This is a potential game-changer. With the US's coal reserves AND a way to use them without polluting or releasing CO2, this has the capability of "flipping" the oil-based economy and dependency that many nations are dealing with.
Very exciting prospect. Though I would also still like to see more progress and investment into [url=http://www.extremetech.com/extreme/143437-uranium-killed-the-thorium-star-but-now-its-time-for-round-two]neighborhood thorium reactors[/url].

Excellent. However, coal ash can still be a serious environmental pollutant if handled carelessly. Although, this new method isn't quite proven yet, especially in the Megawatt range of power generation that most coal burning plants put out. Most coal burning plants are already pretty clean so long as the emission guidelines are kept. The main discharge is Pm10 and Pm2.5, as well as the main constituent of combustion, carbon dioxide. NOx is kept to a minimum, and even then, catalytic devices, AKA scrubbers, are used to eliminate those from the emissions. CO2 sequestration work needs to be worked on as well so proper storage of the gas can be dealt with as well.
