Eric, if you attend ICCF-18, I will answer this question during my talk.

This gets back to the earlier thread on the ion beam and glow
discharge experiments. I suspect that some of what they're seeing
in those experiments is real LENR, and that it is hasty to write it
off as hot fusion. You may recall an experiment that was recently
mentioned in which 350-1000 eV beams of deuterium nuclei were
accelerated towards 1 um deuterated titanium foils, and out of the
back came ~5 MeV particles (identity unknown). This is a little
like dropping pennies onto the ground on one floor of a building and
having cannonballs fall from the ceiling below. It's easy to lose
sight of the difference between 350 eV and 5 MeV, but it's large.
About the difference between a glow discharge/ion beam type
arrangement like Defkalion's and a purely thermally driven one like
the HotCat, it seems we can only speculate at this point. My
current line of thinking for the ion beam stuff -- there is
something in the electronic structure of the substrate that is at
work here, be it plasmons, or shielding, or cracks, my favorite,
sufficient deceleration in the fields of heavy lattice atoms to keep
the interacting nuclei close to one another for a prolonged period
of time sufficient to achieve tunneling and sharing of momentum with
the spectator lattice atom. (Note that this also opens the
possibility of a similar kind of interaction happening in a *gas*,
e.g., heavy noble gas atoms like xenon, with sufficiently strong
binding energies for the inner shell electrons.)
