Subject: Nanotweezers for the New Millenium

The Tuesday December 14,1999 edition of the Vancouver Sun
carried an interesting article from the Washington Post entitled:

World's Tiniest Tweezers Latest Tool for
  Altering Single Molecules.

Quote:

  "Charles M. Lieber of Harward University and a colleague
crafted a pair of "nanotweezers" by attaching two bundles
of carbon "nanotubes" to either side of a glass rod. The
bundles, a mere 50 nanometers in diameter, open and
close when a small jolt of electricity is applied. In tests,
the tweezers could manipulate polystyrene spheres 300
nanometers in diameter and semiconductor wires 20
nanometers in diameter."

  My thought is that a mechanical computer could soon be
built  with nanotweezer equiped nanorobots manipulating a
nano-abbacus with nanobeads.
