Go deep to make desal work along California’s coast
The world is running out of fresh water and now companies are using the high pressure of the ocean depths to push seawater through a membrane leaving salt behind. This month Scientific American reports a breakthrough in strategy of how to apply reverse osmosis without huge energy costs or negative environmental issues by allowing it to “happen naturally” using technology that harnesses pressure hundreds of meters underwater. … One such company with big but achievable pipe dreams for the California coast is San Francisco-based OceanWell, who announced a pioneer project called Water Farm1 (WF-1) with six Los Angeles-area water agencies this month.
