Lockheed Martin Throws More Dirt on Malthus’ Grave
starts with:
-----------
Cheap, clean water may soon be available for the whole planet. According to Reuters, defense contractor Lockheed Martin has developed a filter that will hugely reduce the amount of energy necessary to turn sea water into fresh water. The filter, which is five hundred times thinner then others currently available, lets water pass through but blocks all salt molecules. It will use almost 100 times less energy than other methods for making salt water drinkable, giving third world countries another way of expanding access to drinking water without having to create costly pumping stations.

This should be a great benefit to many parts of the world. I hope they get this into production soon.
