Interesting Fact # 797 - Hydrogen Powered Cars

For years BMW has been refining its dual-fuel (hydrogen/gasoline) technology. They have now developed the mono-fuel Hydrogen 7, which runs solely on hydrogen.

(According to Argonne National Laboratory it is "one of the lowest emitting combustion engine vehicles that have been manufactured." This is great news! Until you read the Spiegel that is, which says that the hydrogen dispensed at filling stations is generated primarily from petroleum and natural gas. So, the shiny new car puts about as much strain on the environment as a heavy truck with a diesel engine.)
