Research is progressing so fast, that it will be possible to have unimmaginable things.
As it is possible to create Gasoline from the air, it will be possible to condensate water vapor by microcondensation. A bottle made with a special material called "Stenocara hi-tech" seems to be able to produce 3lt of water per hour.
This means that we will be able to produce water where it is normally impossilble to find it, just microcondensing it from the air.
It also means that there will be no more water issue for any population in the world.
