Probably very dumb idea, but would it be feasible to just pump and sprinkle sea-water on hot, dry desert and let it naturally evaporate, and then collect it as fresh rainwater back? i.e. how much water would you need to evaporate to have a noticeable increase in rainfall?
In other words, you want to salt the land? Isn't that what marauders do when they want to destroy an area permanently?
Can I shower in salt water? Then all I need to do is desalinate drinking water. “Distributed” home desalination for drinking water seems like the best approach in my mind, then people can pay as much or as little they need, but I have no real data to back this up.
1. Steam distillation + Product can be perfect DI type 1 water - Expensive: 300+ kJ/L
2. RO membrane + Cheaper - Slow - Wastes more water - Requires regular changing of membranes
The end.

On top of that all the brine that people produce in their homes would have to be disposed of, and I'm sure many people would just end up flushing it down the drain. So the water treatment plant would have to deal with highly concentrated, contaminated saltwater.
Slightly off topic, however, the post references the Carlsbad desalination facility. If you find yourself in San Diego and like oysters, I would highly recommend you checkout the Carlsbad Aquafarm. Take the tour and pick up some oysters. What's really interesting and relevant to the topic is that the oyster farm serves as a pre-filter to the desalination plant and there's an symbiotic relationship between the plant a…
Stupid question time, why not expose the sea water over a larger area and expose to sunshine? There's plenty of room in the UAE for this, somebody is even building a wall that could hold the water which could be dual purpose and act as cooling via evaporation...

I'm not even remotely knowledgeable about this, but I'd assume saltwater would wreck plumbing. The connection in and out would probably be degraded much quicker. Then the water treatment plants would have to deal with dirty salt water, which is probably more difficult.

Some countries have floods in one part, and drought in the other.
The floods are so bad that large numbers of people die.
Here's a great challenge that should be worked on: how to capture the flood water and use it to mitigate the droughts. Could something like Elon Musk's Boring company concept fix this?
