{{todo|This still needs much closer investigation to arrive at more reasonable but still safe lower upper bounds}}

Basically what always works is assuming the whole bond energy being dissipated across every mechanochemical reaction.
* This vastly overestimates dissipated heat.
* This still leads to practical (albeit slow) [[productive nanosystems]]
