    "abstract": "The name \u0027sorption heat engines\u0027 is proposed for simple negative entropy\ngenerators that are driven by thermal cycling and work on alternating\nadsorption and desorption. These generators are in general not explicitly\nrecognized as heat engines. Their mechanism is applicable to the fields of\nengineering, physics, chemistry, geology, and biology, in particular the origin\nof life. Four kinds of sorption heat engines are distinguished depending on the\noccurrence of changes in the adsorbent or adsorbate during the thermal cycle.",
