If you're a fan of green car technology, then you might wonder how to explain all the possibilities (hybrids, biofuels, electric vehicles, plug-in hybrids, diesel engines, etc.) to someone who doesn't know from cellulose-based ethanol. If you've got a friend you'd like to bring in to the green car conversation, a write-up over at Political Cortex might save you time in explaining the general situation with green cars and what the possibilities are for the near future. The article goes through all of the engine types listed above, as well as slightly more complicated topics like Homogeneous Charge Compression Ignition. It is a well-written introduction to the world of alternatively powered cars. It doesn't tell us exactly what the car of the future will be, but it certainly lays out what the options are.
As an added bonus (at least for me as editor of AutoblogGreen): there are a lot of nice links back to this site once readers are done over there.
