If you’ve gone any time without electricity, you know that batteries are really one of the most wonderful things in the world. The Baghdad Battery shows that battery power was sought after even thousands of years ago. The Battery is a set of 3 artifacts discovered in Khujut Rabu outside Baghdad, Iraq. Thought to be 2,000 years old, the set has a ceramic pot, a tube of one metal, and a rod of another. When filled with vinegar or similar liquid, the pot produces about 1.1 volts. There is no written record as to the exact function of the jar, but the best guess is that it really was a type of battery.
