A cheap, environmentally sound technique has been developed for producing nanotube ropes that could be used to make super-strong cables for such applications as a space elevator.


Carbon nanotubes are tubular carbon molecules with properties that make them potentially useful in extremely small scale electronic and mechanical applications.

They exhibit unusual strength and unique electrical properties, and are extremely efficient conductors of heat.



Of particular interest for the construction of super-strong cables is the high tensile strength of nanotubes—their ability to stretch without breaking or losing their shape.
