- Mike Jamison speculates on the source of the changes in gas absorption. We
- have looked at several cathodes (Chuck Sites did the looking - what say Chuck)
- and likely did not see many cracks. No doubt about it, large volumes of gas
- puff in and out. I still think it is some sort of surface effect where the
- gas is held near the surface and "sheets" off. I do *not* think it is
- a bubble effect. Try to put a 10 cc bubble in a 50 cc cell volume and have
- it stay for minutes.

- John Logajan asks "what is a surface grinder". You will find one in most
- machine shops. Imagine a grinding wheel and motor suspended above a two axis
- table - like a milling machine table. You can raise and lower the grinding
- wheel, and move the work under it. It is very easy on the right material to
- take very fine cuts. When you have the head of your hot rod refinished, it is
- likely done with a surface grinder. Certainly the bearing surfaces on you
- crankshaft are done with a similar machine. In any case, it is the next step
- down from normal machining. I guess lapping and then polishing are the next
- processes to use for a fine finish. Even so, a grinder and fine cuts will
- produce a mirror finish on steel.

- Thanks for all the pH advice. Next experiment will be done with 0.1 M LiOD
- and I will exchange part of it from time to time to maintain cell conductivity.
- I will have to learn to live with the resulting thermal transient.
-
- The present experiment looks null now that I have turned the current down to
- zero. But it again drifted in the direction of anomalous heat during the
- 1.4 megasecond run. About 70 mw. I now plan to just let it sit a few days
- and see what happens.
-
- Jed Rothwell has put up a long apology for the Notoya demonstration. As far
- as I am concerned, this is controversial work (cold fusion in general). So
- different rules apply. If anything is found wrong with an experiment, then
- you throw it out, and then demand much higher standards for the next work by
- the same experimenter. This holds for me too. I feell that I have used up
- a lot or credibility by my recent "positive" announcement. I will be even
- more careful in the future - even though these posts are not "publication".
- It is clear that there was something wrong with the Natoya demonstration.
- There was obviously heat going into lead dissipation that Dr. Notoya was
- proposing to go into the control cell. So I throw out the whole experiment,
- and require a much more thorough experiment from Dr. Notoya next time.
-
- John Logajan writes "Huh? Isn't the pH measurement redundant to your above
- stated observation? That is to say, average cell voltage indicates the
- state of the pH."
-
- I guess it does, John. But my goal is to have as many redundant measurements
- as possible. Two or three or four on everything. Then if they all agree, I
- can have some confidence in the result. If they don't agree, then I learn
- something new. That is even better.
