Check out this story on rapid CVD growth of single
The ultimate structural material would be carbon
nanotube reinforced diamond. Carbon nanotubes are
strong in tension, but floppy. Diamond is strong
in compression, but brittle. Combining them into
a composite structural material like concrete, where
steel reinforcing provides the tensile strength
and stone the compressive strength, would provide
a versatile product. It would be roughly 1000x
stronger than concrete. If it can be produced for
less than 1000x the cost, it would have wide use.
Finished concrete costs about $0.06 a pound, so
nanotube/diamond structures would need to be less
than $60/lb to compete at current costs.
