The PBS program "NOVA" is running a show about the cars of the future. The brothers from the radio show "Car Talk" hosts it.
It talks all about the new technology and the ways that researchers are trying to get new cars to run MUCH more efficiently.
Here's the link for PBS so you can take a look at the program and try to find when it's going to air on your local PBS station. I've seen it twice so far.
