Investigation of the Light Emitters in the Aluminum - Water Reaction
… aluminum wires were successfully ignited under water at various pressures, but a complete, self sustained reaction of the aluminum was not achieved. The spectra measured in this study are qualitatively the same at the different pressures, but the intensity increases with pressure. Principle …

An in-situ interdiffusion method for harvesting energy from an aluminum-water reaction
Autonomous underwater vehicles (AUVs) are indispensable for countless underwater tasks but are currently limited in their range and endurance by the energy density of their battery packs. Aluminum is an ideal energy source for AUVs because it exothermically reacts with water and is two orders of …
