Modified Electrophorus (precharged variable capacitor)

@Kator01: Thank you for the information, I will write to 3M.

The electret  coax cable experiment is fascinating, I hope I can do it one day.My garden is large enough.

Greetings, Conrad

Good idea! I believe in experiments, Theories come after successful experiments.

Put two cylindrical magnets in a vertical tube with North poles facing each other.The top magnet should hoover above the lower one. But the top magnet is pressed closer to the lower one by gravity.

I think that nothing is gained.

Greetings, Conrad

yes
What is left then, is purely the electric force pulling the plates together against the magnetism (or spring).
when they approach a closer distance, the increase in attraction of the charges is weaker than the increase in repulsion of the magnets.

a spring is more linear, so the opposite situation can occur, where the electric force can overpower the spring at close distances.

it is interesting to think about, I might build one of each to play around with.

   It might be useful if you post what aspects of the  electrophorus ( or electrostatic-generators etc ) you want to know or understand more about, or find unexplained,   because,   it's such a founding block of physics,  surely the answers are already out there somewhere. 

( Maybe if you want an alternative electret,  maybe a container of very-fine-and-short-fabric-fibers( like microfibre fibers),   or the various types of packing foams,  or  very-thin-pieces-of-plastic, or paper,    or the types of dust that accidentally explode in grain-silos due to static( a less explosive choice ) ,  and maybe tightly compress it in a container that has  a  fabric-top  that lets air through it  )

But, here is what I wonder about,  regarding the  electrophorus,  electrostatic-generators,  and electrostatic-motors.
I'm only posting it to post it,  I don't require any answers.
-  When say for example,  and electrostatic-motor is making  little sparks between the stators and the moving-components,  is it possible that it is losing a higher-ratio  of Electromotive-force//Electrons  into the air,   than  when  electrical-current is just moving through conductors.
A hypothetical example,  during a spark through the air,  60%- electromotive-force  is totally lost to,  and absorbed by the air,   and 5%-electrons is totally lost to   and absorbed by the air.
Whereas in wire, due to existing resistance,   10%- electromotive-force  is totally lost,  BUT I ASSUME THAT NO ELECTRONS could be lost if they are only travelling through wire.
(  KEEPING IN MIND, that when the 2 sections of the  electrophorus  are not touching,  I assume there are little sparks occurring  when they are close  )

SO,  what would happen if you altered the ratio of  Electromotive-force/Electrons beyond a certain limit,  is all that happens is that the electrical-current stops flowing.
  - What happens if you have too much electromotive-force and too little electrons( or no electrons at all )
  - What happens if you have too many electrons,  and,  too little electromotive-force(or no electromotive-force at all )

But this is also related to something else,  I read a post about someone  using an arc-welder and claiming that it seemed to be generating more current than it was using,  in that particular case I suspect that the power-meter reaction to the arc-welder was to blame.

HOWEVER,  I have read about  electrostatic-machines  which have been claimed to take/absorb the  electrostatic-electricity  out  from the air/atmosphere,  and I have even seen a web-page of an electrostatic-motor powered by electrostatic-electricity which is collected directly from the air/atmosphere .

So that makes me wonder about the following analogy,  say you have the type of fountain with a very wide-flat-water-surface  flowing in a room  with  a very high percentage-of-water in the air,  could that water fountain absorb and remove a lot of the water in the air.
    NOW, what if you somehow managed to make a very wide-flat-surface-of-electricity  flowing through the air,  or,   even across the outer-surface  of an object,  could   that  wide-flat-surface-of-electricity   collect  electrostatic-electricity  directly from the air/atmosphere .
      -  And if so,   could you specially design something too alter  how much   electromotive-force  you collect from the air,  as compared to how many electrons you collect from the air.

    I definitely do not need an answer to any of these questions,  I'm only posting it if it gives anyone any ideas.

What I do not yet understand about the electrophorus:

- The role of the ground plate. Is it neccessary, can one connect my basic circuits (see my first post in this thread) from the moveable top plate to ground (without the second plate underneath the cake)?

- In geneal the role of a connection to ground. Is a ground connection helpful?

Hi Conrad,
ground connection should be a part of your working cycle,
