I am curious as to the general opinions to the future of fuels and the future of vehicles...
It looks like right now...Hydrogen... with many other possibilities...

How long do you think it will be before alt' fuel cars are on the road and comprising the majority of the market?

Do you think, eventually, that gasoline fueled vehicles will be eliminated? If so, how many years...50, 60, 100, 150??
Without any political battles...I was just wondering what everyones take was on this...
Thanks...
Mike
