This IS NOT the case of the cavity under discussion, because its
temperature increase with the permanent supply of energy, until it's
destroyed, partially or entirely.
Why should the foil box not radiate away energy as its temperature
rises?
Forget the innards. I don't care whether the reflectance is 0.85 or
0.99999. Those numbers only dictate the power levels reached within
the cavity.
What happens to the exterior surface of the box?
