Yea
But I really hope someone makes skudderite 800-900K TEGs commercially available soon, they seem to have slightly better Z than most materials now, and something that can directly interface with exhaust more or less could be very effective. 1-2 pounds of TEG, a few more pounds worth of aluminum waterblock, a 2 pound radiator, hooked up to the existing cooling system, a DC-DC converter to prevent it from sapping power before the engine heats up, could easily provide almost all of the car's electrical requirements.
Oh and speaking of waste, I noticed that some of the companies doing TEGs were using a noble gas in a heat exchanger on the exhaust, rather than bolting the TEGs directly...what the hell? Did they do that to intentionally add weight and cost and make it seem unfeasible?
