As part of an innovative design in the manufacturing process, it is proposed to utilize direct in situ sublimation of molecular fullerenes from the nascent "soot", during continuous on-line production. Important parameters such as temperature gradient, inert gas pressure and residence time will be evaluated. The evolution of this Phase I project will naturally grow into the Phase II program wherein three further major concepts will be implemented. These advances will lead to more than an order magnitude decrease in production cost (<$300 /kg) in the short-term, and will set the precedent for large scale manufacture. The proposed Phase I/II program will result in a marked decrease in cost and greatly increased availability and quality of these fundamental materials in the immediate future. The demand continues to grow rapidly and practical applications are within range of the lower anticipated costs. ***
