Wow thanks for sharing. I didn’t know about this stuff. I guess refrigeration is much more interesting than I assumed! I definitely need to read up more about

  The Einstein refrigerator was a relatively more modern approach that had been more recently invented, and was quite a bit different than the established mechanical refrigeration. Even today these type are not as widely deployed as they could be, and I would expect Asimov was quite aware of their existence and unmet potential (that still lingers). As a futurist and believer in continuous improvement, you wouldn't want progress in any unperfected technology to ever stop. How else was science fiction going to become reality eventually in the future?

    moving-parts-free ammonia-absorption refrigerators (though not of the einstein-szilard type) are in wide use in industry and in motor homes, but subsequent improvements in the vapor-compression type made ammonia absorption less attractive for the most conspicuous applications, such as indoor home fridges (though i did encounter one unexpectedly in a hotel room in argentina last year) i am not entirely clear on the advantages of the einstein-szilard design over the earlier munters–von platen design, which as i understand it is the one commonly used today, and would be grateful for an explanation the story here is not one of stagnation
