One exciting thing that has come out of nanotechnology research is the single-walled carbon nanotube. It is basically a very tiny (1 billion times smaller than a meter) tube that resembles a rope. Heating ordinary carbon until it vaporizes, then allowing it to condense in a vacuum or an inert gas creates them. The carbon condenses in a series of hexagons that curl and connect into hollow tubes. The most interesting thing about the nanotube is that it is the strongest, most conductive, and stiffest material ever made. It is sixty times stronger than steel. Many suggest that a nanotube cable the size of a human hair could easily suspend a locomotive or reach from the Earth to the Moon. Can you imagine a rope to the moon? Nanotube fibers can be used to make bulletproof vests that are 17 times stronger than normal Kevlar vests.

One of the advantages of using nanotubes is that because they are so small they are much lighter as well. All materials, which are made with nanotubes, will be stronger and lighter.
