US Patent 7615204 - Super long carbon nanotube strands

http://www.freepatentsonline.com/7615204.html

This patent is based on a collaboration between Rensselaer Polytechnic Institute and Tsinghua University and teaches a CVD fabrication method capable of producing long carbon nanotubes which may make the development of some speculative projects such as the space elevator more attainable. Claim 1 reads:

1. A continuous carbon nanotube strand having a length of at least 10 cm when it is directly synthesized.
