We agree. I think his entire performance at the demos consists mostly
of misdirection.
Even if that were true, a 30 L vessel of water cannot remain at boiling
temperature for 4 hours, so we can be sure the claims are true. There is
a limit to how much misdirection can accomplish. There is a limit to how
much confusion the inept use of instruments can introduce. In this case,
you can throw out all of the instruments and still be certain of the
results.
Actually, by "misdirection" I had in mind some of his statements in his
blog, not his demonstrations. The demonstrations are straightforward and
easy to understand. Sloppy, with third-rate instrumentation, but no
misdirection. No skeptic has discovered any significant error, or any
reason to doubt the overall conclusion. Anyone can see many annoying
errors that detract from the results and make the results imprecise, but
that is not the same as significance. As long as the error cannot cause
the result to be wrong, it does not matter how big it is. In some
physics experiments, the error bars are huge but the result is still
irrefutable. In others experiments, the error bars are small, the
methods and instruments are impeccable -- the best available -- but
unfortunately the results are unconvincing.
Many skeptics do not seem to understand this distinction. They look at
the factors a college instructor would cite in grading an lab exercise:
neatness, correct use of instruments, documentation, exposition,
positioning of thermocouples, and other did-you-follow-the-textbook
criteria. They become so obsessed with these details they overlook the
actual test results, and the fundamental physics the test demonstrates.
