Molecular Machinery: различия между версиями

This molecular [http://en.wikipedia.org/wiki/Differential_%28mechanical_device%29 differential gear] was designed by K. Eric Drexler and Ralph Merkle sometime around 1995 while working together at Xerox PARC. In the animated sequence above, you can clearly see the casing and six components of the internal assembly as each is hidden in the cutaway view.

This animation loop shows the results of a molecular dynamics simulation done with [[Software#NanoDynamics|NanoDynamics-1]]. The frames of the animation loop were rendered using POV-Ray, generated automatically using [[Software#NanoEngineer|NanoEngineer-1]]. The gearbox casing was hidden to expose the internal gearing mechanism. Notice that the front and back shafts rotate in opposite directions.

''"That is also a rotary motor driven by gas pressure if you operate it in the opposite direction. Push gas through it and you’ll get rotary motion. It’s a really nice motor."'' - [[Robert Freitas]]

This design of a neon pump includes two components. The pump casing, which includes a chamber wall with a hollow tube containing the rotor housing, and the rotor itself. In one mode of operation it could serve as a pump (for neon atoms) and in another it could be used to convert neon pressure to drive the rotor, making it a rotary motor.
