Abstract
A method for propelling a projectile by applying a high power pulse of electrical current to a metal fuel element (of Al, Al--Li, or Al--Mg) causing the element to explode dispersing molten metal fuel into water with which it reacts to rapidly generate hydrogen gas at high pressure; the hydrogen gas is used to push the projectile. After the peak current is reached, an inductive electrical energy source drives the electrical current into the molten metal fuel/water mixture thus driving the reaction to completion.
