Bearing animation video
This video was created using the simulation facilities of NanoEngineer-1 (see http://www.nanoengineer-1.com), together with open-source animation tools like Pov-RAY, ImageMagick, and mpeg2encode. This is a simulation of the molecular bearing design on page 298 of "Nanosystems" by Eric Drexler. When viewed at 0.15 picoseconds per second of animation, thermal motion of atoms (particularly hydrogens) is visible. At 0.6 picoseconds per second, thermally excited mechanical resonances of the entire structure are seen. At 6 picoseconds per second, the rotation of the shaft (one rotation every 200 psecs) becomes apparent.
