Nanorex have produced a “simulation of the molecular bearing design on page 298 of “Nanosystems” by Eric Drexler.” Christine Peterson at Foresight points out that “he most interesting part is toward the end.”
Presumably that refers to the caveat that “Producing structures of this kind will require molecular nanofabrication techniques that have yet to be developed” which seems to put this type of work firmly in the science fiction category.
