Abstract
Recent work has questioned whether nature can extract the rotational energy of a black hole via electromagnetic fields. Although we show that the Blandford–Znajek effect is sound, the deeper physics of the electric nature of black holes remains unresolved. Recently, King and Pringle have challenged the Blandford–Znajek mechanism for the extraction of black hole rotational energy by suggesting that the electric field near the horizon gets shorted out by the black hole’s ability to absorb charge.
