Howard Lovy's nanotechnology essay on H2O purification

Another essay from the always interesting Howard Lovy:

Carlo Montemagno makes molecular devices that contain “embedded intelligence,” each molecule working in tandem with another to produce a desired action. His first application? Yes. Water purification. “We use membranes incorporated with some molecules that selectively only transport water molecules through, and with very, very high efficiencies,” Montemagno said. “The end result is that projected performance is at least 100 times better, maybe 1,000 times better than the best … filters.”
