I want to know if there is a Hydrogen based bolt on system or component that I add to my inline 6 in my Jeep? Hydrogen technology has been around but before it goes mainstream, I am sure most modern engines can be equipped with a system that is partially fueled by hydrogen thus a less dependence on fossil fuels and increased MPG. It will be 50 years before hydrogen engines/fuel becomes mainstream so until then or until I die, I would like to see if I can modify my current gasoline engine and combine it with a possible bolt on system.
