Sliding parts in a mechanical nanocomputer require no special lubrication.
Above: Mechanism for two nanocomputer gates, initial position. One control rod with two gate knobs is seen laterally; two more more rods with knobs are seen end on. Each rod with associated knobs is a single molecule.
Below: The lateral rod has been pulled to the left during computation. Notice that one of the end-on rods has now been blocked and the other one unblocked in mechanical mimicry of the transistor action.
