Yes a lot hotter for the exhaust system.  As if it was not
hot enough.
Is Inconel alone could sustain that amount of heat?

WOW, I'll bet their engine will even run on the Free BS they are putting out.

Technical Ceramics offers solutions to many of the problems we now face.  But, it Ain't Cheap.  There URL looks like a High Tech Proposal for US Gov. Funds for a project that doesn't have to work.
