Yep, I do like the tech used in illustrating the relationships here.

I remember you posting this before but also with some extras 
that you'd added yourself. I think they showed gears or pumps
from Nanosystems.

My point is that the schematic is obviously wrong in terms of 
scale because it can't possibly be the same device at both the
nano and micron scale.  

I don't know if an artist produced the diagrams. They look to me
like the sort of hand drawn schematic that an engineer type 
might quickly sketch out. The only names associated are those
of Merkle and Drexler. 

A lot of people would not have good intuitive understandings
of the relative scales of biological structures such as red blood
cells and synapses because these things exist at scales that
are way below their normal sensory radar.
