As far as I understand, most of the ideas concerning how fusion at low temperatures, and their relationship with eg. Pd is not because of chemical catalysis, but because it readily dissociates and dissolves hydrogen (and isotopes) into it's crystal structure.
This process brings the hydrogen atoms ( at ntp ) at least as close as hydrogen molecules at roughly 2000 atmospheres, and maybe much closer, if I punched in the correct numbers.
I believe it was (when cold fusion was, ahem, hot) speculated that the process of hydrogen solution/diffusion within the metallic matrix had somehow forced the hydrogen much closer together, while possibly creating local heating because of changes in the metallic structure at high hydrogen saturation, and that this was somehow both hot enough and close enough to create fusion.
- darkpuma 7y agoThat makes a lot more sense, thanks. But if the metallic lattice is retaining the pressure of bringing hydrogen nuclei that close together, wouldn't the whole thing tear itself apart? Is that the instability they're talking about when they say "But at high concentrations the team was unable to create stable samples." ?
- trhway 7y ago>at least as close as hydrogen molecules at roughly 2000 atmospheres, and maybe much closer, it is just a liquid hydrogen density. If any cold fusion is there i would bet that it would be some play due to huge electron cloud of Pd. Pressure/atom distance wise - the high pressure experiments using diamond anvil compress hydrogen up to 1M+ atm . That is still well below the Jupiter core though, and so naturally no fusion, yet one can make things interesting say by zapping that pressurized hydrogen with laser. Should get NIF style results with much less power or alternatively much better results with the NIF power.
