szczys writes: Carbon Nanotubes and Graphene breakthroughs pop up in the news often enough for them to be considered buzzwords. Most of the time it's the superconducting properties of graphene that are touted, but molecule-scale structures also hold the promise of building mechanical computing devices that are unimaginably small. The reason we don't have these things yet comes down to the manufacturing process. Building machines out of carbon molecules is commonly called Rod Logic — a topic many know from the seminal novel The Diamond Age. Al Williams discusses how Rod Logic works and highlights some of the places we're already seeing these materials like to help cool LED light bulbs, and to strengthen composites.
