Ok, it is one of those stories where a friend of a friend made a homemade hydrogen fuel cell on his car. I don't know the complete details because the friend that I know doesn't know cars very well. He asked me how the system worked and I never heard of it. I guess from what I have heard, it is done with water, baking soda and a battery. It was hooked up in the car in the fuel or air system and now it get 40 mpg per gallon of gas with this technique.
I have never heard of this working or even heard/seen of this in any of the car forums. Unless I missed out on this somehow but usually these homemade gas saving techniques are full of shit...
Does anyone know of this or was this discussed in another thread that I don't know about?
