'Hydrogen highway' touted by premier

Another report suggests the hydrogen highway could even stretch all the way to Los Angeles by the 2010 Games.

Campbell says he wants to use the Olympics to promote hydrogen energy. And he has called on other countries hosting international events to follow suit.

"If we take that critical mass of global events that bring people together, and show them the new uses of this new energy source in transportation and moving people around, I think we may find the critical mass of activity that breaks that technology through."

Campbell also says there are plans to build an environmentally-sustainable Olympic athletes village.
