With desalination, the plants need to be near the coast.  Seawater is taken in, put in the solar heated containers, some water is extracted, then the remainder is returned to the sea slightly more saline than before.  If the plant is too far inland, it requires too much energy to lift the seawater.

 

 

>…  I do like towing ice which I have seen in several books.  Are you saying that reverse osmosis is the last, the only tech that could do this job?  No more ideas needed?  In fact, could you say that about anything else?  That no further improvement can exist?

 

You could use nuclear-powered distillation but that hasn’t proven economically viable anywhere.

Land close to the sea is very pricy stuff and very limited.
