The saudis are developing a sun evaporator plant in the red sea which they say will desalinate sea water for $400@acre foot.
That’s impressive. Water from the colorado river to los angeles via the california aquaduct costs 948@acre foot untreated and about 1158 treated.
The world wide revolution begins when desalinated sea water for the deserts is cheap enough for agriculture. That’s around $300@acre foot for all foods except field crops like wheat and corn.
Very interesting information!
