  To explain the extremely high energy release, $>10^{53}$~erg, suggested by
the observations of some Gamma Ray Bursts (GRBs) we propose a new energy
extraction mechanism from the rotation energy of a Kerr-Newman black hole (BH)
by a massive photon field. Numerical results show that this mechanism is stable
with respect to the black hole rotation parameter, $a$, with a clear dependence
on the BH mass, $M$, and charge, $Q$, and can extract energies up to $10^{54}$
erg. The controversial "energy crisis" problem of GRBs that does not show
evidence for collimated emission may benefit of this energy extraction
mechanism. With these results we set a lower bound on the coupling between
electromagnetic and gravitational fields.
