Carbon capture finding

Interesting biological study finds apparently efficient way to convert carbon dioxide into a carbonate via chemical reaction with nickel.  Comes from a study on Sea Urchins as reported by BBC news.

quote: "Researchers say that the natural ability of sea urchins to absorb CO2 could be a model for an effective carbon capture and storage system."

The process is also called "very cheap." The article discusses possible implementation w/ power plant and has a nice image detailing the flow of the process.
