and fucks up the other areas which would otherwise be in healthy equilibrium.

Wonderful. This is actually some technology that some desert countries in the middle east could use. Those loosely-stacked walls are perfect to take water out of the air in the chill of the morning. Walls of this kind have been used for ages in that region for this purpose. Having an autonomous building system would allow to spread this use.

I don’t understand what that means. How does a wall take water out of the air and why is that wanted?

I presume stones get cold during night, when temperature rise they remain colder than air so water in the air condensate on them. Why is this wanted? Well, to get drinkable water in dry areas?

Probably evaporative cooling effects.

Condensation. Stone wall is cold in the morning, humid morning air passes through it, water condenses on the large, cold surface, and drips down.
