Potatoes work as batteries in this clock, possessing enough moisture and ions to be electrically conductive.  A potato battery is a type of electrochemical cell, converting chemical energy into electrical energy. The potato conducts electricity, and also keeps the zinc and copper ions separate so that the electrons in the copper wire move, generating current.
