"The future of fuels for transportation may ultimately be hydrogen, the most widespread element in the universe. (Yes, there is a lot out there, in here, and in between, but a problem is getting it to be freed-up from other elements, as in separating the H2 from the O.)    Companies like BMW have been working on hydrogen powered vehicles for a number of years."^^<http://www.w3.org/2001/XMLSchema#string>
