The Carbon Nanotube Grows Up—Into Nanoyarn a Kilometer Long

Abstract:
One company's special manufacturing process turns out yarns and sheets millions of time the size of normal nanotubes.

When carbon nanotubes entered the spotlight in 1991, visionaries and futurists had a field day. The structural, thermal, and electrical properties of these cylinder-shaped carbon molecules meant that, in theory, they could be used to build incredibly strong structures, such as a space elevator that would stretch 62,000 miles from Earth, or incredibly compact and fast digital computers. In practice, however, it has been tough to mass-produce nanotubes that are long enough for engineers to do any such amazing things. Now Nanocomp Technologies, based in Concord, New Hampshire, is trying to bring the future closer by producing, in bulk, yarns and sheets made from carbon nanotubes.
