a method and system for generating high pressure superheated steam on demand that uses nano - sized aluminum particles to allow oxidation and heat generation using photonic initiation . this invention uses the unique properties of nano - sized aluminum either alone or with other energetics to provide the needed heat to quickly vaporize and superheat water directly in either a flowing water or static water environment to produce steam as needed . due to its compact design it can be used in new or existing steam applications . this steam use may be any application that needs an on demand high pressure steam supply . applications include steam catapults , boost steam for turbines , steam cleaners , surge power for powerplant turbines and any other use .
