Recently a photo was made of a black hole that shoots energy jets that were predicted a long time ago [Blanford and Znajek].
Not just from the virtual particles. So what if you have small black holes like the ER=EPR suggestion? That is that an Einstein Rosen Bridge is in any place where there is entanglement. [The ER is just a different sort of black hole.] So atoms may have this same sort of energy signature. Plus that paper that suggested these sorts of jets from black holes mentions a way to harness this kind of energy.--by some kind of conductor. [That I noticed in the 1978 paper by Znajek]
