John Pearce on 10 May 15"Batteries are so ubiquitous today that they're almost invisible to us. Yet they are a remarkable invention with a long and storied history, and an equally exciting future. A battery is essentially a device that stores chemical energy that is converted into electricity. Basically, batteries are small chemical reactors, with the reaction producing energetic electrons, ready to flow through the external device. Batteries have been with us for a long time. In 1938 the Director of the Baghdad Museum found what is now referred to as the "Baghdad Battery" in the basement of the museum. Analysis dated it at around 250BC and of Mesopotamian origin."
