Researchers have developed an aluminum alloy that could be used in a new type of mobile technology to convert non-potable water into drinking water while also extracting hydrogen to generate electricity.
Such a technology might be used to provide power and drinking water to villages and also for military operations, said Jerry Woodall, a Purdue University distinguished professor of electrical and computer engineering.
The alloy contains aluminum, gallium, indium and tin. Immersing the alloy in freshwater or saltwater causes a spontaneous reaction, turning the water into steam and generating hydrogen and aluminum tri-hydroxide until the aluminum is used up. The hydrogen could then be fed to a fuel cell to generate electricity, producing potable water.
