The tungsten lattice's ability to suppress infrared transmission bodes
ill for those searching the skies for Dyson Spheres and Matroishka
Brains:

"Experimental results showed that a large photonic band gap for
wavelengths from 8 to 20 microns proved ideally suited for suppressing
broadband blackbody radiation in the infrared and has the potential to
redirect thermal excitation energy into the visible spectrum."

This implies that such macroengineering structures, if equipped with
this technology, would be capable of stealthing themselves entirely
within the cosmic background radiation. Such entities would recycle
their waste heat round and round within the structure, cooling their
black body temperature significantly.
