Driving a Rocket Fueled Car: 500 Miles at 400 Degrees Below Zero

The physical and chemical properties of hydrogen make its use superior to fossil fuels. Producible virtually anywhere from using electricity, it is a simple, non-toxic molecule that can generate electricity or power vehicles cleanly, efficiently, and even silently, if we choose. Development of hydrogen automobiles has been hindered, however, because hydrogen is much more difficult to store than gasoline. Gene Berry, Research Scientist at Lawrence Livermore National Laboratory and high school teacher Dean Reese, explore the need for alternatives to gasoline and what role hydrogen might play.
