Scientists develop air-powered battery

In a possible first step toward a new source of energy, researchers in China have developed a battery system that can capture and generate electricity from atmospheric nitrogen.

Nitrogen is the most abundant gas in Earth’s atmosphere, and could provide an almost limitless source of energy if it could be harnessed, which a research team at the Changchun Institute of Applied Chemistry, part of the Chinese Academy of Sciences, seems to have done, at least on an experimental scale.
