Adding 2 percent carbon nanotubes to 98 percent pure polypropylene plastic makes the mixture 40 percent stronger, Laine said. That makes it ideal for laptop computer cases, car bodies and airplane parts.

I am very skeptical of this idea, regardless of how much it it touted. For one thing, even if the structure gets built, wouldn't such a thing be very vulnerable to damage, not only by space dibris, but also by all sorts of earthly dangers, both natural and malicious.

i read that the first tether will be really thin, and then they will keep gradually weaving in other cables to make the structure stronger.

Easy way around it, just send up spools of Nanotube strands one by one and weave it from the Top Down. Do not send the entire thing up all at once, lets be realistic here okay
Well another way would be to build a mass driver to send payloads up. *shrug* Lots of ideas out there

As I understand it, carbon nanotubes are really strong, higher tensile strength than steel. However, they suffer from micro-fractures due to normal conditions, and those micro-fractures degrade the integrity of the whole structure. Over time, the structure becomes unstable.
