Hydrogen-Fueled Race Car Showcases Future Technologies

A record-breaking race car powered by a hydrogen fuel cell offers proof that development of alternative-energy vehicles is well under way–and that widespread use of eco-cars might be on the horizon.

The car, called the PAC-Car II, set a world record in fuel efficiency earlier this year when it achieved the equivalent of 12,665 miles a gallon (5,384 kilometers a liter) of gasoline.
