Molinology is the study of mills and other mechanical devices which use the energy of moving water or wind, or the strength of animal or human muscle to power machines for purposes such as hammering, grinding, pumping, sawing, pressing or fulling. More particularly, molinology aims to retain the knowledge of those traditional engines which have been rendered obsolete by modern technical and economic trends.
