This sounds interesting, but they are relying on an awful lot of new technology.
Purifying water from ocean water is always going to be difficult, expensive, time consuming, and is only providing temporary solutions to the worlds water problem.
Here in california one solution to our water problem would be to provide more water storage. But, the assholes in charge won't do that.
That and stop trying to turn the Sacramento river into a salmon river.
ReplyDeleteOh, and the Delta smelt...maybe it should go extinct. It isn't like there aren't a half-dozen species ready to slide into that niche.
Yep. That fish is causing lots of problems.
DeleteMain reason with the fed gov involved with a project of water storage, not enough in kick-backs and graft and other shady state shenanigans... them poli-tick-ian want their honey.
ReplyDeleteWhat are the reasons or technologies that have to be overcome to make sea water desalination economically feasible?
ReplyDeleteI think the main thing is the electricity cost to power the pumps to pump the water. Large scale requires tremendous amounts of electricity. Another problem is disposal of the waste water. The waste water dissolved solids build up to very high levels, making disposal environmentally problematic.
DeleteI can surmise it would be salt that is the biggest solid, and trace metals that are in solution then are concentrated. Couldn't that waste water be pumped to a far deeper part of the ocean and dispersed over a wide as area as possible to reenter solution? Trace metals removed before being pumped back out?
DeleteThe cost to get the waste that far would be pretty high. It still might concentrate in that area if there isn't enough flow. I don't think removing the metals is an option yet.
