  • Patent number: 11952273
    Abstract: We disclose herein a viable, cost efficient method for the instantaneous production of hydrogen gas. Hydrogen gas production is increased by utilizing solar and lunar energy. The hydrogen gas is generated spontaneously by the reaction of sodium hydroxide and aluminum as corrosion occurs, forming a layer of aluminum oxide upon the aluminum. This aluminum oxide layer prevents further reaction of sodium hydroxide and aluminum, and thus no more hydrogen gas is produced. Production of aluminum oxide can be bypassed by adding acetic acid or sodium acetate to the reaction. In this reaction the products are aluminum hydroxide and hydrogen gas. Thus, we disclose herein a method that prevents of the formation of aluminum oxide by the use of sodium acetate or acetic acid, the use of iron as a catalyst, and the enhancement of the reaction using natural light.
