Sometimes we have to step out of the box. The earth used to be flat, going to the moon would be impossible.
One thing for sure, right now at this point, nothing can replace gasoline vehicles. This is simply critical thinking. We do not produce enough energy nor the infrastructure to supply 300 million vehicles other than gasoline at the moment.
Look at latest news and this is just a pinhead of things taking place, not covered here is nuclear production of H2 and a range of other methods. To think that in 50 years lithium battery cars will be the method I think short sighted... sadly I wont be around to know so you wont be able to prove me wrong *LOL*

Im certainly not saying that H2 is the future as much as I am saying we need to step out of the box in our thinking. If you really think about it, the only ones in this world who create something are those 1 in 10 million or more. I think it's more far fetched to think the electric grid is going to supply the energy for 300 million vehicles... and then just the national security at stake in relying on a sole concentrated power source as power plants.
I wish I would be alive in 50 years but even then, those people in 50 years will be looking to advance to something else.
