The principle works roughly in terse summary description like such: 

★ At core: 
– First normal forward computation, but reversible, that is: Keeping all the inputs around. 
– Then saving the output using a reversible latch. 
– Then then backwards computation (aka "uncomputation") to free up the logic gates for further compute again. 

★ Then do this process in a hierarchical fashion, 
… where the data stored in the latches server as the inputs of further such processes. 

★ Furthermore there is optimization potential in compressing this (somewhat fractal) hierarchical process in space and time. 
… Initial optimizations are not entirely trivial but straightforward and self suggesting (at least in retrospect).

Rod logic may especially lend itself to educational illustration of the process. 
As in the [[mechanical electrical analogies]] 
– charges of digital bits are mapped to positions 
– currents are mapped to speeds and 
– voltages are mapped to to forces. 
– And most importantly: Irreversible energy dissipative deletions of bits are mapped to unconstrained snaps.
