TECHNOLOGY FOCUS - IMAGING AND COMMUNICATION - Preferred Component: The light providing device comprises light-emitting diode, and provides light having wavelength of visible light region. The system further has a heat source (108), at least one chambers (a,b), and a controlling system (106) to control transportation of solution between chambers (a,b), or controls transportation of solution from a location for electric hydrolysis reaction to a location for photolysis reaction. The chamber (a) has an electric activation device. The chamber (b) has light providing device which is fluidly coupled with chamber (a). The controlling system has a computer which automates the transportation of the solution. The light is green light-emitting-diode light.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Composition: The solution further comprises sodium ions, ion of element of group IA or IIA, and a salt. The solution comprises predetermined amount of copper ions and silver ions to regenerate aluminum ion for catalytic electric hydrolysis. The electric hydrolysis catalyst further comprises a transition metal (c2) which regenerates the transition metal (c1) to active state. Preferred Ion: The aluminum ion is aluminum hydroxide. The copper ion is copper hydroxide. The silver ion is silver hydroxide or silver oxide. Preferred Process: The solution is heated at 75-185 degrees F. Oxygen is dissociated from the catalyst reviving substance. The hydrogen generating catalyst lowers the activation energy of electric hydrolysis to 1.1 V or less. The voltage of -0.4 V to -0.9 V is applied to the solution containing hydrogen generating catalyst. The aluminum, copper and silver are ionized into the solution, by applying positive voltage to aluminum, copper and/or silver. A white precipitate is formed by applying voltage. The non-transition metal electric hydrolysis catalyst is reacted with a water molecule to form a chemical bonding with a hydroxyl group. The transition metal (c1) receives hydroxyl group from the non-transition metal electric hydrolysis catalyst, or transition metal (c2) receives hydroxyl group from transition metal (c1). The transition metal (c2) dissociates a bonded oxygen by receiving light. The light having wavelength of 350-750 nm is provided to regenerate the catalyst reviving substance. Preferred Property: The voltage applied to ionize aluminum, copper and silver is more than the voltage applied for electric hydrolysis.
