re: Some cheery fuel cell news...
Unless we move into hydrogen, batteries, flywheels, or some other method of moving our vehicles around, non-fossil methods of generating power like nuclear, solar cells, or wind power aren't going to make much of a dent in our oil use.
So a practical hydrogen car is still a step forward.
I don't think there's enough biodiesel around for ALL the cars. And biodiesel still spits CO2.
