Another carbon sequestering technology…

I came across an interesting PopSci article in my feeds today.  I though it tied in with some of what we were discussing in the rose garden.

The popular science article doesn’t go into great detail, but it does raise some interesting ethical questions.  If we could eliminate or capture atmospheric carbon, what effect would that have on the arguments for reduced fossil fuel dependency.  Also who owns the carbon?  Is it an energy by-product of the machinations of the entire human race?  Would we be purchasing something that we already owned? I suppose since we discarded it, the carbon no longer would be our property.
