|'In the simplest sense, combustion is a chemical reaction that consumes oxygen and produces heat,' Fan said. 'Unfortunately, it also produces carbon dioxide, which is difficult to capture and bad for the environment. So we found a way to release the heat without burning. We carefully control the chemical reaction so that the coal never burns--it is consumed chemically, and the carbon dioxide is entirely contained inside the reactor.'|
