Fuel Cells. When the automobile was mass produced by Henry Ford it seems to me that there really weren't or couldn't have been to many gas stations around either. I don't think the gas stations were around before most of the ICE autos. Don't you think if Fuel cell vehicles were around by being mass produced the energy companies wouldn't seed up centers to distribute hydrogen. Also don't forget making hydrogen by using wind and electrolysis not just with solar.
Hydrogen will be made the most cost effective way, from nat gas. So, where we getting all this nat gas and what do we do with the carbon dioxide that results from this process. Per Donald Anthrop "a transition from gasoline to hydrogen would nearly double net greenhouse gas emissions attributable to passenger vehicles" http://www.cato.org/pub_display.php?pub_id=2608
