Great program today about carbon emmissions today on the Diane Rehm show. — http://thedianerehmshow.org/shows/2016-01-06/environmental-outlook-a-new-push-for-carbon-removal
Have also been trying to find the PBS NOVA Science Now esegment I saw years ago that better explained how readily carbon bonded with just about anything.
It may have also talked about advanced carbon-based nano-filament composite materials for advanced engineering projects, such as the sci-fi inspired “space elevator”.
Some of our “sequestration” of carbon may have to be about separating carbon from gases and liquids, bonding it as solids, and building structures. I’ve talked a lot about better managing our water suplies. That may require a lot of concrete, steel, plastic, or more advanced materials that need carbon.
