Elongated fullerene carbon molecule in a tubular configuration. Nanotubes are cylinders arranged from a single layer of carbon atoms. They are are 10 times stronger than, and have a fraction of the weight of, steel. The self-repairing variant Polyfullene is particularly useful.
As well as being strong they are also heat resistant, formed from the same hexagonal patterns as graphene, arranged in three different ways; armchair, zigzag and chiral (each with a different diameter and bulk density).
An essential part of of nanotech and nanofacturing, nanotubes can perform the same electronic functions of silicon-based components, but at a much finer scale. Nanotubes are standard in mesoscale molecular computer chips because their electrical conductivity can be controlled by the extent they are twisted. During the middle information period, nanotubes enabled the continued exponential growth of computing and integrated circuits that was referred to as Moore's Law, as well as allowing the creation of three-dimensional circuits.
Other uses for nanotubes include spacecraft construction, beanstalk cables and other forms of space tether, and as reinforcement in rotation space habitats such as Bishop Rings and McKendree Cylinders. Because of their many useful properties, and the relative ease of construction, nanotubes are still manufactured in bulk, even in relative primitive polities and societies.
