Carbon nanotubes are like electrical wires, good conductors, but do not waste heat in the same way. The reason is that among the copper atoms of electrical cables there are chemical bonds that transmit the vibrations of heat. However, the atoms of nanotubes have no chemical relation to the environment. However, IBM Thomas J from New York. Physicists at the Watson research center have found that nanotubes also waste heat through a process called remote heat conduction. This means that nanotubes can be used as cables in nanotechnology, without risk of overheating.
