The energy vesicle that is supposedly the basic unit of life. It is smaller than a cell, a liquid-filled membrane that pulsates continuously with orgone energy. The bion and orgone energy are both discoveries or inventions of Dr. Wilhelm reich, a 20th-century Austrian physician and psychiatrist. He believed that bions propagate like bacteria, and he produced photomicrographs showing aggregates of bions in the process of transforming into protozoa, small single-celled organisms. Conventional biologists have not been able to reproduce these experiments and believe that Reich’s material might have been contaminated with the organisms he claimed to see formed from bions.
