- Dear Jed,
- Your public letter resorts to ad hominem attacks, even in its title:
- "Notorious Steven Jones". You further state that our efforts to understand
- the basis of the heat demonstrated to the world in Nagoya by Dr. Notoya
- are "unreasonable, unscientific, sloppy and uncalled for." You state that
- we should have talked to Notoya and taken data there. We did this, and
- have reported the voltage, current and power given to each cell. I trust
- the one correction to our report got through, that is, the joule heating
- to each cell was approx. the same, but the nickel-cathode cell had higher
- voltage (and total power) to account for loss due to water decomposition
- losses (the cell was open, letting H2 and O2 escape into the air). I agree
- with Tom Droege that xs heat claims based on open cells such as this are
- not reliable.
- So both David Buehler and I did speak to Dr. Notoya during the conference.
- We took measurements of the voltages and currents with her instruments, with
- her help, the alligator clips from the power supply were moved up the wires
- close to the control cell, and we then found that much of the power in this
- cell (36% - see earlier posting for details) was dissipated into the air.
- Then we did an experiment here to see whether the set up as demonstrated in
- Nagoya could result in about a 10 C difference in temperatures, based on
- differences in joule heating which we clearly expressed our concern to Notoya
- about in Nagoya. We found that the temp. difference could indeed be explained
- by differences in joule heating, with significant heat in the "control"
- dissipated into the air due to thin wires , while the "nuclear" cell had wires
- of approx. 1-mm diameter by my measurement there. Actually, the exact
- thickness of wires is less important than the power losses, which we measured
- as described in a previous posting.
- In science, we check each others' results. Openly. As I said in an
- earlier posting, no personal attack is intended on Dr. Notoya. Indeed, she
- obliged our request to move the alligator clips which allowed us to measure
- the (high) resistance of the thin wires entering the control cell. We spoke
- to her. We took measurements of a publicly demonstrated cell with the
- instruments displayed with it. We checked the result and conclude that the
- heat difference of the demonstration cells can be accounted for by differences
- in joule heating *in* the cells. I think this is consistent with standard
- scientific procedure.
- But Rothwell's ad hominem attacks are not.
-
- Sincerely,
- Steven E. Jones
