In SED physics the Casimir forces is not thought of in terms of negative energy density. Anything other than positive energy is just confusing and not necessary. The zero point energy field is a frequency cubed spectrum of non propagating waves of all wavelengths all the way down to the Planck cutoff length. The closer you get to that cutoff, the more there are of them and the more energetic they become.
At the scale of meters, there are so few of these waves modes and they are of such low energy density that the ZPE is considered featureless. At the scale of atoms and subatomic particles it is considered a “seething sea”. All atoms and subatomic particles get “jittered” by impacting ZPE waves.
Because of the ZPE’s stochastic nature, everything remains in equilibrium. Casimir cavities are at the nano scale. At this scale the two plates restrict the longest ZPE wave modes. Note: that isn’t necessarily very many and they are of low energy density. But even just those few more modes outside the plates than inside is enough pressure to “push” the plates together.
That is the Casimir force and strictly speaking, that is NOT what allows for Dr Whites chips to create an endless electric current from the quantum vacuum. So what does? Remember I said that the ZPE “jitters” all atoms and subatomic particles? Okay.
Dr. White placed pillars at the mid plane of his Casimir cavities. What does this mean? It means that not only do the two plates restrict ZPE modes, the pillars restrict modes even further at the midplane.
In Dr Whites modified cavities: the walls/plates get jittered and the pillars at the midplane get jittered even less due to fewer ZPE modes at the midplane. Normally all things remain equal. In this case, the geometry causes non-equilibrium.
Because atoms in the walls are jittered more so than the atoms in the pillars, occasionally electrons from the walls preferentially tunnel to the pillars. Because the walls are electrically connected to each other and the pillars are electrically connected to each other but the walls and pillars are isolated from each other, an electric current is formed. That current runs outside the chip to power a key fob and returns to the cavity walls to complete the circuit.
It will allegedly never run out of current or electrons because of the simple fact that the quantum vacuum fluctuations never stop jittering the atoms in the walls.
It is talked about by Hal Puthoff that it is this jittering of atoms by the ZPE that sustains electrons in their orbits and the reason matter doesn’t instantaneously collapse on itself.
