- Many thanks to Bruc Dunn for an attempt at an overview of CNF experiments. I
- nominate Bruce as the keeper of the summary table, and hereby provide my input.
-
- Type 1 No recombiner, completely open.
-
- Mills runs this way. Plain water, very open to the air for his large cells.
- Ni Cathode, Pt anode, K2CO3 electrolyte. Sees heat.
-
- Ying. P&F type cell, open, but exposed to a source. Sees heat.
-
- Appleby. P&F type cell, not gas tight, Saw heat (Not Active?)
-
- Type 2, No recombiner, bubbler
-
- Huggins. P&F type cell, Saw heat, not active now, but Martha Schreiber of his
- group now works with McKubre.
-
- Type 3, Recombiner, bubbler
-
- Droege ran Mills experiments in this mode. No net heat seen.
-
- Type 4, Recombiner, orifice
-
- No experiments known to me in this category.
-
- Type 5, Recombiner, syringe or bellows
-
- Droege runs mostly this way. I have run with cell purges of Helium, Deuterium,
- Oxygen, and Argon. With the Deuterium purge, absorbed Deuterium is made up by
- more Deuterium from an auxilliary syringe. With the Oxygen purge, excess
- oxygen is taken off into an auxilliary syringe. The present run is with an
- Argon purge. The cell was filed and sealed up in the Argon bag. An early
- disaserous attempt was mad to fill with Helium. All that is left is a great
- picture of me in front of the apparatus with my cat and the Helium baloon I
- used as a source of helium. Wonderful American Flag on the balloon.
-
- Type 6. Closed and pressurized.
-
- McKubre and one of the Japanese runs this way. McKubre back loads with up to
- 10,000 psi of D2 gas. There is no vent. Evolved gas just builds up the
- pressure. But now I guess (after the accident) that the blow out plugs are set
- for lower pressure. He said the last runs were made at 50 psi, I remember.
-
- The big mystery is how P&F run. To my knowledge they have never told us. The
- early paper said "sealed with parafilm". What the heck is parafilm? But if
- they seal the cells, they have to vent the gas. My guess it that they are
- Type 2, but perhaps someone can fill in. Remember that even Hawkins was never
- in the back room, so we have to get the answer from P or F.
-
- The only first class experiment that I know of (McKubre) runs with a 100%
- D2 fill. I guess 10,000 psi is a lot of kPa. McKubre says that this high
- pressure completly prevents the formation of O2 bubbles. Perhaps someone
- can explain this. Where does the O go if it does not make bubbles? But he
- has also claimed excess heat at the much lower 50 psi.
-
- How about it Bruce, do you want to be keeper of the matrix? If so I will start
- sending everything I can find. At present I am keeping what I know in my head
- and trying to do the same job as you in trying to find a common thread in the
- successful experiments.
