Could be a *major* disadvantage to Pd, major reason Or maybe a major advantage, imagine a powerplant that consists of a whole lot of blocks of palladium that are cold-fused (oh no it got verbed already :-) to the point that thay are too hot to run and then moved to the heat exchanger to cool down, the next block of palladium moves into place etc etc The big advantage is NEGATIVE FEEDBACK, the worst thing that can happen is a puddle of palladium that stops fusing Paul -- Paul Campbell, Taniwha Systems Design, Oakland CA ..!mtxinu!taniwha!paul "'Give me your tired, your poor - I'll piss on them' that`s what the Statue of Bigotry sais.

Or the ring could be slowly rotating, to more closely approximate your suggestion. In either case, cyclic synchronization could be encouraged by commutating the Pd side of circuit... say, low voltage most of cycle, higher voltage as approach heat exchange area?? Or simply have a "waffle" pattern of heat resistant material in bottom of chamber, with a metal contact (higher melting point than Pd, of course) and a small amount of Pd in bottom of each depression. Ignore tendancy of each cell to affect its neighbors, and let the heat sink at bottom average-out the variations. (Also, build chamber to withstand pressure, and install a pressure relief valve set conservatively below that limit; pre-presurizing optional. But that's another topic!) (And don't forget your shielding! Would an inch of iron do with 2.5 Mev neutrons, or do you need a foot or two of concrete? Etc??) Frankly, this design may be far-fetched, what with how little I know; but a nice mental exercise. 'Take what you can use, leave the rest'. ---Phil (prs@oliven)
