bwilson4web has read his Prius' cat temperature sensor in real time, and it was 600-700°C: http://ecomodder.com/forum/showthrea...ius-13288.html

I've measured my own catalytic converter's housing with an IR thermometer at 800°F, about 30s after shutting off the engine. Yay, mixed units!

Stirling engines are fun because they can operate with a very small delta-T, but I haven't seen a compact, inexpensive, powerful Stirling engine. Come to think of it, I haven't seen a Stirling engine do any work aside from rotating its own shaft. Rankine is probably more realistic.
