Army Research Lab discovers aluminum nanomaterial rapidly splits water on contact

Green Car Congress

Researchers at the US Army Research Laboratory (ARL) have discovered that a nano-galvanic aluminum-based powder of their design splits water on contact, producing hydrogen and oxygen. The team demonstrated a small radio-controlled tank powered by the powder/water reaction.
