Freshwater from salt water using only solar energy

Load salt on the huge cargo ships already crossing the oceans. Build machines that dump salt overboard slowly and continuously as the ships make their voyages.

The ships are probably full one direction (when traveling from countries that manufacture a lot) but relatively empty on the way back, so there's probably free space.

This idea assumes that the product consumer is the side which needs desalination. Unfortunately, in practice usually the opposite is true.

The core of the idea is to put it on ships. Using idle capacity is just a purely optional bonus. Ignore that part if you want.
