- To Frank Smith:
-
- I continue to be very confused about the gas situation. Remember, I have
- back filled with D2 and there is a catalyst. When I reverse the cell, I
- expect D2 and O2 to come off in the 2/1 ratio and proportional to the
- current. I also expect out-diffusion of D2 from the cathode. To my simple
- way of looking at things, the electrolytic 2/1 D2 and O2 simply re-combine
- in the catalyst. This leaves the out-diffused D2 as a net gain in gas
- volume.
-
- The idea of an empty cell at run start is to make absolutely sure that there
- is no chemistry going on. Sure there is a small thermal transient if the
- electrolyte fill is not at the same temperature as the inside of the
- calorimeter when it is added, but this can be computed and checked. Remember,
- I keep track of integral joules, so this is not hard. The calorimeter is
- not affected by putting things in it. (at least to first order - that is the
- whole idea of its design).
-
- To Mike Jamison:
-
- Note that I am not using a radiation detector, but a source. Presently a
- 2 micro-curie 60Co source. We are shining the source on the cell and noting
- the power level with the source on and off.
-
- When the time comes, and I think there is something to see, I will build a
- proportional chamber to look at what might be there. That is something I
- know how to do.
-
- To Kent Jones:
-
- Many people have weighed cathodes. Storms at Los Alamos has published an
- extensive study on this subject. But I know that sometimes the cathodes
- outgass very quickly, so a lot of gas can be lost on the weigh to the scale.
- Sometimes the cathods hold on to the gas. Very mysterious. One more thing
- to study if "anomalous heat" does not work out.
-
- The source is not inserted into the cell but put up against the wall of a
- dewar which contains the cell. Both have about the same thermal capacity -
- close estimate is 1 cc of H2O. If all the possible heat from handling some
- how made it into the dewar, then is would be at most a few joules. The
- measurements are typically hundreds of joules. But most of the heat would not
- so I would put an upper limit of this kind of error at 0.1 joule.
