It would be easy to dismiss the premise of a talk delivered yesterday at the 2008 Joint Meeting of The Geological Society of America, Soil Science Society of America, American Society of Agronomy, Crop Science Society of America, and Gulf Coast Association of Geological Societies, in Houston. But the audience seems serious enough.

Entitled "Taking the salt out of sea water" sound shopworn, but there's no doubting the need for additional supplies of fresh water in many areas. The UN estimates that, globally, 1.1 billion people lack access to sustainable, clean drinking water and that 1.6 million children die each year because of that lack of access. University of Nevada, Las Vegas (UNLV) geoscientist David Kreamer, noting that 37% of the world's population lives within 100 km of a coastline, proposes that mothballed naval ships, such as the decommissioned US aircraft carrier John F. Kennedy, be retrofitted to become mobile desalination plants. He terms it "practical." Sounds like it's anything but that, but at least the idea is being vetted by relevant scientists.
