The first and only person to break the sound barrier in a car has his eye on another speed record. British driver Andy Green set the land speed record for a diesel-powered car 20 years ago at Utah’s famous Bonneville Salt Flats. Green returns to the lunarlike landscape Tuesday to try to beat that 350.092 mph mark, this time with a hydrogen-powered car. The retired Royal Air Force fighter pilot aims to showcase the power of hydrogen as a clean-energy alternative. But hydrogen power is only as clean as its source, and the vast majority is currently produced from fossil fuels.
