The process is 70 percent efficient, double that of traditional coal power plants, ... in a single step, they can take pulverized coal -- or anything else that contains carbon, including human waste or banana peels, for example -- and directly transform the fuel's chemical energy into electricity by electrochemically oxidizing the carbon. The byproduct is carbon dioxide -- but it is emitted in such a pure form, Dubois said, that it's easy to contain. "If you have a conventional gas-fired coal plant and capture the (carbon dioxide) -- 75 percent of the cost is separating carbon dioxide from air," he said.
