Nowhere fast?

The Guardian offers an interesting, if necessarily superficial, summary of the 'state of the art' in next-generation car engines, whether hydrogen-based, more directly powered by electricity, or a modification of existing technology (biofuels).

Actually, now I've checked, it mentions much the same issues as last year, though addressing some of my doubts; specifically, that hydrogen fuel cells in cars may be zero-emission, but making the hydrogen isn't – the concept just displaces the location of pollution.
