Getting a charge out of wasted automobile heat

Looks like one can place say a 100 of 2x2in 100wt $10 Peltier coolers from AMZN around the exhaust and get 10kw.

and that doesn't chemically interfer with the catalyzer?

you would place them onto external surface of the exhaust pipes. As the meaningful location would be the upper portion of the exhaust, upstream of the catalyzer, it would decrease the temperature of the exhaust coming to the catalyzer, so it may potentially affect it work when engine is at low-power.
