I believe the "hydrogen highway" is an effort to preserve the gasoline distribution system by switching from one fuel to another.
If autos become electric then the need for gas stations and trucks to distribute gasoline and gasoline tank farms is also eliminated. Not that batteries have the potential to hurt any gasoline or alternative fuel as of right now.
If cars ran on milk, exxon would own a lot of cows.
I suppose it's because of the perception that we'll become even more "dependent" on middle easterners for our supply until we're forced to surrender all our economic and sovereign interests to the OPECker Princes, or some such.
I believe that's a concern, or perceived vulnerbility that is completely overblown only because the liberals/media/one-worlders keep up their dumb din of "no blood for oil!" I do NOT believe we'll run out of oil and do not believe all the scary scare tactics that people like Art Bell and Arnold Schwarzenegger are so easily bamboozled by. That's what I believe.
I refuse to believe what a whole bunch of negitivistic anti-American and anti-capitalistic leftist WANT everybody to believe... That we're always on the eve of destruction!!!
