Devil is always in the details. If solar power is all you need, are there any other maintenance or running costs and how high are they? How much does it cost to make this medium (hydrogel membrane) that is used to draw out the water?
Also, based on the paper it looks like this would be more efficient and have greater utility somewhere like the Persian Gulf states, Northern Australia or other places that are consistently sunny and have high humidity.
Is there a useful product I can buy to turn my excess solar electricity into water where the air isn't quite so dry? Around here, particularly in the mornings, the humidity is quite high and practically all surfaces condense water out of the air. I'd love to capture some deliberately.
There are two options: 1. purchase a 12v refrigerator and turn it on when the dewpoint is achievable by the fridge and then run air though a baffled pathway within the fridge to capture the water that condenses out. 2. Use zeolite to adsorb water from the air and then boil it off with heat produced from your solar panels and recollect the water. I believe you can purchase units that do just this from https://www.skywater.com/

Reminder that the efficiency of such a device has a hard bound given by the laws of thermodynamics which doesn't depend on implementation details.
