This Defense Intelligence Reference Document, DIA-08-1004-007, is dated 6 April 2010. The Defense Intelligence Agency's Defense Warning Office prepared it under the Advanced Aerospace Weapon System Applications Program. It reviews concepts for extracting energy from the quantum vacuum zero-point field for space power and propulsion. It covers the Casimir effect, QED and stochastic electrodynamics theory, and selected experiments. It notes that no practicable extraction technique has yet been demonstrated in the laboratory.
From the source:Release of 2026-09-18 Incident: 4/6/10, Las Vegas, Nevada. Released with redactions. This document is a Defense Intelligence Reference Document (DIRD), a technical reference format used by the Defense Intelligence Agency (DIA) to capture baseline knowledge on a specific topic for later analytic use. DIRDs are best understood as reference and synthesis products rather than as original research. It is one of 38 DIRDs produced under the Advanced Aerospace Weapon System Applications Program (AAWSAP) between 2009 and 2011. Because AAWSAP’s scope permitted a broad range of supporting topics, not every DIRD in the series directly concerns aerospace systems or future threat assessment. The following summary reflects the DIRD’s scope and framing at the time of writing and should not be read as implying current validation of the concepts discussed. This DIRD examines whether useful energy might be extracted from the quantum vacuum, the ground state with the lowest possible energy of quantum fields. This treatment considers applications for space power or “propellantless” propulsion by reviewing a range of concepts involving zero-point fluctuations, Casimir effects, squeezed vacuum states, Dirac-vacuum decay, and possible vacuum phase changes in quantum chromodynamics. The report argues that established physical models contain real vacuum-related phenomena, and that certain mechanisms can be modeled as energy-releasing phase changes under specific boundary conditions or intense external fields. However, it acknowledges that no practical method for continuous or useful energy extraction has been demonstrated experimentally and that standard quantum electrodynamics does not support continuous vacuum-energy conversion in the manner proposed. Frameworks based on the concepts described in the DIRD remain theoretically underdeveloped and experimentally unconfirmed at the time of writing.

Appendix: The QCD Bag Model
When considering the effective masses of quarks bound within hadrons, it is common to
think of the constituent masses of the quark and antiquark pair as their zero-point
energy (ZPE) when they are bound by the confining potential 25 (acting between a quark
and an antiquark) with an energy spectrum that corresponds to the masses of the
observed mesons. For charm, and heavier quarks, it appears that the total ZPE is not
much different from the masses of the lowest-lying meson states. This picture also
holds true for baryons. The quark-gluon model for hadrons is called "the bag model."
Even in an "empty" bag-that is, one containing no quarks-there will be nonzero fields
present because of quantum zero-point fluctuations (ZPF) . This gives rise to a zero
point (ZP) or Casimir energy inside the empty bag. The estimated total ZP/Casimir
energy of t he confined gluon field inside a spherical bag is E zP;:;: +0. 7/a (or +0. 7nc/a in
MKS units), where a is the radius of the bag in Gev-1 units. EzP is numerically the entire
story because the ZPE contribution of the confined fermion (quark) field is far smaller
than EzP (the leading approximation per degree of freedom is down by two orders of
magnitude) . A typical empty bag has an estimated radius a ;:;: 2.6 Gev-1 (0.5 fm), so EzP
~ 10- 1 GeV (or 10- 11 J), and this result rema ins approximately true if one uses a= 5.07
Gev-1 (1 fm) for a nucleon-sized bag. If the bag contains quarks, then this result does
not change because the quarks don't affect the ongoing quantum ZPF inside the bag
due to asymptotic freedom.
The inventor of the empty bag model (Ken Johnson) proposed that space is filled with
closely packed empty bags, and that the energy of space filled with contiguous bags is
simply the sum of the field energ ies contained within each bag. But this is not widely
accepted since the phenomenologically preferred model for the exterior "ordinary"
vacuum is given as follows.
QCD color confinement in hadrons is approximated by the phenomenologically
successful "bag model." In this model, the "ordinary" vacuum external to hadrons is a
perfect color magnetic (or chromomagnetic) conductor; that is, the chromomagnetic
permeability ~L is infinite, wh ile the chromomagnetic vacuum in the interior of the bag is
characterized by μ = 1. This implies that the color electric (Eqco) and magnetic (Sqco)
fields are confined to the interior of the bag, and that they satisfy the following
boundary conditions on its surface 5: n . Eqco Is = 0, n x Sqco Is = 0, where n is a unit
normal vector to 5. In other words, this model defines QCD vacua that coexist in two
phases: 1) an ordinary vacuum exterior to the bag, impenetrable to color; and 2) a
vacuum interior of the bag, in which the Yang-Mills fields that carry color (gluons)
propagate freely. Both phases are separated by the surface boundary of the bag upon
which the Yang-M ills and fermion (quark) field satisfy the aforementioned boundary
25 Quarks carry " color charge" as well as electric charge. Color charge is considered to be the "true" charge of
strong interactions. Gluons are the "photons" of strong interactions, and color is exchanged by eight bicolored
gluons, which are massless and have spin 1. Color interactions are assumed to be a copy of electromagnetic
interactions. Theoretical and phenomenolog ical studies found that the confining potentia l V(r) lies between a
Cou lomb and a harmonic oscillator potential: V (r) = - (4a s I 3r ) + kr, where r is the rad ial distance between
confined quarks, k is a constant parameter, and { is the color factor associated with as for the case of quark
antiquark pai r confinement in mesons. For the case of baryons (qqq), the color factor in V(r) is replaced by f .
