On the way to work this morning I saw a F-350 Ford van that claimed to be a hydrogen-hybrid powered. I thought that it was interesting that the person had to advertise this on their van. I guess they were advertising those HHO kits. The jury is still out on those HHO kits on if they do what they claim, or are even good for your car long term. I think I will put signs on my car that says its potato powered.
