In this video I'm building a homemade HHO dry cell generator form scrap, this is the first dry cell generator I have built and I'm am not a professional. The only materials I had to purchase was the fasteners cost about four dollars. An HHO generator is just a unit which separates Hydrogen and Oxygen from water using electrolysis. Electrolysis is a very simple process learned in high school science class with a Hoffman Apparatus. They call these things HHO generators now because the term HHO was adopted from the masses. The gas that comes out of these units are a mixture of Hydrogen and Oxygen, "Oxyhydrogen" when water and a catalyst is used. Oxyhydrogen was used in the 1800's for lighting " Lime Light" .
