"Heating, Not Burning, Coal" "Fan discovered a way to heat coal, using iron-oxide pellets for an oxygen source and containing the reaction in a small, heated chamber from which pollutants cannot escape. The only waste product is therefore water and coal ash -- no greenhouse gases. As an added benefit, the metal from the iron-oxide can be recycled" I think its a good idea. More of it please. http://www.foxnews.com/science/2013/02/20/coal-cleanest-energy-source-there-is/ Yes its from fox. Good read anyway.
