In 1936, on the outskirts of Baghdad, construction workers unexpectedly discovered a stone sarcophagus containing a wealth of precious artifacts. Among these, the most striking were a number of ceramic vessels, copper tubes, and iron rods. German archaeologist Wilhelm Konig speculated that these objects might represent an ancient battery. Through experimentation, Konig confirmed that these ceramic vessels could generate an electric current and could be used for electroplating. Another German archaeologist, Arne Eggebrecht, replicated these artifacts and conducted experiments that further validated this discovery. American scientists also performed similar experiments, confirming the functionality of the Baghdad Battery. Despite this, people remain cautious about the technological achievements of over 2000 years ago.
