I was initially afraid this was going to be a solar self-filling water bottle KS. [0]
So, it's basically a porous mirror of the tried-and-true emergency solar water collector design. It seems legitimately legit.
I wonder if an extremely dark material (nanotube appliqué[1]) on a porous material would be able to process water faster?
The trillion dollar question is: How much material do you need to generate enough fresh water for an average human? And, can it be made more durable than a diaper?

- snypher 6y agoThe slightly smaller (billion dollar) question is fresh water to live, or, fresh water to wash cars/water gardens/et al? In my state the average resident uses ~120 gallons a day which I believe is far too much.

- scsilver 6y agoLooking at nature, excess/waste often leads to deterioration of a system, or atleast ups the probability of deterioration. In that sense, efficient systems are more sustainable, and nature rewards naturally selects that which sustains. Thats my moral opinion on efficiency vs abundance.
