Search for Strongly Polarized Radio Emission from E.T.I., and an Optimist Approach to the Great Silence (Fermi's Paradox) [chapter]

J. P. Vallée
1985 The Search for Extraterrestrial Life: Recent Developments  
A summary is made of a program to scan slowly a band of sky in search of strongly linearly polarized radio signals from E.T.I, communication relays. Despite this and numerous other observational searches, no signals have been found. An optimist approach to this great silence (Fermi's paradox) is developed.
