In human thermodynamics, informed energy is a hypothetical type of energy that is supposed to account for free will, the will of animate atomic structures, such as cells, and the beginning of life. The term "informed energy" was conceived in 2000 by Russian-born American physicist Valery Chalidze, in his book Entropy Demystified, where he argues that what separates supposed non-life atomic structures, such as crystals and polymers, from life-like atomic structures, such as a cell, is the "ability of a group of particles to separate itself from entropy waste". Chalidze defines the term as follows:
“Ordering work requires energy channeled for performing certain tasks according to certain rules … in other words, it calls for informed energy, and this is, I dare say, the best description of manifested human will.”
