The error bars are big and I gather some theorists agree they are
too big to establish the mechanism. But the data does prove the
correlation. Especially Miles' dataset.
Whatever those error bars are, the ratio of heat to helium is
pretty close to plasma fusion, if not bang on. I mean, it is not
off by a factor of a million or a billion, the way neutrons appear
to be.

Agreed. However, a difference of 20% or more, if way outside the
error bars, could eliminate some theories and support others. I just
don't think the data is good enough yet, and may never be unless much
larger helium volumes are created, or some means is found to skew the
branching ratios toward producing more tritium. I think there is no
doubt the main "ash" is He4, it is just the precise ratio of MeV to
4He that I think is not nailed down precisely enough to ascertain
that the excess energy from D + D -> 4He is derived solely from and
corresponds perfectly to 23.9 MeV per fusion. If I recall, most of
the He data indicates *less* energy than that. Miles and Hollins
found a "correlation" to excess heat. They write:
"For this reaction 1 W corresponds to a rate of 2.62 • 1011 4He/s.
The highest excess power observed at 528 mA (0.46 W, 10/21/90-B,
Table 1) would therefore produce 5.4 • 10^14 atoms of 4He in the time
period required to fill the 500 ml collection flask with D2 and O2
gases (4440 s). About 10^14 atoms of 4He were detected, which is
within experimental error of the theoretical amount."

A much more thorough review is by Miles:
http://www.lenr-canr.org/acrobat/MilesMcorrelatioa.pdf
Miles' *best* result was 1.9 x 10^ 11 He atoms per s^-1 W^-1, vs the
theoretical value of 2.6 He atoms per s^-1 W^-1, which shows a
deficit of 27%.
I bring this up mainly because the deflation fusion model predicts a
deficit from the 23.9 MeV per fusion, at least as correlated to
immediate excess heat generation. It also predicts the (slim)
possibility of exceeding this value for very long running experiments
especially ones which occupy a large enough volume to trap hyperons
that may result. See:
