== Reversible computing in rod logic as example context ==

One basically has a resonator going between 
★ the high efficiency energy buffer storage (main spring) 
★ the many springs of the FPGA like rod logic grid. 
with intermeiate enrgy storage in system inertia. 

The basic principle of reversible computing is … 
★ computing forward 
★ storing the result in a latch 
★ uncompute bacḱward 
… and do that in a hierarchical fashion and strategy 
… that is most compact in the spacetime of compute (time = compute steps here) 

Pulling the rods one by one must not intoduce problematic anharmonionicity. 
Smooth S curves better than harsh Z zigzag canm followers. 

If the inertia must be big enough to pull all rods 
and not run out of energy before and thereby miss some of the last rods to pull. 
So one wants some safe amount of overshoot in amplitude, 
but no too much as this needs space for that overshoot and time to do that overshoot. 
And a hard reflect to avoid that space an time need of the overshoot 
would again introduce some undesired anharmonicities. 

== Co-compute the inverse for constant energy turnover per cycle ==

To have predictable load and always the same overshoot 
it seems natural to always compute the inverse bits in parallel too. 

== Minimize energy transmission length by local energy recuperating resonators ==

The shorter the transmission of the energy the lesser the losses. 
Thus local sub resonators may well be desirable. 

== Challenge with resonator masses for dialing the frequency down to a good level ==

Inertial masses to get the frequency down are huge in size and atom count though. 

== Stay well below per rod resonance frequency ==

The natural "freewheeling" resonance frequency of the individual rods is much too high. 
It would lead to excessive frequencies and excessive power losses. 
★ Making revesible comuting pointless and 
★ when in in bulk even making cooling of the device impossible 
… even with the much more advanced [[diamondoid]] technology available. 

So there is a limit on how local one wants to go with the resonators. 
One inertia mass per rod or just the rod fatter would make the volume for each rod huge. 
loosing the benefit of spacial nanomechanical compute density (possibly useful for [[medical nano-devices]]).
