Browsing yahoo, I found the following tidbit about a new carbon material form. Elemental Carbon has many fascinating forms, starting with crystalline (Diamond) but also Buckyballs, nanotubes and carbon fibers. The most compelling reason to push this revolution is the large potential source of carbon materials being output from next generation carbon scrubbers.
Graphene applications are exploding. Its showing potential in batteries, electronics/semiconductors and even network security
But, the really really big thing, is if we start using carbon as a fundamental building component, we're making carbon sequestration integrated into our lifestyle. This coupled with a carbon tax could make the first design team that makes the carbon scrubbers able to produce raw materials for the growing carbon economy (as opposed to the silicon economy) fabulously wealthy.
Finally, it seems that they're making the stuff a lot cheaper now (nice link from LaFeminista)
