Do (micro) black holes extract energy from the vacuum?

Is there a future possibility to extract energy from the vacuum?
Is harnessing ball lightning perhaps the solution for our energy problem on Earth.
One of the most involved persons on this issue is Jack Sarfatti.
His latest paper is the next one:
The emergence of gravity etc. etc. Authors: Jack Sarfatti, Creon Levit (Submitted on 31 Jan 2009) http://arxiv.org/abs/0902.0032
Abstract: We present a model for the origin of gravity, dark energy and dark matter: Dark energy and dark matter are residual pre-inflation false vacuum random zero point energy (w=-1) of large-scale negative, and short-scale positive pressure, respectively, corresponding to the "zero point" (incoherent) component of a superfluid (supersolid) ground state. Gravity, in contrast, arises from the 2nd order topological defects in the post-inflation virtual "condensate" (coherent) component.
