Distributed Water Desalination – Portable Boat Desalination Products?

Important idea

Could a distributed desalination system work. Portable marine desalination units. Looking at first unit I could find with google. The Rainman Portable Desalination. It does not look so big.

Since portable solar panels made a bigger difference to people lives than big solar farms. I wonder if the same could be true for water.

So the idea is for central water and distributed water to work together.

Everyone needs to have a portable desalination device and the needed solar panels.
