Coal-Fired Jets ?
Coal's stability in high temperatures could make it an ideal fuel for the next generation of military aircraft. A thermally stable coal-based jet fuel is now being developed at Pennsylvania State University's Energy Institute. The fuel can absorb significant amounts of heat and not decompose at high temperatures; decomposition creates deposits of carbon that befoul engine parts. According to the researchers, the fuel could be manufactured in existing refineries and would produce no ash and very low sulfur.
