===Worm Drive===

This model of a [http://en.wikipedia.org/wiki/Worm_drive worm drive] is based on a collaborative design by K. Eric Drexler and Mark Sims while working together at Nanorex. It is actually a sub-assembly of a larger design, the [[Molecular Machinery#Sorting Pump | sorting pump]]. This is the first molecular scale worm drive ever modeled in atomic detail and has been simulated using [[Software#NanoDynamics|NanoDynamics-1]], a custom MD engine integrated with [[Software#NanoEngineer|NanoEngineer-1]].

Below are two animation loops showing the results of an MD run of this model. In both animations, the front wall of the casing is hidden to allow viewing of the vertical worm gear in the middle of the assembly. The animation on the right shows all atoms of the casing rendered in tubes display style to allow viewing of the two worms and the worm gear. The two counter-rotating worms are the input gears, which then drive the middle worm gear.

In the rightmost image above, one quarter of the casing has been hidden to show the internal structure of the worm drive assembly.
