to view back 4 hours. Then I selected only P_Xs Low. Notice that the
excess power is oscillating between 4 watts and 8 watts, in a very
precise rhythm, with each wave appearing to have the same shape, and
with each wave lasting about an hour. I also see that the wave
appears to be tapering with the lows becoming higher and the heights
become lower. There also seems to be a correlation with T_Ambient, but why?
Re almost hourly fluctuations in T_Ambient -- the HVAC system
kicking in periodically, maybe?
If this is so, if it persists, then it could show that the
calorimetry is sensitive to ambient, as others have noted. This could
easily be tested. In some work, there is an outer environmental
chamber that is temperature-controlled. I'm seeing some work now
being done with isoperibolic or Seebeck calorimetry done inside of a
larger Seebeck. A temperature-controlled environment has often been
considered important, to remove that variable.
(Basically, a calibration at one ambient temperature is not accurate
at another.) Either all work must be done with constant ambient, or
calibrations must be done across the ambient temperature range. Cold
fusion calorimetry can be tricky, and I consider that the antifusion
coffin was only nailed shut by correlation with helium. We don't know
the ash with NiH reactions. If massive heat is ultimately confirmed,
that can overwhelm skepticism, but ... it has not been confirmed.
If the ash is deuterium, as Storms proposes, it's going to be
difficult, because deuterium is a normal and substantial contaminant.
But if the reaction is sustained for long enough, at high enough
levels, and especially with deuterium-depleted water (it's
available), a heat/deuterium correlation could be measured.
