Low energy pressure driven atmospheric water generator

[Dave]

If you increase the air pressure the dew point is increased also. So
instead of direct cooling to get the water out of the air, you're
wringing it out instead.

A long time ago it was found by lift manufacturers that with balance
weights you don't need to put work in the move all the weight each time.
So therefore a 100m deep 3m wide salt water shaft can be used to lower a
collapsible bag of air with collector, when there is one coming up at
the same time on a pulley. Water resistance is a problem, but they can
use the hydrophobic shark skin material that is banned for competition
swimmers. Might actually be better on a continuous belt, you just need
someone to get the bottom of it, in case of problems.

Haven't done the sums; it's a good exercise for students.

No matter how you do it, it takes 2,260 kJ/kg to convert water vapor to
liquid water or vice versa.

Nope, it is just another of your brain farts since you don't really
understand physics.
