First Pure Nanotube Fibers Made

WallsRSolid Re:just the space elevator? (97 comments)

Nanotubes' 20 K critical temperature (T_c) does not come close to a high temperature superconductor.

High T_c is usually defined as above the boiling point of liquid nitrogen, a good, cheap, plentiful, environmentally-friendly coolant, which is 77 K. This implies that liquid nitrogen can be used to keep the material superconducting, a property which drops costs and engineering challenges dramatically. Nanotubes' more popular and practical properties are its tensile strength (i.e. space elevator), and its *thermal* superconductivity (i.e. badass heatsink).

Furthermore, it's ideal for high-power electrical transformer applications because it conducts electricity with low resistance in only one dimension, eliminating pesky, dissipative eddy currents. A friend of mine patented this application.
