This experiment proved that electric batteries were used some 1,800 years before their modern invention by Alessandro Volta in 1799. It also seems that the use of similar batteries can be safely placed into ancient Egypt, where several objects with traces of electroplated precious metals have been found at different locations.

BEIJING , China -- A team of Chinese scientists is to head out to the far west of the country to investigate a mystery pyramid that local legend says is a launch tower left by aliens from space. Nine scientists will travel this month to probe the origins of the 50-60 meter (165-198 ft) tall structure -- dubbed "the ET relics" -- in the western province of Qinghai, China's state-run Xinhua agency said on Wednesday. The mystery pyramid sits on Mount Baigong, has three caves with triangular openings on its facade and is filled with red-hued pipes leading into the mountain and a nearby salt water lake, Xinhua said.
