It
seems-like every day there is a new announcement in the news about automobiles
powered by fuel cells. The promises are great, since fuel cells have the
potential to very quickly double the efficiency of cars while significantly
reducing air pollution.
At the same time, there have been news
stories for decades about the problems associated with petroleum. Everything
from oil spills to ozone(臭氧) alerts to global warming gets blamed on our
dependence on fossil(化石) fuels.
These two forces are leading the
world toward what is broadly known
