| Smalley - Rice University, Jianping Lu - University of North Carolina at Chapel Hill The goal is to make a wire with so little electrical resistance that it does not dissipate electricity as heat. Smalley says quantum wires could perform at least as well as existing superconductors�without the need for expensive cooling equipment. Smalley�s group has already produced 100-meter-long fibers consisting of well-aligned nanotubes. But the fibers are mixtures of 150 different types of nanotubes, which limits their conductivity. The best wire would consist of just one kind of nanotube�ideally the so-called 5,5-armchair nanotube, named for the arrangement of its carbon atoms. Existing production techniques generate multiple types of nanotubes, indiscriminately. But Smalley believes that adding tiny bits of a single carbon nanotube at the beginning of the process could catalyze the production of huge numbers of identical nanotubes�in essence, �cloning� the original tube.
