Hmm?... but what about heat conduction via carbon strands in

it'd be there.

It needn't be zero, it need only be less than the heat transmitted
by radiation.

There are already inconel radiation baffles behind the RCC to reduce
the radiative heat transfer.

I'll note that carbon aerogel would have the problem of eroding
rapidly if exposed to high temperature air. A combination carbon/SiC
aerogel might get around that problem.

Your replies have been quite interesting, Paul, and I don't know
how it would work out. My original aerogel response was not meant
seriously, but the subject makes for interesting reading and
research

Now I must go and beat up on Zoltan again...
