This article is a stub. It needs to be expanded.
Screen capture from the video showing several processing stages highly compressed into just one image. Visible is (1) ethyne purification stages (2a & 2b) final transfer of ethyne out of liquid or gas phase and into machine phase (3) loading of ethyne onto tooltips (4) Abstraction of a pair of hydrogen atoms (5) deposition of a pair of carbon atoms onto a cube shaped crystolecule under construction (6) transport of along the assembly line. A real design: (A) would have these processing stages much more spaced apart (B) would have the tool tips running on chains too (C) would have the molecule sorting stages and final transfer to machine phase worked out in much more detail
Here is an alternate scene that did not make it into the animation video. The tips are on belts for longer tip-tip encounter time. It seem to suffers from being a too compact design though leading to a few issues like: The polygonal wheels may cause Van der Waals force spikes, the hinge flexing graphene sheet connections seems questionable and the axles are cramped. (wiki-TODO: figure out what mechanosynthetic reaction is supposed to be demonstrated here)

This page is about the the conceptual animation video "Productive nanosystems: From molecules to superproducts".
Watch it here: Productive nanosystems: From molecules to superproducts (InternetArchive link)
To address the common immediate concerns see: Macroscale style machinery at the nanoscale

Goals

Goals of the concept video

The goals of this animation presumably where a balance of:

  • accurate depiction of concepts outlined in the book Nanosystems
  • comprehensible depiction of concepts (not over designed over complicated – just giving a hint that there are plenty ways to do it)
  • manageable design effort
  • show the most critical components worked out in most detail =>
    less critical components are worked out in much less detail
    they are mostly shown to give a whole system context

Goals of this discussion page

This page is about a brief listing of the sequence of things shown in the video illustrated with screen captures.
Detailed discussions of the stations will be given on dedicated sub-pages.

Up: Discussion of proposed nanofactory designs

List of shown things in the first half

Shown wile zooming in continuously:

Shown while zooming out is a list of processing stations.

List of shown stations (as brief listing)

Stations dealing with molecules and molecule fragments:

Stations dealing with crystolecules and bigger structures:

  • Assembly line positioning stage – pallets (adapter pallets)
  • NOT SHOWN IN PUBLISHED VERSION – attachment chains for the tool-tips and back-pressure rails
  • NOT SHOWN – tooltip positioning stage
  • NOT SHOWN – switch of belt type and speed transition
  • NOT SHOWN – early stage vacuum lockout
  • Routing station (Distribution junction and merging junction)
  • Mixed part type stream transport to the next assembly level (here next assembly layer)
  • Stream pickup mechanism
  • First programmable assembly robot – details largely omitted
  • Part streaming assembly – this splits up into three sub processes – gantry robotics involved
  • Final lockout at the macroscale

List of shown stations (discussed in more detail)

(wiki-TODO: add discussions of stations and associated screencaps)

Sorting rotors

"Sorting rotors" is the name used in Nanosystems.

Possible critique points of what's shown in the animation:

Possible critique (1): "This has not been worked out in enough detail." – (not applicable when looking at additional work)
Well. Given this is a processing step of core importance there actually has been done more detailed work on this peculiar design problem. The results juts did not make it into the animation. Either for reasons-of-clarity or it may have been designed only after publication of that video.

Specifically an atomistic model of an acetylene sorting pump with the software Nanoengineer-1 was being designed.
See: Acetylene sorting pump – This was the biggest and most complex modeled diamondoid molecular machine element designed till 2021 (and going).

Possible critique (2): Potential critique points due to the integrated ethyne rods:

  • possibly higher radiation damage sensitivity.
  • the component parts are possibly quite a bit more difficult to synthesize

Are there maybe alternative solutions that can do without ethyne rods?
See discussion on the page: resource molecule sorting system

Notes

The page on this wiki that is associated is: Gemstone metamaterial on chip factories
The page "Advanced productive nanosystems" is more generally about all kinds of proposed advanced manufacturing systems (more and less feasible) that go into the direction of gem-gum technology.
