Steorn Power Source: Zero-Point Energy?

Wednesday, August 8, 2007

One of the most likely power sources for the free-energy claims of Steorn is that of the zero-point field or (vacuum energy). An already established scientific phenomena. The zero-point energy can be described as the following excerpt from Wikipedia:

In physics, the zero-point energy is the lowest possible energy that a quantum mechanical physical system may possess and is the energy of the ground state of the system.

The concept of zero-point energy was proposed by Albert Einstein and Otto Stern in 1913, which they called "zero-point energy" (German: Nullpunktsenergie). All quantum mechanical systems have a zero point energy.

The term arises commonly in reference to the ground state of the quantum harmonic oscillator and its null oscillations. In quantum field theory, it is a synonym for the vacuum energy, an amount of energy associated with the vacuum of empty space.

In cosmology, the vacuum energy is taken to be the origin of the cosmological constant. Experimentally, the zero-point energy of the vacuum leads directly to the Casimir effect, and is directly observable in nanoscale devices.

Because zero point energy is the lowest possible energy a system can have, this energy cannot be removed from the system. A related term is zero-point field, which is the lowest energy state of a field, i.e. its ground state, which is non zero.

Despite the definition, the concept of zero-point energy, and the hint of a possibility of extracting "free energy" from the vacuum, has attracted the attention of amateur inventors. Numerous perpetual motion and other pseudoscientific devices, often called free energy devices, exploiting the idea, have been proposed. As a result of this activity, and its intriguing theoretical explanation, it has taken on a life of its own in popular culture, appearing in science fiction books, games and movies.
