Well, one must consider although we now have achieved success
pushing atoms around using SPM's, (ie. IBM's xenon atoms) we have not
yet accomplished the feat of creating covalent bonds.(such as nature
does) The closest we have come to this is Nadrian Seemans nanorobotic
arm, made out of synthetic DNA. Until this point has occurred, an
assembler will not.
In the meantime, this is the reason we are exposed to these
nanoscale evolved technology. The more we create application's on the
molecular scale, we find more windows of opprotunity for advances.
There will most likely be in the near future, nanoscale resistors
(Mitre corp.) and nanochips, quantum dots, nanowires etc. This is
part of the process to getting to the big picture, and nanomachine
(manipulator, replicator).
There are zillions of similar potential applications on the
nanoscale. We will first see, paint on watches, retractable doors and
floors, flat wall sized thin 3D tv's (holography), cars with total
saftey measures, virtual reality games, doggy dung cleaners, hobbies
such as railroad nanoscale models, refabrication of clothing, arrays
anyways, I could go on, but these are the early applications of nano.
Nanomachines are composed of simple, nested geodesic skeletons
and extensible rods, with no more computing power than today's
personal computers. Not to tremendous a task to design machines with
nanometer-scale components, but how do we construct them?
"One at a time". We can manipulate atoms at the nanometer scale
and build more complex machinery at the micron scale. (e.g. computer
chips) Given the pace of technological development, we will see
machines of this complexity built by hand soon. But to be useful, we
will need trillions of them- one trillion would fill a single cubic
centimeter. Shortly after the first is built, they will be
manufactured in quanity.
If a factory has ten million assemblers (that has taken years to
create) each capable of producing ten thousand machines a day, it
will take two weeks to produce a cubic centimeter of finished goods.
During this period, nanomachine based products will be rare and
expensive.
Eventually replicators will produce assemblers, which will then
produce nanomachines for final use. This will be in constrained
environments and will last for some time. Consumers at this time,
will not have access to replicator technology, but will be a time
filled with easily accessible nanomachinery. We may also use genetic
engineering to in fact "rip off" the nanomachinery of living
organisms to make nanomachines. This would lead to serious
restrictions however. (depending)
Also involved in the construction of such a machine, is energy
source-(most limiting aspect-nanomachines can be energy thirsty),
communication-(machine parts able to interact with eachother and
follow their commands), processing power-(each machine needs storage
and computing facilities- 1,000times the computing power of today's
personal computer), shape-(ie -buckyball or other micron-scale
geodesic structure) and scale.

>One thing I haven't noticed with nanotech research is that nobody
has yet developed a normal scale universal assembler, not to mention
one that can replicate itself. From what I've seen, all nanotech
companies are trying to build the final generation at the nanoscale
first, which seems awfully bassackwards to me. Thats tantamount to
having an R&D project during WWII to build a Pentium III chip. I say
build a human scale assembler, that you can program to create any
item wanted (especially items larger than itself), and then develop
an assembler that can not only do that but replicate itself. Once
this is achieved, work on making successive generations smaller until
you get to the nano scale.
