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.

Claims (10)

1. A method for producing hydrogen gas comprising combining solid aluminum, sodium hydroxide, and acetic acid with a metal selected from the list consisting of iron, copper, tin, gold and platinum in a reaction, and exposing said reaction to natural light, wherein hydrogen gas production is increased by such exposure and wherein the increased production is as compared to a reference reaction that is not exposed to natural light but otherwise the same, and wherein said metal provides a surface for hydrogen gas production separate from said solid aluminum, further wherein the hydrogen gas production takes place and remains at or above room temperature.

2. The method of claim 1 wherein said acetic acid prevents the formation of aluminum oxide and forms aluminum hydroxide.

3. The method of claim 1 wherein said metal serves as a catalyst for the reaction.

4. The method of claim 1 wherein said light passes through a transparent color Mass container.

5. The method of claim 1 wherein said light is daylight, and said daylight passes through a transparent container.

6. The method of claim 5 wherein said daylight passes through a transparent colored container.

7. The method of claim 5 wherein said daylight passes through a red color impregnated transparent container.

8. The method of claim 1 wherein hydrogen gas production on the surface of iron or other metals such as copper, tin, gold or platinum in the reaction depends on the physical touching of the metal surface with said solid aluminum and complete submergence in sodium hydroxide and acetic acid solution.

9. A method for enhancing the production of hydrogen comprising combining solid aluminum, sodium hydroxide, sodium acetate and iron in a reaction, and exposing said reaction to natural light, wherein hydrogen gas production is increased by such exposure and takes place and remains at or above room temperature, further wherein the increased production is as compared to a reference reaction that is not exposed to natural light but otherwise the same, and wherein said iron provides a surface for hydrogen gas production separate from said solid aluminum.

10. The method of claim 9 wherein said sodium acetate prevents the formation of aluminum oxide and forms aluminum hydroxide.
