    While it is true that human ingenuity has allowed us to overcome challenges thrown at us by geography, it is not true that human ingenuity has allowed us to overcome ALL challenges thrown at us by geography. We may need some ingenuity indeed to avoid going the way of the Easter Islanders.

    Julian Simon wrote about this in his book the ultimate resource.

    Who writes this stuff? Walt, do you have the slightest understanding of the second law of thermodynamics?

    If I had to guess…. neutralizing the chloride ions may cause the positively charged sodium ions a given packet of fluid to repel one another to the point that the population of sodium ions in the packet is significantly reduced.

    I’m not sure what happens to the chloride ions (is there a risk that they might plate out on an electrode somehere?), and frankly I’m not absolutely certain whether the above paragraph would actually work, but it sounds like it might be at least somewhat plausible.

    The desalinization rate (which the article emphasizes is very low) is probably proportional to the amount of power you pump in, keeping this legal under Thermodynamics. The important bit seems to be an absence of moving parts, and (possibly) an absence of consumables in the process (though the brine has to go somewhere.)

    Interesting stuff. I wish they’d publish more of the technical details.

    Have no fear. Environmentalist will put a stop to this. THEY CANNOT allow those poor people to get out of their poverty. That’s simply against the natural order of things.
