“Researchers at Indiana’s Purdue University have further developed a recently described technology that can break down water directly into hydrogen and oxygen without input power.
It is based on the idea of taking an aluminum/gallium alloy and flowing water across it. The aluminum splits the water into hydrogen and oxygen without any input power. Basically, the oxygen is drawn to the aluminum and the hydrogen bubbles away to be collected. The gallium is present to prevent normal oxidation on the aluminum’s surface, thereby keeping the source free from almost immediate contamination which normally occurs on aluminum during electrolysis. It’s an interesting use of the material because gallium is even a waste byproduct of aluminum manufacturing.”
