How to Build a Hydrogen Generator
You can build a hydrogen generator out of some things you have around your house. In stainless steel you need: light switch covers, bolts, 2x12x1/16 plates. You also need baking soda, distilled water, pvc pipe, hose, wire, 12 volts and a 10 amp regulator. When these things are put together they make a pretty decent generator.
