Hydrogen-powered fuel-cell vehicles

In Takanezawa, Japan, on June 16, 2008, Honda Motors produced the first assembly-line FCX Clarity. More efficient than a hybrid vehicle, the FCX Clarity combines hydrogen and oxygen from ordinary air to make electricity. The vehicle does not emit any pollutants and its only byproducts are heat and water. The FCX Clarity also has an advantage over hybrids in that it does not require a rechargeable battery and the use of electricity. The lack of hydrogen filling stations throughout the U.S. will keep production volumes low.
