2,000-Year-Old Electricity

“If you thought electric bulbs and batteries were modern European inventions, here is something to put that fact to question! A 1936 excavation of some 2000-years-old ruins in an ancient Baghdad village unearthed a small yellow clay vase about 6 inches in height. It had a copper-sheet cylinder lining within it that measured 5 x 1.5 inches… Ever since its recovery, several possibilities have been suggested by experts. Wilhelm König, the German archaeologist brought forth a startling idea that the clay pot could well be a form of electric battery. Following his theory, a Massachusetts based engineer Willard F.M. Gray created a model of this battery in 1940, filled it with copper sulfate solution and proved that it could produce electricity.” w/ photos + video
