        If i could be arsed I'd google that... but I seem to recall it's either reverse osmosis or evaporation /condensing technology

        The first produces brackish water the second eats energy but could be viable in a hot climate

          A lot more expensive than importing bottles of mineral water, I suspect...
          Of all tyrannies, a tyranny sincerely exercised for the good of its victims may be the most oppressive. It would be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience.

            Grab an iceberg detaching itself from Antarctica because of global warming, and tow it to Melbourne.

              NZ can run a hosepipe across, we have loads of fresh water. We will only charge them a small tariff

                    Yes, it's an expensive business.

                    In the last 30 years, the amount of energy required for desalination has fallen precipitously, and along with it the price. Decades ago it took approximately 12 kilowatt-hours of energy to produce one cubic meter of freshwater using RO technology; today it takes on average between 3 and 4 kilowatt-hours of energy. Even today, however, the cost of that energy makes up about 40 percent of the total cost to produce each cubic meter of water.
