There is always a need for water inland, whereas on the coast we can build desalination plants, inland there is no real prospect for this. If we were to observe that there is water in the air, in hydrogen and oxygen, then we could simply melt them together with long poles that go up into the air and 'run off' to a bucket on the ground, yes? this would see the water collected from the clouds and simply run down into a container, of course.
Another way to make water is to use electricity to power a fridge that makes ice, then wait for the ice to melt? Maybe if we were to observe that when jets hit mac one, they create water vapor? this would mean that they need to make something that goes round and round very fast, like a tennis ball on a pole, round and round it could go, or, set up windmill power generators and then see it through. Or, we could use electromagnetism to cross live wires to create water? this would be like wires generating sparks and the water falling from the wires?
"It takes water from the air and it captures it... Water Out of Thin Air? It Can Be Done, Say Scientists April 13, 2017 — People living in arid, drought-ridden areas may soon be able to get water straight from a source that's all around them — the air, American researchers said Thursday.
There is a new technology I read about yesterday .. Its small, solar driven and will pull 3 liters out the dryest desert air per day.
