Turning Carbon Dioxide into Stone

From ScienceFriday.com: "What if you could take CO2, pump it down a deep hole in the sea floor and turn it into something harmless? New research suggests the idea is not so far-fetched. David Goldberg, Taro Takahashi and Angela Slagle of Lamont-Doherty Earth Observatory published a study on the subject in the Proceedings of the National Academy of Sciences this week."

I am not a big fan of this type of technology, but it's interesting.
