The tubular extension of the fullerenes popularly known as "Buckytubes" are now available commercially in small quantities. Early measurements indicate that these tubes behave as coherent quantum wires. In short lengths they are expected to be the most rigid of all possible beams and effectively unbreakable even when bent in half. Grown in long ropes they are expected to form the strongest fiber ever made, with a tensile strength approximately 100 times stronger than steel at only one-sixth the weight. Short lengths derivitized at the ends will constitute a new branch of organic chemistry. These buckytubes may bring into reality old dreams of molecular electronics, and have application in virtually all technologies where electrons flow. Assembled in closest-packed crystalline arrays these tubes will serve as "seed crystals" for the direct, continuous growth of super-strong, light weight membranes, plates, tubes, and other structures made entirely out of carbon.
