Hello, Glen , the answer is short: No. Benjamin Franklin was one of the first men who notice that metals (or any conductors), when charged, have all of its free charges on its outter surface. Latter, Faraday did some weird experiences about electrical charge, one of them consisted in living inside an electrically charged hollow recipient for some time, and he didnít notice any evidence that the recipient was charged, because there isnít any electric field inside the metal at all. Even if you plug a wire inside a charged hollow sphere, the charges couldnít break the potential wall between the outter surface and the inside, and thereís no electrical current, otherwise Faraday could not survive to tell us about this. Furthermore, in your question you guess that we could have a permanent electrical current, even without giving more energy to the system, which proved impossible in every experience until now. Itís the perpetual motion engine, that canít exist. Hope this helps Any doubts to firstname.lastname@example.org D!
