no great progress in desalination (get cost down dramatically) on the horizon? then the export could suddenly go west east...
so soon we can double the population and make also Sahara green...The Green-Blue Planet!
Impressive. The article gives the capacity of that Storek plant as 627,000 cubic meters daily, which is 508 acre-feet. California's largest desalination plant in Carlsbad (about 50 miles south of me) produces up to 56,000 acre-feet yearly, so only 153 acre-feet daily. And, currently, it's very expensive water:
The largest, by far, is a $1 billion plant on the coast in Carlsbad, 35 miles north of San Diego, that opened in 2015. The largest desalination plant in the United States, it generates up to 56,000 acre-feet of water a year — roughly 8 percent of San Diego County’s water supply. But the cost is high, from $2,131 to $2,367 an acre-foot, depending on how much is produced, which is double the price that Metropolitan Water District of Southern California charges for the same amount of water from other sources such as local dams, the Colorado River or the Sacramento-San Joaquin Delta. By comparison, the Santa Clara Valley Water District in San Jose pays about $400 an acre foot for water from the Delta
Wikipedia says Storek costs (less than) $0.40/cubic meter, so $493 per acre-foot. If true, also impressive! Agree desalination will be more and more an important component in future. California is really just getting started in that technology: source here
