Curious if the energy pay off worth it to the civ to be revealed.. seems risky.

such a civilization would much more about the possible threat than we do.

Could also be.. a galactic honeypot? Catch someone's hand in the cookie jar?

I guess a black hole would work; not clear that there's always one around, and why not just radiate? Non-isotropic works.

But non-isotropic is inefficient in a Carnot sense.

Yes, if the Galaxy is a hostile place, one might hide. Not sure how one would know such a thing in advance, though.

Don't understand; if it's coming out over 2pi it's isotropic. If not, it's inefficient. Pipes/chimneys don't change anything.

I don't think so. It's the properties of the waste heat photons far away that matters. They have to have high entropy/isotropy.
