| Nanopaper Soaks Up Oil Slicks |

If you didn’t know better, you’d think it was paper. Because it is. But it isn’t. A team at MIT has developed nanopaper, which has all the qualities of regular old-fashioned paper, including size, weight, printability, cut-ability, even the way it’s made. But it’s far more than just paper. We’ve seen nanotechnology posing as paper before, but this is something exceptionally cool because of its function. Made of nanowires, this paper can sit on water for months at a time, soaking up to 20 times its weight in oil, while never soaking up a drop of water. It was created to help remove oil and other toxins after oil spills. To keep it from absorbing water, the nanopaper is coated with siloxane vapor so it repels water while attracting oil. Laid down on the tough-to-clean areas of spills, the sheets quickly absorb oil and store it in the itty bitty nooks and crannies made by the clumped-together nanowires (think: butter in an English Muffin), making the toughest parts of cleaning up spills a whole heck of a lot easier. The best part is the sheets are reuseable. After absorbing all the oil it can gather, the sheets are boiled, removing the oil, and then reused. Shhh….do you hear that? Seals and seagulls are cheering. Via Discovery

Seagulls won't be cheering for long

Oil pollution is bad enough, so why is it necessary to pollute the oceans with nano wires? The constant flexing of the wires from the wave motion will see to it that these things break up.
What damage will nano wires do to the seagulls?

"What damage will nano wires do to the seagulls?"
You can't tell me you think that the chance - the tiny, negligible chance - that this particular material will pose a threat to seagulls outweighs the absolute, 100% certainty that being coated with bunker fuel WILL harm seagulls. This is EcoGeek. EcoWorrier and EcoWhiner may be more your style. There's not the slightest reason to believe that nanowires will pollute or cause issues, particularly when they're bound together into a cohesive sheet. It's a sad state of affairs when the desire to protect the environment turns into a reflexive, Luddite panic that anything and everything will harm the environment.

I wonder what chemicals are used in order to make the paper, but other than that it seems like a great solution!

As for the seagulls and other wildlife, NPR had a program about bundled nanotubes being as toxic as asbestos. There is a real solution for getting bundled nanotubes out of your system but there is a way to unbundle nanotube thanks to this kid, Philip Streich. So the wildlife could probably be treated somehow but it seems easier to come up with a new solution for the oil slicks.

Science, technology gadgets and...baby seals. We're in a bit of an eco-mess, but we've got the brains to lick any problem. And that's why EcoGeek.org publishes up to ten stories daily about innovations that are saving the planet.
And if that sounds interesting to you, then congratulations, you're an EcoGeek.

Do we make the nano-wire-textile? or should we take something that is already available and considered a waste product?
