Zeroing Out Pollution

A new technology—fuel cell vehicles—promises clean and efficient travel for the 21st century, and these cars and trucks could soon be on the roads of Asia, Europe, and the United States.

The mobility that motor vehicle travel has brought to millions over the past 100 years has also carried unfortunate side effects. One in four Americans now breathes unhealthy air, fossil fuel emissions are having a measurable effect on the Earth's climate, and oil imports are approaching their highest levels in US history. Fuel cell vehicles can help mitigate these problems through their high efficiency, zero emissions, and use of nonpetroleum fuels.
