I don't know if the current density measurements will hold up. NASA Glenn 
was unable to reproduce them. It might be they used a different formulation 
then the original researchers used.

The link you provided by the Fraunhofer institute is interesting however. It 
shows the composites have about twice the strength as regular copper. This 
might be useful for applications requiring high strength as well as high 
conductivity such as overhead high tension wires.

Carbon nanotubes can revolutionize 21st-century technology IF they can be 
made arbitrarily long while
maintaining their strength.

Some proposals to accomplish that here:
