well maybe I could have used a comma there or something

"In his letter (in 1775) to Priestley, Volta says :"Che se a voi non dispiacesse, ardirei pure imporre un nome al mio picciolo apparecchio, e sarebbe quello di Elettroforo perpetuo".

That is standard English grammar.

Volta wrote Priestley a shitload of letters. The one in which Volta talks about "Elettroforo perpetuo" is commonly known as "Letter to Priestley"

What Volta means by this is that on his device the charge stays on the dielectric. You can put the metal plate back on top and the metal plate gets charged again and again. You can zap the charge from the metal plate to other stuff to deplete the charge. Then put the plate back in and it will charge again. The charge will fade from the device if it sits for a while.

I will try to seek out the whole letter for you Wesley

>For the purpouse of that discussion it is clearly stated that besides the " name" controversy Volta never made any remarks to  perpetuality of his  device. and that should be noted.

L'elettroforo perpetuo, detto anche elettroforo di Volta è un generatore elettrostatico in grado di accumulare una modesta quantità di carica elettrica in modo discontinuo. Ideato da Alessandro Volta intorno al 1775 durante i suoi studi sull'elettricità e citato nella "Lettera a Priestley", ha attualmente utilità didattica.

"The perpetual electrophorus, also called Volta electrophorus, is an electrostatic generator able to accumulate a small amount of electrical charge in a discontinuous way.



I have had the same  conversation  with one of my professors very long time ago, and he could not find it  as well.
So it was  turned to  2 weeks of  heavy digging .
We come to conclusion  mutually  that it was Priestley response not
Volta's response based on material  on hand.
We contacted Rosemary Lloyd PhD, University of Cambridge, UK, 1979  he was in  literature and the fine arts. 
He  was actually  just fresh,  young  and willing to help.
And he  was skilled in digging  in  that material .
Unfortunately
Even Wikipedia is not free of errors.
I do thank you for your help.

actually now I got interested. So the device is a capacitor that uses just the dielectric and does not deplete even if you charge the metal plate 100 times?

What happens if you have a diode before cap negative leg? You charge the cap through the diode and then can you just keep pulling charge of the positive leg?

How does this electrophorus pull charge from the environment so it does not equalize or deplete?

That is perfectly correct.
only and only if:
in  early version of capacitor  later called  Lynden Jar you do not touch dielectric

https://www.youtube.com/watch?v=ppWBwZS4e7A this guy does not know what he is talking about  you can skip it . (  however he is good in electronics)


OK I HAVE IT

I think I could  make  video that would explain it.

thank you, I didn't even imagine that Alessandro Volta had something to do with it and let me mention something again, we accept that a one capacitor is charged, when all molecules are polarized in the volume of the his dielectric and they are polarized by application of an electric field )
