       the following classification     of     energetically    extravagant
       civilizations:

           TYPE I:   A level "near" contemporary  terrestrial  civilization
                    with an  energy  capability  equivalent  to  the  solar
                    insolation on Earth, between 10exp16 and 10exp17 Watts.

           TYPE II:  A civilization capable of utilizing and channeling the
                     entire radiation output of its star.  The energy
                     utilization would then be comparable to the luminosity
                     of our Sun, about 4x1026 Watts.

           TYPE III:  A civilization with access to the power comparable
                      to the luminosity of the entire Milky Way galaxy,
                      about 4x10exp37 Watts.
