Earlier in my post I was pointing to the convince factor from a consumers point of view of hydrogen as a "fuel" (it's actually a energy storage medium but i'm too lazy to type that every time) opposed to batteries as the future of on board energy supplies. But even though they are different, all you're really pointing out is efficiencies of the two methods. That's kind of like comparing a normal ICE to a hybrid (or electric cars with an on board generator, that would probably be more accurate comparison). One only uses internal combustion, the other uses a combination of combustion and electricity. Both consume some amount of the same kind of fuel.

If we're talking about hydrogen as a potential fuel source of the future then why should we distinguish the two different methods?

Because fuel cells being ~10x more efficient than ICE means the infrastructure and production rates required for H2 will be very different. A 100 mile range ICE would require a lot more fuelling stations than a fleet of 500 mile range FC cars, for example.

By the way, Toyota claims they will have a fuel cell model available in 2015 - for a mere $140,000 (and will probably lose money at that price).

Anyone putting in a deposit?

I don't know, an all wheel driven, by 4 in-wheel electric motors....

For the doubters of EV and performance.

John "Plasma Boy" Wayland and his White Zombie Datsun have cracked the 11-second quarter-mile plateau, with a record time of 10.258 seconds and a speed of 123.79mph.

Wayland says his Zombie can go 100 miles on a charge. "We have the same range as a Nissan Leaf, but we have acceleration that's better than the Bugatti Veyron," he said, referring to the vehicle known as the fastest road-legal car in the world.

He attributes the faster times and longer range to a new lithium manganese cobalt polymer pouch battery from Dow Kokam. He also has boosted the size of the White Zombie's electric motors from 772lb-ft of torque in 2009 to 1,250 today.

"We are still the world's quickest-accelerating street-legal electric car," Wayland says. "And we plan to run a nine-second quarter-mile."
