Stewart, If mass can be converted to energy in packets of a fractional eV up to a few tens of eV, which seems to be a feature of many LENR theories - and the reaction is reversible so that energy can be converted into mass - the problem resolves to locating a nucleus which can vary in mass slightly without necessarily changing identity.
The "transfer medium" between mass and energy - is thought by some theorists
to be the quantum of spin - the magnon.
In the case of Ahern's EPRI work - the endothermic reaction ONLY occurred
when titanium was part of the nanopowder.
Since titanium has also been associated with gain in other experiments, it
would probably be the best lattice metal to concentrate on - in order to
show which parameters induce endotherm and which induce exotherm. Titanium
has two high spin isomers: 47 and 49 and a number of odd physical properties
that point to how one could engineer an experiment.

Thanks Jones, I have read so much stuff my head is spinning
like a toroid. I remember Celani last year talking about temperature
inversions during loading/heating phase of his wires for his demonstrations.
Jed has documents on his site discussing this from older studies, not sure
about recent.

I have liken it to a thunderstorm. When a low pressure
system rolls through it can pull a vacuum/create low pressure in the
surrounding gaseous atmosphere and cool things off overall but if you happen
to be close to lightning discharge within the area you might get very hot,
very fast... That lightning may be originating from a NAE since they have
detected positron emissions, neutrons, etc.. during storms

Actually there are four reports of LENR endothermic
reactions, including Arata and Ahern

Probably more examples were seen and written off as
calibration error, since endotherm is so unexpected.
Unless part of the "reaction" is endothermic
and cools its surroundings...
I do not think anyone has ever detected an
endothermic cold fusion reaction. You could detect that with a calorimeter
as easily as you can detect an exothermic reaction of the same magnitude.
