US Patent 7655302 - Power transmission with nanotube fiber

In the 1990's a series of basic discoveries regarding carbon nanotubes were made by Richard Smalley's group at William Marsh Rice University. Patents based on this basic research are still being issued to Rice and are being commercialized by Unidym. This latest patent has priority going back to 1997 and is fundamental to power cabling systems based on carbon nanotube fibers. Claim 9 reads:

9. A high voltage power transmission cable

wherein at least one conductor comprises a continuous carbon fiber,

wherein the continuous carbon fiber comprises at least about 106 fullerene nanotubes bundled together in generally parallel orientation.
