The Riddle of Baghdad's Battery

Jodrell writes "The BBC has an interesting article about a 2,200 year old battery discovered in Iraq in 1938. It is basically a clay pot containing a copper/iron core immersed in an electrolye solution (probably acidic vinegar). The article talks about how this priceless artifact as well as many others, from the same civilisation that invented writing and the wheel, could be threatened by the impending war."
