Free Energy
The term free energy is used in several ways.
Free Energy in scientific physics
The term free energy is clearly defined in scientific physics and is used as Helmholtz free energy or Helmholtz potential. In physics it is a measurement for the useful work obtainable from a thermodynamic system, the amount of energy that can be utilized according to the second law of thermodynamics Helmholtz free energy.
Free Energy as a synonym for perpetual motion
In esoteric conspiracy theory circles, free energy is an allegedly inexhaustible type of energy which could replace fossil and renewable energy (solar power). According to supporters, its use was allegedly prevented by influential but otherwise unspecified groups. No objective evidence of such an energy is known.
Closely related to the esoteric hypothesis of free energy is the idea of a perpetual motion device. Such a device is not possible, as it would violate the thermodynamic laws of energy conservation in physics. Free energy supporters often use the term "overunity" to express that these claimed machines produced more usable energy than is fed into them (efficiency > 1). A number of frauds and profiteers offer commercial "free energy machines" or generators. In addition, fisherman's stories of an alleged suppression of the invention are often spread. Typical examples are Water-fuelled car, Cold Fusion or the Felix Würth AG.
As usual in other pseudosciences, there is no common nomenclature among the exponents of free energy. There are several alternative terms which are used as synonyms for free energy. Some of them are:
- Nonconventional energy
- NET (Nonconventional Energy-Technology) oder NCET (Non-Conventional Energy Technology)
- Zero-point energy (see also Claus Wilhelm Turtur)
- Orgone
- Space energy
- Tachyon energy
- Vacuum energy
Some of these terms have other meanings in science so that proponents of free energy can plead that free energy was known and researched in scientific physics, too.
The terms space energy, vacuum energy and zero-point energy, intend to suggest a relation to quantum mechanics, where systems in bound state at absolute zero still possess quantum mechanical zero-point energy. Zero-point energy in quantum mechanics has nothing to do with an inexhaustible energy source and the conservation of energy principles apply strictly in quantum mechanics.
The existence of a free energy field from which suitable machines can draw energy is not documented and there is no agreement how such a proof could be obtained. There are even no clues of what kind such a field should be. Authors postulating such a field implicitly assume that it would be of "psychic" or subtle energy nature and would not interact in a measurable way with the physical world – just with free energy machines. It is to assume that the term free energy or space energy is used as an ersatz hypothesis solely to avoid the term perpetual motion which is known as fiction, and would result in immediate rejection by the audience and potential customers. The concept of free energy corresponds to usual esoteric concepts. Furthermore, free energy is a serious term from physics, the concept of which is not known to or understood by many.
Business models and fraud
In the past, several attempts to market free energy investment methods mostly with fraudulent intent were promoted in German-speaking countries alone. An overview can be found here: Free-Energy-Business-models.
