UPDATE: Unfortunately, this idea seems to be refuted. Interesting thinking though, and hopefully some of this will work in some contexts. As far as I know there are plans to install it in a few places in the developers' hometown of Sandpoint, ID.
Here is a great example of the kind of forward thinking that this site promotes. Solar Roadways! Apparently this engineering couple has devised a material that can both be a good solid driving surface but also contain solar panels to generate power; heating elements to keep ice off in the winter; and LED lights to warn of danger, change road lane configuration, etc. It can be maintained much more easily than existing roadways.
