>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.
