This small but very powerful electrolyzer produces gas that increases the fuel mileage of your car. The elctrolyzer runs on baking soda (4 volts/cell) and produces hydrogen. Electrolyzers in general are machines that uses a direct electric current to drive a chemical reaction that would otherwise not occur on its own.
This particular HHO electrolyzer can run a car, and if you double the number of plates you can increase how well it works and also use lye. Purchase the stainless steel sheets from your hardwood supplier.
