In the film Waterworld, they have a device to purify urine - you crank the handle - but funnily enough they aren't using the device to clean seawater. Just another plot hole...
- iqster 15y agoThey have desalination plants in the middle east. The problem with those is that they are very energy intensive.
- latch 15y agoThe pacific is worth mentioning too...Singapore in particular, and Australia increasingly so. A handful of southern US states are getting things ramped up too.
- mahyarm 15y agoI think solar heat desalination plants in very hot climates like that could be more practical. +40C is fairly common in Singapore and the Middle East
- dalke 15y agoAnother problem is the output flow is more saline, which affects sea life.
- jonknee 15y agoThere's a large desal plant in Florida too, it supplies part of the water that I drink. You're right in that it's energy intensive, but at least in our part of the world the largest problem was water quality. There's a lot of biomass floating around in sea water and it means having to constantly repair the filters. I believe there was a big issue with an invasive species of mussels as well that do quite a bit of damage. http://www.tampabaywater.org/facilities/desalination_plant/index.aspx http://www.tampabaywater.org/facilities/desalination_plant/i...
