Nanotube-producing bacteria show manufacturing promise

The research team believes this is the first time nanotubes have been shown to be produced by biological rather than chemical means. It opens the door to the possibility of cheaper and more environmentally friendly manufacture of electronic materials

The photoactive arsenic-sulfide nanotubes produced by the bacteria behave as metals with electrical and photoconductive properties. The researchers report that these properties may also provide novel functionality for the next generation of semiconductors in nano- and opto-electronic devices.

What about the space elevator? can this help with the space elevator too? suddenly the space elevator has become cheaper? that would be big news!

They are making arsenic sulfide nanotubes and not carbon nanotubes. So it does not help the space elevator
