*        I want to ask you about your thougths about the variation in proton
mass.  Should the variation be measurable with high sensitivity mass
spectrometers?

Yes and no. This is not unlike the problem of mass-4 similarity between D2
and He but more demanding. There could be repeatable statistical variation
over a large population within measurement error of the very top level
specialty spectrometer, running for substantial time periods. But in an
average lab – no way. 

Given Rossi’s claims, it might even be possible to actually weight the
difference on a sensitive scale if the hydrogen sample was say 10 grams of
H2 from a blue box which had given up say a gigawatt of heat over 6 months.
There are nanogram scales using piezoelectric effects which could be
modified.

*       I suppose that even a 1% variation would be more than enough to
supply all of the nuclear energy that we are seeing since the energy content
of the standard mass is so great.

Not that large. The usable mass variation for protons appears to be about 70
ppm (part per million). If the distribution is a bell curve, then perhaps
one third of the population can be further depleted. In short, the average
gain possible can be calculated to be about 5,000-10,000 times more than
chemical but about 1,000-2,000 times less than nuclear fusion.


*       Also, are you aware of any super accurate mass measurements that
have shown variation in this factor?  

I have a collection of published measurements of proton mass (going back to
the cold war era) where there were substantial reported variations,
especially as seen in Russia. Different instrumentation. Nowadays, everyone
automatically seems to use the same value.
