I wonder if this could work in places with no ocean nearby just using rain water and rain water with added salt. Would you need an obscene amount of new salt/rain water?
- jandrese 7y agoThe energy cost of acquiring the salt would probably make it uneconomical. Plus you have to get rid of massive quantities of brackish water without a convenient ocean nearby. Maybe it could be used at the Great Salt Lake, but otherwise the options are limited.
- asdfman123 7y agoOne potential problem: you derive energy from converting freshwater to salt water. What do you do with all that salt water? You could cook it in the sun to evaporate out the water and start the process over again, but you've basically made a solar energy plant. The cool thing about using membranes near rivers and the ocean is it uses the ocean as your solar energy plant. You could also place this device near natural dead seas to produce power... but that's basically what the article is proposing.
