Converted is much more than an installation manual - although it serves as that as well. You will learn everything you need to know to take water and put it through a process called electrolysis to separate the hydrogen from the oxygen as you drive. It silently flows into your vehicle's combustion system and give better economy, a quieter cooler engine and less engine wear. This process, properly installed and tuned, is safe and effective because it creates hydrogen on demand and radically improves the fuel economy of a vehicle. In language understandable by virtually anyone the book explains the process. There are many photos and illustrations to guide you through. You can purchase the parts you need on your own but Richie has done all the work for you and will send you a complete kit at a very reasonable price if you decide to go ahead and save money while you reduce the pollution in the environment.
