I loved the article on the Hydrogen cars coming our way in the near future. I am confused about Hydrogen technology and am hoping you can shed light (thru e-mail or another article) on why we can’t have a hydrogen converter installed on the car directly instead of depending on Hydrogen refill stations? As I comb the internet, I see many “home-grown” versions using Brown Gas extrapolated from water via a homemade heating system. It seems safe enough and doesn’t require a user to refill at a Hydrogen station. In fact, the user only has to refill the water every other month or two. Why are we not seeing these “add on” hydrogen kits being sold now via dealerships to augment current gas engines?
