But also constantly (and strong enough). It is - perhaps - 
easy to create a *temporary* asymmetry.

----    ----    ----    ----          fixed multi-plate
  < ----    ----    ----    ----      sliding multi-plate

(You can also imagine round multiplates, one fixed and
the other spinning).

Due to the "lateral" Casimir force, the sliding multi-plate
moves to the left, because the plates of the sliding multi-plate 
and of the fixed multi-plate tend to overlap. During the
process the sum of field energy and mechanical energy is
(supposed to be) constant. 

----    ----    ----    ----    fixed multi-plate
----    ----    ----    ----    sliding multi-plate

But when you get the configuration here above, how
to create a new asymmetry?
