Carbon-Based Fuel Cells: Clean Coal?

UserID 3.14 writes: "I got this story from the Lawrence Livermore National Lab web site. The idea for carbon anode electrochemical cells has been around for a long time, but waste ash was always a problem. The new system uses very fine particulate carbon for full conversion to CO2. The CO2 has non-polluting industrial uses, including refilling the used up oil wells (so they don't collapse). Of course, the greatest benefit of the whole scheme is how it almost doubles power extraction efficiency (up to around 80%)." The article has some good information about the differences between the types of carbon found in nature, too.
