Overview

next: further improvement at technology level III

Productive Nanosystems

In the beginning of APM research only assemblers where considered for reachig the capability to produce macroscopic amounts of a product.
At T.Level III it turns out that Advanced nanofactories are a more balanced and efficient than Assembler systems. At technology level I the border between minimal assemblers and rudimentary nanofactories is more blurred. A rudimentary nanofactory might be buildabel without self replicon but a simplified two dimentional assembler model might work well too.
To have an umbrella term for both ideas The therm productive nanosystems was introduced.

Using the whole volume for the building process of the product rather than a layer in the "classic" nanofactory design could speed up the building process. But this will not be neccesary for practical usage [TODO find existing proof]. If you build a solid block though you might end up to being slower than with the layer method due to the fractal growth speedup limit

Assemblers

Note: Assemblers are deprecated!
The idea is to create a machine with sidelengths of a few hundred nanometers which packages all the functionaliy to produce useful products and also make copies of itself.
This way you get an exponential rate of reproduction and can produce macroscopic goods in reasonable amounts of time.

It turned out that packaging all the functionality into such a small package is a rather unbalanced and inefficient approach for T.Level III.
[TODO add more detailed explanation wit assembly levels]

Quite a bit of thought was put into this model.

Either there where sopposed to swim about in a solution or there was some of movement mechanism in an machine phase scaffold crystal envisioned like:

• sliding cubes [TODO add references]
• legged blocks [TODO add references]
  

The combination of their appearance (legs) with their very tightly packed capability of self replication led to the situation that the public started to perceive this technology as swarms of tiny life like nano-bugs that could potentially start uncontrollable and unstoppable self replication. Why this is a wrong and misinformed opinion can be read up here.

The methods for movement are still relevant for higher assembly levels in nanofactories for transport of microcomponents. [and self repair by microcomponent replavcement ..]
The legged block mobility design is also known from the concept of Utility Fog (speculativity warning) but has other design priorities in an manufacturing context like more rigidity and less "intelligence".
