View source for The challenge of high speeds near nanoscale

'''Disclaimer:''' This page is not about feasibility analysis of [[advanced productive nanosystem]]s like [[gemstone metamaterial nanofactories]]. <br>
Such systems propose very low speeds in the few mm/s range. <br>
This page is about speculating over some exotic potential application cases <br> 
that are pushing the limits of what is possible possible and as part of that would need much higher speeds. <br>

[[Superlubricity]] is only about static friction being zero. <br>
Dynamic friction actually grows quadratically with spees making higher speeds a challenge. <br>

'''Strategies for somewhat higher speeds:'''
* [[Infinitesimal bearing]]s
* going for gearbearings with rollers avoiding sliding
* if gearbearings then going for bigger gear-rollers eventually microscale or even mesoscale

'''Strategies for even higher speeds'''
* Electrostatic levitation (some remnant waviness of the potential shrinking with distance)
* See page "[[Levitation]]" for more ideas.

If the aim is high-speed-transport of solid-state cooling-pellets then quality of thermal contact is of concern too. <br>
Electrostatic levitation basically only allows for EM radiative cooling. <br>
