Kondenscompressor is an invention with plastic bottles its drip irrigation using a resivour inside a bottle I don't know how to put pictures oh here's a link kondenskompressor.blogspot.ca its in Spanish but if you scroll down there's a picture. I like the subtereniean version. I think, I haven't made any yet.
Because this system depends on evaporation out of the small container and eventual condensation inside the later container with a little care
water that is polluted, full of excess salts/minerals/and heavy metals could be tusked as a primary water source allowing the Evaporation /
Condensation cycle to provide all of the plants hydration with very little clean water lost to Evaporation !

whats happening !

Yes. Jeff described the stuff in Al's link, when we were on the phone.
This could work as a slow release from saline water or from the succulent plants that do well in Jeff's dry season. Fleshy plant material could have the moisture removed in a contraption like this. The remaining dry material, could be used as a mulch.
I've tried this in my arid environment, simply filling the inner pot with water. The outer "greenhouse" was an 8 litre (2 gallon) bottle with the base cut off and the inner reservoir was a 5 litre bottle with the top cut off. Condensation would form on the inside of the 8l bottle but each day the reservoir was still at nearly the same level as the day before. I think what happens is that very quickly the humidity inside reaches 100% and there is no further evaporation from the reservoir. I decided it was more effective and less effort to simply water the plants rather than fill the reservoir. Maybe a bit more experimentation could improve the design. The key would be to ensure the reservoir container is hot while the outer greenhouse container stays cool to maximise condensation and drip-down.
