Comment But Charcoal floats! (Score 0) 145
Am I missing something here? They say they will remove Carbon Dioxide from the atmosphere, but at the end it says they will bury "carbon" under the sea bed. Carbon (also known as charcoal or graphite) is very light and will eventually float to the surface. Surely there are better uses for it? - maybe they could make millions of pencils for illiterate children in Africa?
