that condenses humidity in the air instead of actual fog (which is easier). One billboard produces 96 liters of potable water per day.

Think of all the ugly billboards across California turned into something useful.

Oh, the lawns would still be brown and agriculture, which uses 80% of the water in the state, would still have to adapt to subsoil drip irrigation, but they'd survive more drought.

If they do nothing, there will have to be a mass exodus within a few years.
