Car manufacturers have spent a millions and millions to develop a fuel efficient new generation engines. In the not too distant future hydrogen powered cars and trucks will be available. This fuel is the ultimate "green" alternative as only water vapor is produced.

One of the leaders, BMW Automobiles estimates it will take between ten and fifteen years for hydrogen power to become available to the general public. And BMW takes the future use of hydrogen as a power source seriously. They are working with fuel companies in setting up liquid hydrogen fueling stations in the United States and Europe.

Jim O’Donnell, of BMW UK said, “The arrival of our (BMW) Hydrogen 7 cars could not have come at a better time. Politicians, business leaders, the media and consumers are engaged in healthy debate on the future of energy supply and use. Meanwhile, the automotive industry is committed to cleaner motoring, with a host of possible solutions available today and being developed for the mid- and long-term. BMW is at the core of the future of motoring with tremendous developments in petrol and diesel engines, hybrid powertrains and hydrogen technologies.”

Here in In California they propose to have a Hydrogen Highway in place by 2010.
