1. How can carbon nanotubes be used to make a space elevator?
2. Easy! Just stretch one into space, then put a tiny elevator inside of it!

You need many, maaaaaaany nanotubes which you have to build up into the space - with an elevator inside those building up nanotubes.

Was that just a question out of curiosity?

I see. If you are interest in it, you can calculate how many nanotubes you need to build them up to the space.

Diameter: <100 nanometer (1*10^-7 m)

Entrance to the space: 37 km
