A steady-state source of neutrons is produced within an electrically grounded and temperature controlled chamber confining tritium or deuterium plasma at a predetermined density to effect implantation of ions in the surface of a palladium target rod coated with diffusion barrier material and immersed in such plasma. The rod is enriched with a high concentration of deuterium atoms after a prolonged plasma ion implantation. Collision of the deuterium atoms in the target by impinging ions of the plasma initiates fusion reactions causing emission of neutrons during negative voltage pulses applied to the rod through a high power modulator. The neutrons are so generated at a relatively high dose rate under optimized process conditions.

Isotopic hydrogen enrichment in a soluble metal is achieved through temperature gradient effects by applying a heat source and a heat sink to two spaced regions of the metal within which isotopic hydrogen atoms are absorbed and enclosed by a diffusion-barrier material. The temperature gradient so created forces the atoms of hydrogen in the hot region to migrate into the cold region, resulting in higher isotopic hydrogen density in the cold region. Discharge of the absorbed isotopic hydrogen is prevented effectively by the diffusion-barrier material.

A method for propelling a projectile by applying a high power pulse of elrical 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.

Method for launching projectiles with hydrogen gas

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.

A high power pulse of electrical current causes a metal conductor to expl and initiate a reaction between an aluminum or aluminum alloy powder and water which generates hydrogen gas at a high temperature and pressure. The reaction mixture is released into a second larger chamber equipped with heat exchanger which extracts useful heat energy and cools down the reaction mixture. The hydrogen gas is then separated from the solid metal oxide byproducts in the cooled reaction mixture.

Material and method for fast generation of hydrogen gas and steam

A method of propelling a projectile from a device by applying a high power pulse of electrical current to a thin metal conductor wire causing the wire to explode and disperse hot spots of molten metal throughout an aluminum fuel powder/water mixture which reacts to generate hydrogen gas at high pressure in a chamber. The hydrogen gas is used to push the projectile from the device.
