Thought this was cool; sharing

Very cool to know there are cost effective methods for desalinating the ocean on the horizon! Hopefully this can be a reality within the next ten years or so and water shortages will be a thing of the past. Here's to dreaming .

An issue is is that this kind of separation only works in small channels (because of diffusion length of the ions). So to scale this up you have to make microfluidic chips in parallel which makes the whole thing more expensive. So I don't really see this becoming anything soon.
