- David Buehler, Prof. Lee Hansen and I visited Dr. Takahashi's laboratory
- on October 27, 1992. I wish to report a few of our observations there,
- which we also reported to Dr. Takahashi.
- The electrolytic cells in which xs heat was reported were open, with
- D2 and O2 gases escaping into the air (a red flag as Droege emphasizes).
- In fact, we saw dried salts on the tops of the plastic cells showing that
- electrolyte had somehow reached the outside of the cells. Chromel thermo-
- couples were used to measure temperature, placed in the electrolyte with
- teflon wrapped around the thermocouples -- but this is not a sufficient
- barrier to the electrolyte. Chemical and even electrolytic processes could
- thus occur on the thermocouples, leading to small voltage variations which
- would be interpreted as temperature changes. We asked about the calibration
- for the heat measurements. Dr. Takahashi replied that since the electrolytic
- cell had vigorous bubbling whereas there would be no bubbles with a resistance
- heater, there was *no* calibration. This seems unbelievable to me, and there
- may have been a language problem, but this is what we recall and is recorded
- in my logbook.
- Dr. Takahashi is experienced in nuclear measurements, not in calorimetry. His
- measurements of neutrons and charged particles appear to be quite good. Of
- course, one must add that the level of these nuclear emissions is a trillion-
- fold less than required to produce one watt of xs power. I see *no*
- correlation. He reports a type of anti-correlation, with neutron emissions
- decreasing as xs heat rises. Furthermore, there is no quantitative
- correlation, with neutrons too few by about a trillion-fold to account for
- the xs heat, according to his measurements.
- Prof. Lee Hansen of BYU is an experienced calorimetrist. He has written a
- brief treatise on what is needed for careful, definitive heat measurements.
- This is being forwarded to Dr. Takahashi, Dr. Notoya -- others may request
- the paper by a note to me. It may be published in the proceedings of the
- cold fusion meeting at Nagoya, hopefully.
- Best Regards,
- Steven E. Jones
