I'm trying to convert an old 12 Volt car battery into an HHO generator. I want to achieve electrolysis of water using a dead battery as the vessel. A battery seems to have all of the necessary components: water tight case, electrodes, connections, and vent holes. I've witnessed other devices that achieve electrolysis (using titanium and stainless electrodes and a little baking soda) and then hold a small charge...so I figured "why build a battery...why not use a battery? Unlike everyone else doing this, I'm not trying to fuel a motor or improve gas mileage. Instead, I want to generate a small quantity of HHO on demand, run it through a 1/8 plastic tube and try to achieve/test a small flame with a very clean burn (ultimately for use in a very light manufacturing process).
