The water crisis is a problem of export/import. Water does not disappear, it just goes somewhere else, the problem is that water abundant places have been relentlessly exporting water, in crops and other commodities, for decades and we are slowly starting to see the consequences.

Capturing water from air humidity does not solve this particular problem, what it could do is provide some househould sovereignty. Now maybe i am just plain wrong but i dont think this machine is more efficient than simply capturing and processing rain water, which is already abundant in high humidity places.
