In this published note I attempt to sketch my understanding of the universal working scheme of all the astrophysical jet sources, or ‘bipolar flows’, on both stellar and galactic scales, also called ‘microquasars’, and ‘quasars’. A crucial building block will be their medium: extremely relativistic e±-pair plasma performing quasi loss-free E × B-drifts through self-rammed channels, whose guiding equi-partition E- and B-fields convect the electric potential necessary for eventual single-step post-acceleration, at their terminating ‘knots’, or ‘hotspots’. The indispensible pair plasma is generated in magnetospheric reconnections of the central rotator. Already for this reason, black holes cannot serve as jet engines.
