Abstract

A metal fuel for producing power for propulsion is disclosed. The fuel is made up of a metal core, a metal barrier and an oxidizer layer. The combination of materials disclosed provides a means for melting the metal core so that it can be oxidized in an exothermic reaction to produce power. The metal fuel may also be stabilized with respect to auto-ignition by adding a binder layer. A method for producing the metal fuel is also described herein.
