https://en.wikipedia.org/wiki/Zero-point_energy SNIP Physics currently lacks a full theoretical model for understanding zero-point energy, in particular the discrepancy between theorized and observed vacuum energy is a source of major contention.[4] Physicists Richard Feynman and John Wheeler calculated the zero-point radiation of the vacuum to be an order of magnitude greater than nuclear energy, with one teacup containing enough energy to boil all the world's oceans.[5] SNIP The term zero-point energy (ZPE) is a translation from the German Nullpunktsenergie.[9] The terms zero-point radiation or ground state energy are also sometimes used interchangeably. SNIP For decades most physicists assumed that there was some undiscovered fundamental principle that will remove the infinite zero-point energy and make it completely vanish. SNIP This possibility was ruled out in 1998 by the discovery of that the expansion of the universe is not slowing down but is in fact accelerating meaning empty space does indeed have some intrinsic energy. http://www.calphysics.org/zpe.html Quantum mechanics predicts the existence of what are usually called ''zero-point'' energies for the strong, the weak and the electromagnetic interactions, where ''zero-point'' refers to the energy of the system at temperature T=0, or the lowest quantized energy level of a quantum mechanical system. SNIP Zero-point energy is the energy that remains when all other energy is removed from a system. This behaviour is demonstrated by, for example, liquid helium. As the temperature is lowered to absolute zero, helium remains a liquid, rather than freezing to a solid, owing to the irremovable zero-point energy of its atomic motions.

[Is this why they have those high frequencies that JJ was talking about?] SNIP IS IT POSSIBLE TO TAP ZERO POINT ENERGY? As to whether zero-point energy may become a source of usable energy, this is considered extremely unlikely by most physicists, and none of the claimed devices are taken seriously by the mainstream science community. Nevertheless, SED interpretation of the Bohr orbit (above) does suggest a way whereby energy might be extracted. Based upon this a patent has been issued and experiments have been underway at the University of Colorado (U.S. Patent 7,379,286). http://www.huffingtonpost.com/peter-baksa/zero-point-field_b_913831.html SNIP In physics, there is something called the Casmir effect. In this experiment two conducting plates are brought parallel to each other with an electromagnetic field held between them. The cavity between the plates cannot sustain all frequency modes of the electromagnetic field, particularly wavelengths comparable to the plate separation. This creates a zero-point pressure on the outside of the plates, trying to push the plates together, much like how radiation pressure from the sun pushes a comet’s tail away from its nucleus. The resulting effect is called the Casmir force, and it increases in strength the closer the plates get, but vanishes once the plates make actual physical contact — or when the plates are so close together that zero-point wavelengths no longer see a perfectly conducting surface. [This seems to be what JJ was talking about] http://www.theplaidzebra.com/zero-point-energy-generators SNIP The concept of zero-point energy can be traced back over a century to 1891 when Nikola Tesla stated “Throughout space there is energy…If this energy is kinetic then it is a mere question of time when men will succeed in attaching their machinery to the wheel-work of nature…Many generations may pass, but in time our machinery will be driven by energy available at any point of the universe.” http://www.nuenergy.org/nikola-tesla-radiant-energy-system SNIP [1] Nikola Tesla, U.S. Patent #512,340, “COIL FOR ELECTRO MAGNETS,” he explains that a standard coil of 1000 turns with a potential of 100 volts across it will have a difference of .1 volt between turns. A similar bifilar coil will have a potential of 50 volts between turns. In that the stored energy is a function of the square of the voltages the energy in the bifilar will be 502/.12 = 2500/.01 = 250,000 times greater than the standard coil.
