An interesting short piece in Wired's Autopia discussing Nissan's 2007 Altima Hybrid.

This is interesting because it is available now and at a reasonable price, and so the impact on company sales can be measured in the short term. I'm always wary of announcements involving technologies (let alone mass production) that are years away.

This harks back to the idea of bridge, or transition, technologies. Companies that are finding ways to make money from existing technologies while still keeping eye on promising future technologies are worth keeping on the radar.
