The backside de-loading scheme seems to have good rationale within
the deflation fusion model. The problem is to achieve it in a
practical way.
The key is establishing a back-side diffusion barrier, and using the
right cross-barrier potential in order to match the de-loading and
loading rates so as to sustain high hydrogen fugacity. It is also an
objective to provide a high electron charge density immediately
opposite the de-loading barrier. One means of increasing charge
density is to increase field strength by using a high dielectric
strength material opposite the barrier.
Now for a surprise. One way to achieve many of these objectives is
to make the back side an anode immersed in a water. The water acts
as the dielectric. The field strength across the two layer water
interphase can be well over 10^6 V/m.
The anodic diffusion barrier can be deposited and even maintained/
healed by anodization. The target for hydrogen tunneling then is OH-
molecules in the interphase, and any free electrons that might be
ionized off them and attached to the anodized barrier.
One problem with this approach is keeping the electrons from
tunneling across the backside barrier to the hydrogen instead of the
hydrogen tunneling through the back side barrier to the electrons.
The down side to electron tunneling through the backside barrier is
(1) deflation fusion is accomplished best by simultaneous deuteron
tunneling to an electron and (2) fusion on the front side of the
barrier will cause disruption of the lattice, destruction of the
barrier, and possible helium blockage.
Preventing the problems should be possible by energetically denying
them by driving front side electrolysis at a much higher voltage once
loading is complete.
Operating with a superimposed pulse, on both the front and back side
potentials, to trigger hydrogen barrier tunneling, may be efficient
because it gives the lattice time to diffuse replacement hydrogen,
backside gas a chance to dissipate, and the interphase to recover.
