From: H LV ➢ The type of "negative temperature" discussed in the article is not actually colder than absolute zero. It corresponds to something that has alot of energy so it cannot be called a heat sink.
Maybe not. Firstly, any and all mass contains “a lot of energy” in one appraisal, so that characteristic alone does not make a new kind of heat sink impossible. This goes beyond semantics in a way when we get down to specifics -- since the actual energy content of dense hydrogen, for instance, must be less than the natural species – assuming that it gave up energy in order to reach a dense state. OTOH a cooling or heat sink effect could serve to slowly “reinflate” the gas, which makes it of limited usefulness but definitely a thermal anomaly True – a dense state of hydrogen does not mean that the effective “coldness” is usable in a secondary (Boyle’s Law) way but all of this is wildly speculative. Obviously, the best if not only resolution is to find a way to produce and store dense hydrogen for later use in experiments. Mills claims to have done this, and possibly Norront as well - but most observers are not convinced. If Mills could really collect hydrinos, he would have demonstrated the hydrino-battery a lone time ago. In fact, the battery could be his best application of the effect (on paper).
