    They could be/are being used as nanowires, nanocapsulates, paper thin displays, transistors etc... they have excellent thermal conductivity, ..., and most importantly, depending on the details of their atomic arrangement, they behave as metals or semiconductors."

    The article defines nanotubes to be "...These cylinders can be a few microns or even millimeters long, with a diameter of the order of a nanometer..."

    What gives? How is a 10 um diameter tube a nanotube? Maybe I misread something. Please clarify! I've seen carbon fibers that were on the order of 10 um across.

    What you're missing is that these pictures aren't of single nanotubes, but rather of strips or strands consisting of numerous nanotubes, and they're not intended as microprocessor components at all. Nanotubes have potential applications all over, not just in microelectronics.

    These macroscopic fibers allow macro-scale experimentation on the properties of nano-tubes. While they are too large to serve as, say, interconnects on microchips, they have a host of other uses. While much is hypothesized about the properties of nanotubes, not much is known concretely. Hopefully, these will allow experiments to determine the actual physical properties of the tubes.

    The article also mentions using the nanotube fibers as a substite for existing carbon fiber components, which would allow these to become even lighter and stronger, and at first glance would seem to solve the problems some of these materials have with brittleness and low tolerances for linear stresses.
