That is the definition of zero degrees Kelvin according to my understanding. The question is how long does this state have to exist before the BEC action takes place? Has anyone calculated the length of time required? ***I've seen it referenced before that it needs to happen over a picosecond. The close proximity of the D's captured within a NAE would force collisions of this type to occur orders of magnitude more often than would be expected in a less dense plasma environment. ***That, in essence, is the YE Kim's BEC theory. The lower average temperature associated with LENR devices would lead to another benefit. Less relative velocity of the active D's would allow more time to be spent in close proximity at zero Kelvin since the stored potential energy would be much less than that found in high temperature plasma collisions. Less potential energy translates into less acceleration apart and more time to react. ***I suppose so. The real benefit of "lower average temperature associated with LENR devices" is that you don't need a hydrogen bomb in your water heater, once this technology becomes viable.
