Abstract: 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.

Abstract: The present invention relates to a gas lighter with a roller-rotation restraining part, extending toward a roller from one side of a top surface of a cap for surrounding a nozzle of the gas lighter so that the roller-rotation restraining part is caught by and brought in contact with the roller. Thus, a certain rotation-restraining force is added to the rotation of the roller by means of the roller-rotation restraining part which is caught by and brought in contact with the roller during the rotation of the roller for ignition to increase a finger grasp force required for the ignition of the gas lighter through the rotation of the roller, thereby being capable of preventing an accident, should the lighter get into the hands of a child.
