Question: Why not create the Hydrogen as you drive with electroalsys(SP?) of water? The power for that can come from systems similar to the regen brakeing on current hybrids. This would eleminate the need for the \"infrastructure\" everyone keep complaining about. Second a small discrete solar cell that is designed to \"fit\" into the style of the car can power the electroalsys when your not driving. I.E. when the car is sitting on the parking lot all day at work. While I know that will never supply all the fuel it is something that would not be otherwise. Just my thoughts.
