If the Calvet paper below is accurate, among other 'miracles' energy can be cohered from ambient conditions by the lower temperature of a QM "heat sink"... Ref:
http://www.journaloftheoretics.com/Articles/3-1/calvet-final.htm The authors provides evidence that Casimir force can be considered as a 1-dimensional force vector that is scattered in a 5-dimensional space. To understand that - one needs to think about the main facts as presented in the abstract: Abstract: Conventional forces like gravitation and electromagnetism vary with the square of the distance. This is because the corresponding force is scattered into 3 dimensions due to the distribution of virtual gravitons or photons of the corresponding field in a 3D-space. In an analogous way, the Casimir force, that varies with the 4th power of the distance, ought to arise from bosons distributed in a hyperspace with 5 real physical dimensions. This leads to the prediction of a whole new world of “quantum temperatures” below zero Kelvin, and to a model that surprisingly agrees with cosmology and recent findings of the zero-point-field (ZPF). “Virtual” field particles (e.g. bosons of the ZPF) are probably nothing else than hyperspace particles that cross our 3-D universe from time to time, thus seeming “virtual” to us. This paper details how our universe can be considered as a 3-D space “floating” on an immense 5-D space - the hyperspace - in analogy to a sheet of ice floating in a deep sea.
