The Ringing Bell

Since 1840, an experimental electric bell has been ringing almost continuously in the foyer of the Clarendon Laboratory at the University of Oxford. Called the Clarendon Dry Pile, the device is made up of two voltaic "dry piles" connected with an insulating layer of sulphur; the piles are connected, in turn, to two bells. The Guinness Book of Records deems the bell the "world's most durable battery," though it will eventually stop ringing when either its clapper wears out or its electrochemical energy is exhausted.

Yep and back in Edisions day of early radio and electricity they made Earth batteries that could power transmittion stations and home lights for most a century but required a garden size patch of buried iron parts. Sometimes I find someone spine condition is a elctro-nerve reflex from metal tooth fillings of different compostitions acting like a battery till removed. Tesla and others have stuck antennas up in air on simple cicuits to get continuos power for free.
