Researchers with the US Army Aberdeen Proving Ground Research Laboratory have stumbled upon an aluminum alloy that, when structured into a nanomaterial powder, efficiently reacts with ordinary water to produce hydrogen gas, that can in turn be burned to produce energy. "The hydrogen that is given off can be used as a fuel in a fuel cell," explains materials engineer and team leader, Scott Grendahl. "What we discovered is a mechanism for a rapid and spontaneous hydrolysis of water."
