This Letter reports on 3-dimensional simulations of Kerr black holemagnetospheres that obey the general relativistic equations of perfectmagnetohydrodynamics (MHD). In particular, we study powerful Poynting fluxdominated jets that are driven from dense gas in the equatorial plane in theergosphere. The physics of which has been previously studied in the simplifiedlimit of an ergopsheric disk. For high spin black holes, $a/M > 0.95$, theergospheric disk is prominent in the 3-D simulations and is responsible forgreatly enhanced Poynting flux emission. Any large scale poloidal magnetic fluxthat is trapped in the equatorial region leads to an enormous release ofelectromagnetic energy that dwarfs the jet energy produced by magnetic fluxthreading the event horizon. The implication is that magnetic flux threadingthe equatorial plane of the ergosphere is a likely prerequisite for the centralengine of powerful FRII quasars.
