Clockwork automata on the micro-scale.

An article in the New Journal of Physics this month postulates a novel use for the not-yet-extant technology of nanotechnology: Building clockwork computers on a microscopic scale. The idea is that electronic circuitry isn't suitable for some environments but difference engines constructed on a microscopic scale might be because they would be far more precisely engineered and constructed with more durable materials. Sure, they'd be slower than conventional integrated circuits, but for some applications (like monitoring engine timings) you don't need a processor that can play Doom 3.

I hate to break it to them, but this isn't a new …
