Researchers have invented a new material that will make cars even more
efficient, by converting heat wasted through engine exhaust into
electricity.

Unclear as to the actual amount of electricity that could be
produced from an automobile>s waste heat. The cited efficiency
ratings were meaningless numbers. If such a thermoelectric
converter could entirely eliminate the alternator, that would
be a good thing.
However, TE devices no matter how much they are improved, are
still very, very inefficient--they make car engines look good.

This link might explain some of the issues..

A quick google search indicates that this is not a breakthrough, yet.
