'Electron Turbine' Could Print Designer Molecules

from the New Scientist

A carbon nanotube that spins in a current of electrons, like a wind turbine in a breeze, could become the world's smallest printer or shrink computer memory, UK researchers say.

The design is simple. A carbon nanotube 10 nanometres long and 1 nm wide is suspended between two others, its ends nested inside them to form a rotating joint. When a direct current is passed along the tubes, the central one spins around.

That design has as yet only been tested using advanced computer simulations by Colin Lambert and colleagues at Lancaster University, Lancashire, UK. But Adrian Bachtold of the Catalan Institute for Nanotechnology, who was not involved in the work, intends to build the electron turbines and says it should be straightforward.

The automation of tasks at work and at home is just around the corner, including driving cars, piloting planes, delivering packages, and transporting weapons. Unmanned aerial vehicles are rapidly evolving to meet both society’s and the military’s needs in automation and better efficiency.
During her time as one of the first female fighter pilots in the US Navy, Dr. Missy Cummings observed that computers could take off and land a plane more precisely than humans. Because of this breakthrough and her fascination with this growing technology, she began human–drone interaction research.
