  Searching for these  structures  is  the  domain  of millimeter wave
       astronomy.  For the 300 Kelvin technology, the maximum emission
       occurs in the infrared region (15-20 micrometers) and searching is
       accomplished with infrared observations from Earth and space.  The
       existing radio surveys of the sky  (lambda  =  6 centimeters (cm) on
       the ground and lambda = 3 millimeters (mm) for the Cosmic Background
       Explorer (COBE) satellite) place an essential limit on the abundance
       of ETC 3   Kelvin   technology.   The  analyzes  of   the   Infrared
       Astronomical Satellite (IRAS)   catalog  of  infrared  sources  sets
       limitations on the abundance of 300 Kelvin technology.

       Electromagnetic radiation carries  virtually  all the information on
       which modern astrophysics    is    built.     The   production    of
       electromagnetic radiation is directly related to the physical
