Cool computing

Nature Materials volume 2, pages 134–135 (2003)Cite this article

Proposals for carrying out computing at the molecular level generally involve current-carrying circuitry, as in conventional computers. A possible alternative, using an electrostatically operating 'cellular automata', reduces, among other things, the problem of excess heat production.
