Manipulation of the dielectric requires "work". How would you keep the dielectric continuously polarized without moving it?
I haven't been able to devise a set of experiments to answer that question. Obviously, my theories of how this all works are not complete, maybe completely off.
What I do know is polarization of this, or these, media is not polar, in the sense of having two distinct and different ends. The closest fit to the evidence is polarization involves curvature, possibly circular, spherical, helical, or all the above.
Does it require 'work' to get it going? I would say, yes, but only if you are trying to change the shape, direction or handedness it has already.
As far as keeping it polarized... I am starting to suspect we already have two excellent examples - magnets & electrets. I just obtained a handful of 70's vintage .05 mfd 3kV "Plastic" caps produced with 'accidental' ferroelectric properties. No matter how many times I short them, they always 'recover' to the previous charge within seconds.
The tech notes on the box (dated in 76) says the caps were faulty from the supplier and the stored charge caused circuit failure when used. They were jumped when I received them.
So, keeping a charge? My best guess is a static force is more like a soliton than anything else. Once it is going, your usage is more like riding a wave than draining a pond.
Smoke rings and plasma balls? My feet are on the ground. I just don't have a good understanding of it all, yet.
I'm still hoping to join your efforts, this weekend.
