waynerad writes "For the first time, researchers have created a simplified method for making long, continuous, hair-like strands of carbon nanotubes that are as much as eight inches in length. This breakthrough, reported in the May 3 issue of Science, is a first step toward creating such products as microcables for electrical devices or mechanically robust electrochemical actuators for artificial muscles.
The researchers from Rensselaer Polytechnic Institute and collaborators at Tsinghua University in Beijing found that chemical vapor deposition (CVD), a widely used technique to grow nanotubes, has a high yield of long strands when a sulfur-containing compound and hydrogen are added to the process."

The researchers from Rensselaer Polytechnic Institute and collaborators at Tsinghua University in Beijing found that chemical vapor deposition (CVD), a widely used technique to grow nanotubes, has a high yield of long strands when a sulfur-containing compound and hydrogen are added to the process. Researchers have previously created nanotube fibers with more complex methods, but because CVD is commonly used to make nanotubes, it would be easily adaptable and more efficient for synthesizing the long strands for practical applications. This new method produced nanotubes that measured 20 centimeters, much longer than conventional nanotubes, said Pulickel Ajayan. http://www.eurekalert.org/pub_releases/2002-05/rpi -spl050102.php"
