Basically, a device based on a capacitor principle, or electrophorus principle, and using a perpetually-charged dielectric-plate( like the dielectric-plate in the electrophorus ), a component like the dielectric-plate, but one which never loses it's electrostatic-charge.
( At the moment, the only the only thing I have found to use as a perpetually-charged dielectric-plate, is in fact a Permanent-Magnet )
I don't have any specific design in mind, although I guess it 'may' have to be more like a capacitor rather than an electrophorus if you wan't it to be solid-state, but that may not necessarily be true.
So I'm wondering if you can use a dielectric-plate( like the dielectric-plate in the electrophorus ) to get a capacitor( not an electrophorus ) to dischgarge, surely that would be difficult.

A Permanent-Magnet Has An Electric-Field, So It 'May'( or may not ) Be Possible To Use It As A Perpetually-Charged Dielectric-Plate( as a dielectric-plate in an electrophorus ), To charge Up A Capacitor
- The proof that a permanent-magnet( an unpowered-magnet ) has an electric-field can be viewed when a magnet is frozen solid in water, the Electric-Field then becomes clearly visible
In the webpage below, find the text - "Notice the angle of the electric field thats perpendicular to the magnet" - , to see the photo of the frozen magnetic-field of a permanent-magnet

However, I wonder if when you freeze a permanent-magnet, it may become closer to being a super-conductor, which is actually different to a room-temperature permanent-magnet, but obviously a frozen permanent-magnet is not as cold as a super-conductor( a much lower temperature, frozen permanent-magnet )
( At first I thought surely there's no way that a 'permanent-magnet' has an electric-field, but then I remembered that all atoms, protons, and electrons, have an electric-field, and since all the atoms in 'permanent-magnets' are aligned in one direction, then I guess it may be possible that the electric-field of 'permanent-magnets' may be aligned in one direction, but I don't know )

An alternative to using a 'permanent-magnet' as a dielectric-plate( like the dielectric-plate in the electrophorus ), could be to use the capacitor/electrophorus discharges in the device, to keep the dielectric-plate perpetually charged up.
Permanently charged cap exists an is called an Electret.
QuotePermanently charged cap exists an is called an Electret.
Today I discovered the modern types of electrets which seem to last for 20-years( some last longer ), which would be good enough for any device.
Before I only knew about the old types of electrets like bees-wax, resins, etc, which only last a few days or so.
From the description you typed about how capacitors work, on the other thread, it seems like it may not be possible to charge up a common capacitor( not an electrophorus ) to make it discharge,
just by using an electret, unless, you replace 1 of the 2 plates in a capacitor with an electret, in which case it becomes an electrophorus
