Default Paper published on producing arbitrarily long nanotubes.

Thanks for taking the time to read it. Right, these now are just proposals.
All of them though would be easy and low cost to test for nanotechnology
research labs. So considering the the billion dollar benefit in producing
structures a hundred times stronger than steel at 1/5th the weight, the
benefit to risk ratio is huge.
What goes into the risk calculation tough has to be consideration of the
likelihood they would work. For the simply tying the nanotubes proposal, as
I discussed in the article it has already been proven tying them together
can give lighter weight conducting wires than copper wires. And it is known
that tying ropes together can give ropes 80% to 90% the strength of the
component ropes.
For the laser irradiation proposal nanotubes were able to be combined by
illuminating the nanotube ends with a resulting strength close to the 300
Mpa(megapascals) tensile strength of the component nanotubes. It needs to be
tested though using nanotubes of the greatest measured strength at above 100
Gpa(gigapascals).

Finally, nanotechnology can now fulfill its potential to revolutionize
21st-century technology, from the space elevator, to private, orbital
launchers, to 'flying cars'.
This crowdfunding campaign is to prove it:

Next stop: the space elevator.


There was an awful lot of "might" and "may" in that article. Nothing
that suggested anyone has gotten a sufficiently strong construct out
to say a meter or even 10cm.
