This page is about a portion of highly targeted development towards gemstone metamaterial technology.

Here counting to "future-backward development" will be everything that is not yet accessible by physical experiment but that may already make sense to think about and work on.

Modelling as of yet experimentally inaccessible forms of mechanosynthesis

  • modelling mechanosynthesis of diamond and similar carbon structures and
  • designing a closed loop material processing circuit.

There has been a paper created on this. See Tooltip chemistry.

Maybe: Modelling silicon mechanosynthesis with better tips that are not yet experimentally accessible.

Exploratory engineering (EE)

See main article: Exploratory engineering A basis for a sensible far term target has been determined by Nanosytems but there surely is plenty of space for refinement.

Modelling of Crystolecules that cannot yet be built

Currently these should mainly be seen in the context of explotarory engineering. That is: Designing some explicit models of these at opposite ends of the design space can give some cornerstones to the patch in design space that contains feasible solutions.

As long as we have no experimental accessibility to the creation of crystolecules there is no point in designing parts for (and the whole of) complexly interlinking systems like e.g. recreating in atomic detail what is shown conceptually in the nanofactory concept demonstration video.

  • Auto generating various kinds of strained shell bearings for differently tight fits and
  • especially designing highly uncritical purely structural spacing Kaehler brackets

These might be some work that really may become usable in a 1:1 unchanged fashion at some point.

But much more than that these pretty colourful images and animation clips are useful for publicity. Or so one might thing.

Crystolecules akin structures that ARE already experimentally accessible:

Note that carbon nanotubes which have some similarities to crystolecules are already experimentally accesssible. Measurements of friction can and have been taken giving some clue and expermental evidence to the amazing properties that we can expect. Friction measurements on nanotubes of course already belong to the present-forward part of development. The thermodynamic synthesis technology of nanotubes is less targeted to advanced APM. That is more on the general material science direction.

Design of crystolecules for publicity reasons

These models are definitely nice and fascinating to look at. So one might be inclined to think that they'd be a nice selling point.

The catch is many scientist and material-science engineers get them in their wrong throat and misunderstand them as misunderstanding of basis physics. For some good but the wrong reasons.
See: Macroscale style machinery at the nanoscale.

In particular there is a stroboscopic illusion in crystolecule animations that can lead one to misjudge the operation speeds to be near thermal speeds and thus grossly misjudge the levels of friction.
