In 2003 we listened to CARB and the "Autos" depend-on and,
respectively, assure us that fuel cell-powered transportation was
just five years away for "thousands" quantities and really serious
production would happen by 2015. We argued then, as now, that as
transportation necessarily becomes more electrified—in order for
California and the nation to comply with international treaties to
reduce combat global warming—it is essential that we not be
burdened by the fuel cell's inefficient use of electrical power,
i.e., from hydrogen manufacture to power at the vehicle's wheels
requires very nearly 4 times the electrical power of electric
vehicles. At present, this is a fundamental fact of hydrogen
production and use.

Of course other practical problems, e.g., cost, durability,
complexity, lack of infrastructure, also argue against the fuel
cell approach. 

Remember too, that we are not simply arguing about the ultimate
best technology. Rather, we are arguing about what can be done
almost immedaitely to improve air quality and reduce the
production of GHGs.We lost valuable time in 2003, lets not fail to
produce a practical answer in march 2008.

Thank you.
