Axil, please keep thinking, posting, and discussing. It is what this vo-collective is for! They are good explorations.
I believe the reason for the Rossi's flattened reactor is simply to better couple the heat out of the powder. The inside may be filled with posts to further improve the coupling. The trouble is that this design is terrible as a pressure vessel and will be terrible for permanently sealing in H2. He even had trouble with his flat water seals. Cylindrical symmetry is SO much better for high pressure seals! I suspect that the cylindrical pile of powder in the previous design is adequately thermally averaged by the high pressure H2 which has excellent thermal capacity. I would have made different choices for coupling the heat in/out and remained with cylindrical symmetry for the pressure vessel.

When the quench was switched off, the condensate having a superconductor like nature would quickly reform and proton pair fusion would restart.* I agree with you entirely. I believe the quench is an AC magnetic field so as not to permanently magnetize anything - which could permanently quench the reaction. If this is the case, it would also say something about the mechanism of the reaction. It could also be responsible for failures of some experiments - having too much residual magnetic field in the fuel in their experiment. Could the Earth's magnetic field be too much? Would Rossi's choice of stainless have protected the fuel from the Earth's magnetic field? I have experimented with sonoluminescence before and I find LeClair's account fascinating. Seems like I recall the diamond formation to have come when the fluid being used was acetone, not water. In such case, there is no need to invoke transmutation to get the carbon for the diamonds.
