Doesn't such a Neutrino Pump require a Maxwell's Daemon at it's core? I
hear (this) universe is short of them... perhaps the parallel ones where
our neutrons are going missing has some to spare?
Sounds nearly like the story in "The gods themselves"
from Isaac Asimov, I have read it last week in the holidays.
Time to setup a Neutrino pump ? :-)

Neutrons escaping to a parallel world? June 15, 2012
In a paper recently published in European Physical Journal C,
researchers hypothesised the existence of mirror particles to explain
the anomalous loss of neutrons observed experimentally.
The existence of such mirror matter had been suggested in various
scientific contexts some time ago, including the search for suitable
dark matter candidates.
Theoretical physicists Zurab Berezhiani and Fabrizio Nesti from the
University of l'Aquila, Italy, reanalysed the experimental data
obtained by the research group of Anatoly Serebrov at the Institut
Laue-Langevin, France.
It showed that the loss rate of very slow free neutrons appeared to
depend on the direction and strength of the magnetic field applied.
This anomaly could not be explained by known physics.
Berezhiani believes it could be interpreted in the light of a
hypothetical parallel world consisting of mirror particles.
Each neutron would have the ability to transition into its invisible
mirror twin, and back, oscillating from one world to the other.
The probability of such a transition happening was predicted to be
sensitive to the presence of magnetic fields, and could therefore be
detected experimentally.
This neutron-mirror-neutron oscillation could occur within a timescale
of a few seconds, according to the paper.
The possibility of such a fast disappearance of neutrons -- much
faster than the ten-minute long neutron decay -- albeit surprising,
could not be excluded by existing experimental and astrophysical
limits.
This interpretation is subject to the condition that the earth
possesses a mirror magnetic field on the order of 0.1 Gauss.
Such a field could be induced by mirror particles floating around in
the galaxy as dark matter.
Hypothetically, the earth could capture the mirror matter via some
feeble interactions between ordinary particles and those from parallel
worlds.
