Kind of interesting. It takes a look at how using carbon nanotube based membranes can filter (and de-salinize) water from the ocean to make it clean to drink. Could be a tremendous help for our increasing global demand for clean water.
"A carbon-nanotube membrane (quarter shown for scale).
The nanotubes are located at the center of each square.
Despite their tiny size, they can filter water more efficiently
than current larger membranes."
