This Defense Intelligence Reference Document from the Defense Intelligence Agency, dated 6 April 2010, is one in a series of FY 2009 advanced technology reports produced under the Advanced Aerospace Weapon System Applications (AAWSA) program. It reviews the physics of zero-point field energy in the quantum vacuum and proposed schemes for extracting it, including the Casimir effect, Forward's vacuum-fluctuation battery, and resonant dielectric spheres. It notes that no practicable extraction technique has been demonstrated in the laboratory.

The strength of the SED model is that it is heuristically appealing, with transparent derivations, and it is applicable to linear systems. SED calculations have also been shown to be in one-to-one correspondence with the expectation values of the Heisenberg quantum equations of motion for linear systems. Both SED and QED will play a role in the discussions to follow. IV. Review of Selected Experiments In what follows, is an outline each of the proposed experimental concepts that were selected for theoretical and laboratory investigation. A subset of our proposed concepts has undergone preliminary evaluation by Lockheed-Martin review panels involving both internal R&D personnel and outside experts on theory and experimentation (V. Teofila, private communication, 2005). VOLTAGE FLUCTUATIONS IN COILS INDUCED BY ZPF AT HIGH FREQUENCY In a series of experiments, Koch et al. (Reference 18-20) measured voltage fluctuations in resistive wire circuits that are induced by the ZPF. The Koch et al. result is striking corroboration of the reality of the ZPF and proves that the ZPF can do real work (cause measurable currents). Although the Koch et al. experiment detected minuscule amounts of ZPF energy, it shows the principle of ZPF energy circuitry to detect vacuum fluctuations and opens the door to consideration of means to extract useful amounts of energy. The secondary consequences on other phenomena, if energy can be successfully extracted, have not yet been investigated. Blanco et al. (Reference 21) have proposed a method for enhancing the ZPF-induced voltage fluctuations in circuits. Theoretically treating a coil of wire as an antenna, they argue that the antenna-like radiation resistance of the coil should be included in the total resistance of the circuit, and suggest that this total resistance should be used in the theoretical computation of ZPF-induced voltage fluctuations. Because of the strong dependence of the radiation resistance on the number of coil turns (quadratic scaling), coil radius (quartic scaling), and frequency (quartic scaling), any enhanced ZPF-induced voltage fluctuations should be measurable in the laboratory at readily accessible frequencies (100 MHz compared to the 100 GHz range necessary in the Koch et al. experiments). In the theory of Blanco et al., random voltage fluctuations are conveniently described by their frequency spectrum. That is, given a sufficient time interval of measured voltages, the measurements are Fourier transformed to the frequency domain to determine how the voltage fluctuations are distributed (for example, quantity of low- frequency, long duration fluctuations relative to high-frequency, short-duration 7 UNCLASSIFIED/ ,'l"9" 91"l"!e!*le 1!191!! 9111!Y
