- Prospects for harnessing the cosmic quantum vacuum energy for practical
- interstellar propulsion, time travel and space-like communication.
-
- "It would be just as presumptuous to deny the feasibility of useful
- application as it would be irresponsible to guarantee such application."
- attributed to R. Podolny by Hal Puthoff.
-
- Hal Puthoff's work on extracting useful energy from the quantum vacuum
- using the Casimir force looks very interesting.
- Puthoff writes:
- ".. the Casimir force, ... closely-spaced metal plates being pushed
- together ... is due to radiation pressure from the background
- electromagnetic zero-point energy which has become unbalanced ..(by).. the
- plates. This attractive force is proportional to 1/D4... and becomes quite
- strong at (D) ... on the order of 1000 Angstroms ...
-
- An alternative candidate .. to obtaining energy from vacuum fluctuations
- might lie in ... cold, dense, ... plasma in which charge condensation
- occurs on the basis of a Casimir pinch effect ..."
-
- My "precognitive" intuition assures me that eventually we earthlings will
- build star ships powered by zero point energy. We will be able to amplify
- traversable time-machine wormholes out of the quantum gravity foam for our
- ships to fly through. We will be able to communicate in "subspace" faster-
- than-light on the quantum connection in a globally causally consistent
- forever expanding universe. Indeed, if some UFO reports do prove to be real
- in the near future, some of them are sure to be such ships from our future
- manned by our descendants.

- "".. with the theory of the inflationary universe ... the entire universe
- was created as a 'false vacuum', ... the decay of that particular vacuum
- to an ordinary quantum vacuum produced all the mass in the universe and
- started the Big Bang."
- from The Timetables of Science quoted by Puthoff in Speculations in Science
- and Technology 13, 4, p.247, 1990 - more excerpts follow:
-
- ".. an expression for the spectral energy density that characterizes the
- vacuum electromagnetic zero-point energy
-
- p(f)df = f^3df/2pi^2 [joules/m3, hbar = 1 = c] (1)
-
- with a high frequency cut-off at Planck scale 10^-33 cm)
-
- S[p(f)df] = 10^94 grams/cm^3
-
- This f^3 zero point energy (ZPF) density is Lorentz invariant.
-
- "Whereas motion through all other radiation fields ... can be detected by
- Doppler-shift ... the ZPF spectrum with its cubic frequency dependence iis
- unique in that detailed cancellation of Doppler shifts with velocity
- changes leaves the spectrum unchanged ... It is also the case, unique to
- the ZPF cubic frequency .. that Doppler shifts due to ... cosmological
- expansion, gravitation ... also do not alter the spectrum. This stands in
- contrast to, for example, the 3K blackbody microwave background left over
- from the Big Bang which cools with cosmological expansion.
-
- Yet another feature .... is the complete lack of a drag force (the
- Einstein-Hopf drag ... p(f) - (f/3)dp/df -> 0 if p(f) = f^3.
-
- On the other hand, accelerated motion through the vacuum can in principle
- reveal the presence of the ZPF energy density directly .... One factor
- yields a thermal (Planck) spectrum of temperature
-
- T = (hbar)a/2pick, where a is acceleration, k is Boltzmann's constant..
- This is known as the Davies-Unruh effect.
-
- "Yet another factor which shows up in the ZPF spectrum of an accelerated
- observer is found, via the equivalence principle, to reveal a deep
- connection between zero point energy and gravity along lines orginally
- proposed by Sakharov .... "
-
- "... the Casimir effect ... With parallel, non-charged conducting plates
- set a distance D apart, only those (electromagnetic) modes which satisfy
- the plate boundary conditions (vanishing tangential electric field) are
- permitted to exist. In the interior space this constrains the modes to a
- discrete set of wavelengths for which an integer number of half-wavelengths
- just spans the distance D ,,, no mode for which a half-wavelength is
- greater than D can fit ... all longer-wavelength modes are excluded ... The
- constraints for modes exterior to the plates .. are much less restrictive
- due to the larger spaces .. Therefore, the number of viable modes exterior
- is greater than that interior ... the radiation pressure inward
- overbalances that outward ... the plates are pushed together with a force
- that varies as 1/D^4 ... the plates will move toward each other. The
- conservation of energy dictates that in this process potential energy is
- converted to ... kinetic energy .. the conversion of vacuum energy into
- heat .... What takes getting used to ... is that the vacuum state does not
- have a fixed enegy value, but changes with boundary conditions. .. vacuum-
- plus-plates-far-apart is a higher energy state than vacuum-plus-plates-
- close-together ... in Forward's ... design ... the two plates are charged
- with the same sign ... At sufficiently small spacings the Coulomb repulsion
- .. 1/D^2 ,, can always be overcome by the stronger 1/D^4 attractive Casimir
- force. ... This confines the charge distribution to smaller and smaller
- volume and results in an increased electric field ... the zero-point energy
- (Casimir energy) is transformed into stored Coulomb energy, which can then
- be extracted ... the (Forward) generator is a one-shot device. To recycle
- the generator one must put as much energy into the device to return the
- plates to their original separated positions .... not even 'break0even'
- operation can be achieved ... however, if one could arrange to have an
- inexhaustible supply of such devices, and if it took less energy to make
- each device than was obtained from the Casimir-collapse process, and if the
- devices were discarded after use rather than recycled ... a possible
- candidate ... would be the generation of a cold, dense, non-neutral
- (charged) plasma in which charge condensation takes place ... on the basis
- of a Casimir pinch effect ..."
-
- Indeed, if cold fusion cells really do produces excess energy the mechanism
- will not be thermonuclear fusion but, rather, this kind of Casimir pinch
- effect. It may also be possible to create a "unitary" quantum connection
- communication device by focusing the "transmitter" part of pair correlated
- light into an active beam splitter in which Casimir pinch electric fields
- are non-linearly converted to "cloned" transmitter photons. It would not
- be necessary to clone photons for every possible orientation of the
- transmitter amplifier so that the superposition principle need not be
- violated as it was in Nick Herbert's FLASH gedankenexperiment. This
- proposal is admittedly "half-baked" - a telepatype from the future?
