Clever and simple concept: Investor sets up billboards, rents out the advertising space to clients, people get free water, advertisers reach a guaranteed audience, people don't have to waste time/money finding drinking water, hence they are more likely to be able to afford the advertized products/services.
Everybody wins.
I wonder if they are efficient enough to remain profitable with rising energy costs or if they could be powered by local solar alone.

#2 There are ways of getting water out of the air without using energy at all. Inspired by the Namib desert beetle scientists invented a bottle that fills itself.

So the average family uses far less than 30 l of water per month?

This total BULL. First of all the amount is a lie. T That is only enough drinking water for 35 people. Not even remotely close to "hundreds of families". The total cost of it would provide 1000X more water in tankers,or enough to drill several deep wells that would supply years of water. Another feel good load of crap likely funded by MY tax dollar!!!
