High performance of gem-gum technology
This page is about collecting and listing various
aspects and performance parameters where future gemstone metamaterial technology
will have the potential to vastly outperform anything that we have today (time of writing 2021).
High performance from geometric scaling laws
- Scaling law: Higher throughput of smaller machinery
- Concrete consequence: Hyper high throughput microcomponent recomposition
The scaling law of higher throughput of smaller machinery, combined with other effects listed further below,
effectively overcompensates the scaling law of higher total bearing surface area of smaller machinery
that would, on its own, degrade performance by causing huge friction losses.

High performance from nanoscale specific properties
- Superlubrication and dropping friction even further: stratified shear bearings
Actually superlubrication is only zero for static friction. Dynamic friction is significant for higher speeds.
But the in Nanosystems proposed nanomachinery operation speeds speeds are low (around 5mm/s).
Opting for low speeds is possible mainly due to the scaling law of higher throughput of smaller machinery.
High performance of metamaterials
Ludacrisly high potential power densities:
- Electromechanical converter, Chemomechanical converter, ... Energy conversion
- Mechanical energy transmission – Chemical energy transmission – Energy transmission
- Thermal energy transmission => Diamondoid heat pump system
Unfortunately this does not apply to energy densities:
Unlike with power densities, energy densities won't see an in improvement of orders of magnitude.
Today's (2021..) chemical energies are already near the ultimate limit.
That is unless some very very surprising physics gets to be very unexpectedly discovered.
We absolutely won't make such fantastic assumptions on this wiki.
The baseline for assumptions on this wiki is the complete polar opposite.
The baseline is exploratory engineering.
High performance of base materials
- Highly temperature resilient base materials: Refractory compounds (where appropriate)
- High strength base materials: Base materials with high potential (where appropriate)
- High ultimate strength – Superhard materials / Refractory materials (these two often coincide)

- Highly (bio)degradable base materials (where appropriate). See: Recycling
Performance of piezochemical mechanosynthesis
Piezochemical mechanosynthesis#Surprising facts:
Reactions do not need to be highly exothermic to have low error rates.
When heavily optimized and slowly operated astoundingly high efficiencies may be reachable.
