Perhaps to get this potentially excellent subject going someone out there would like to comment the uses of nanotechnology in the next 20 years.
The idea of building machines atom by atom or molecule by molecule intrigues me and I'd like to learn more than I already know.
In addition point your WWW browser to
http://planchet.rutgers.edu/intro.html for an intro to nantechnology.
[Actually, http://planchet.rutgers.edu/ itself, the root node, has
pointers to that and to other pages, the Foresight Updates, and
so forth.
