Tiny electrical circuits with a single molecule for each wire have been created in the United States. These grids could replace silicon chips, making computers and memory devices much more compact and powerful than they are today. The grids comprise carbon nanotubes ... The grids practically build themselves ... This raises hopes that a nanotube lattice could form a computer memory ... with a storage density around 100,000 times greater than that of a Pentium chip.

Cylinders make circuits spontaneously
