Disclosed herein is a method for generating energy by using exothermic reaction of metal, comprising the steps of reacting an oxidant containing mostly water with combustion substances mainly containing light metals to generate hydrogen; reacting generated...

Disclosed are an adiabatic engine, an engine capable of reusing exhausted energy, and a high pressure jet assembly. The adiabatic engine has: a cylinder (10) having an inner side surface, on which the adiabatic member (12) is formed extending longer than a...
