I'm doing this calcuation based on an average exhuast-side junction temperature of 150C, and cold side temp of 50C. I think solar power would be cheaper.

I doubt I could run on a deep cycle, as i'd have to go 2-3 hours of driving between charges. If it get a stormy day, or get stuck in traffic for an extra two hours, i'd need a LOT of juice.
Check this:

I think even if you only generated say, 50 watts on the highway, you'd extend the drive time of your deep cycle batteries by a large margin. This based on Daox and MetroMPG recent testing.


EDIT: If i had a bit of extra cash.. i'd be building something fo sho. Perhaps after i move into my new house. I'm totally qualified to build something like this!
