^^^Bingo, and in response to the many statements concerning the grid and where the power comes from. Yes, the majority of power in the US today still comes from carbon emitting fossil fuel plants. This is quickly changing however, much more quickly than alternative fuel powered vehicles are being developed. That being said, hydrogen powered cars have always concerned me, because our current means of producing hydrogen takes a lot of power initially. So yea, the byproduct of a hydrogen car is water, but all the power it took to produce that hydrogen more than likely came from a fossil fuel, not to mention all the power it took to transport that hydrogen to where it needed to go. It just seems so much simpler to me to not waste time and energy storing the energy in chemical mediums. It would be so much more efficient to store it in a battery as electricity. This way instead of building a whole new infrastructure, we would just have to continue to alter the method of deriving our electricity right from the source.

Sorry for the novel, its just that this is a matter of great interest to me.
