Nuclear engineers have a vision whose fulfillment will make plutonium-239 and uranium-233 the "dirty, cheap" fuels and will make coal the fuel of esteem. It will be valued for derivative chemicals and clean fuels and for metallurgical and electrochemical uses of its fixed carbon. In a coal technology devised to exploit these values, the recovery of sulfur will be a mere incidental. An immediate, properly financed effort to develop means for coping with sulfur can give us clean air with profit, help to conserve our limited supply of vital uranium-235, and take us a large step toward a coal technology for the 21st century.
