Reviewing present-day means of producing cold, one is struck by the fact that refrigerators, that is, machines for producing cold, operate over only the temperature range between the ambient or room temperature and -80°C. A second point is that in most refrigerators the cold is produced by evaporating a liquid. It is amazing that of the many possibilities offered by Nature, only one is actually utilized, In this article, we give a survey of another method, which may provide a welcome extension of refrigerating technique.
