Solve for X: Rob McGinnis on global water scarcity

h/t Next Big Future

Absolutely amazing.

Basically he uses a more saline solution to get the water ( from seawater) to go into it, but the more saline solution has salts in it that are more easily removed from the water in order to purify it.  The water is heated, but not to boiling point, which means less energy is necessary.  The salts are easily recovered and recycled.

If you have the time, it is worth watching this carefully.
