Does This Thing Work? It operates on a 100 year old proven technology called electrolysis. Whenever you place two pieces of metal in water‚ and apply electricity‚ the water separates into it’s basic molecules‚ Hydrogen and Oxygen (H2O). If you look at the picture on the left‚ you will see H2O molecules connected together in their liquid form which is WATER But when you apply electricity (from your car battery)‚ the molecules separate and form a GAS (called HHO) which is a mixture of Hydrogen
