- The issue in any experimental investigation is not how big an effect
- you claim, but whether the effect is real and reproducible. In
- particular, I always look for the control of systematic errors and
- the significance of the signal.
-
- One of the strengths of this latest work by Jones is that he has a
- number of detectors and a setup where he can monitor coincident
- events with particular emphasis on bursts. His signal to noise in
- that experiment looked very good; there were no coincident events
- except for very rare cases that consisted of a burst of tens to
- hundreds of neutrons. A burst or nothing. The "accidental" rate
- is thus zip, although the energy produced is also zip because of
- the low rate of bursts -- one every day or so I recall.
-
- Thus I think it is more likely that Jones is close to establishing
- a *nuclear* effect that is at variance with simple predictions than
- that P&F(&H) have established a nuclear fusion effect.
-
- I think it is, unfortunately, also true that P&F have not yet established
- heat effects in a controlled and reproducible fashion ... at least in
- the sense of a published paper or patent that describes a device that
- anyone skilled in the art could construct and obtain a well-defined
- effect in a reliable and consistent fasion. (They may have done so to
- their own satisfaction in private, but that is not the same thing.)
