dna nanomotor advances

This is probably just a beginning for making nanomotors(and hence nanomachines) whether out of dna or not.  One can almost feel the affects of the recent advances in being able to make dna nanotechnologies.

On the other hand, I saw a remark by Chris Phoenix a few weeks ago(there was a dna nanotechnology article that I did not bother posting here); he said more or less, "yes, dna nanotechnology can eventually get there . . . bootstrapping to Feynman/Drexlerian nanomanufacturing . . . but, other pathways will get there sooner."  I'm thinking Chris Phoenix is thinking of stms and the new nano piezo advances that could help make at least microscale stms possible.  I didn't ask him what he meant.  I just figure he's in the know on stuff not mentioned.  If he's correct, there could be some surprising announcements in a year or two!

--------------------------------update for crazy science/tech for the day

This is a microelectrodynamicaly controlled sensor that can be used for cantilevers for atomic force microscopy; hence, for sizing down stms!(scanning tunneling microscopes; devices that can image and position single atoms; size these guys down, mass produce them on chips, and we can start to see some molecular manufacturing systems pretty soon!).

- another breakthrough that can help size down stms to at least microtech levels
