In psychology, Austrian-born American Wilhelm Reich’s theory of orgone energy is sometimes referred to as a radiating “biological energy”, a sort of theoretical spin-off of psychic energy. [2]
In 1973, Albert Lehninger, in his Bioenergetics, discussed biological energy in terms of the Gibbs free energy involved in the driving of biological processes and reactions. [1]
