Get them into deeper ocean levels or in places with a strong current and you've solved the problem, but this may add to the cost of the project or limit where you situate your desalination plants.<br /><br />They're also a problem if you're desalinating salty groundwater, which can happen far from a convenient ocean.Brianhttps://www.blogger.com/profile/09301230860904555513noreply@blogger.comtag:blogger.com,1999:blog-16612221.post-12167286868253451872013-10-29T07:08:05.742-04:002013-10-29T07:08:05.742-04:00FYI, IUDKTA, in UK TSET of the S of OP, funny?? h...FYI, IUDKTA, in UK TSET of the S of OP, funny?? http://www.keepcalm-o-matic.co.uk/p/keep-calm-and-eat-your-curry-4/Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-16612221.post-4174774308969207252013-10-28T07:01:07.917-04:002013-10-28T07:01:07.917-04:00These two are pertinent:

I've seen terrible problems when the water wasn't properly disposed of, entire hillsides dessicated, but I've never seen a problem once in the water and a simple examination of the problem pretty much voids that issue.

Storage quantities are perilously tuned; a little drought turns into a big shortage. <br /><br />The fundamental problem is that despite Istvan's being so impressed with elevations found on these islands, for the most part they're simply too low to produce any rain from adiabatic effects. They're naturally parched pimples for the most part. <br /><br />I suppose this has all been pointed out, ad nauseam. <br /><br />dbostromhttps://www.blogger.com/profile/13885863615343906724noreply@blogger.comtag:blogger.com,1999:blog-16612221.post-4836980422777693532013-10-24T15:47:59.315-04:002013-10-24T15:47:59.315-04:00I saw numbers that ( in the 90s ) humans were usin...I saw numbers that ( in the 90s ) humans were using the equivalent of 70% of total global precipitation.
