Frederick Alzofon was a specialist engineer at Boeing Aerospace when he presented this paper at the 1981 Joint Propulsion Conference, and what makes it unusual is how concrete it is. He models the gravitational field not as the geometry of spacetime but as a cloud of virtual processes around matter whose mean energy sets the strength of the force — a picture close enough to the kinetic theory of gases that you can sensibly ask what it would mean to cool it. His answer is dynamic nuclear orientation, an established laboratory technique: line up the nuclear magnetic moments in a specimen of aluminium seeded with iron inclusions, using a steady magnetic field and a pulsed oscillating one, and the virtual cloud loses its order and its energy with it. He gives the field strength, the pulse length, the duty cycle and the metallurgy, sketches the vehicle it would fly, and says plainly that the experiment should be performed.

Why it matters hereChapter 11 needs proposals that name their own first test, and this is one — materials, field strength, pulse timing and an expected number, published at a propulsion conference by a working aerospace engineer. Mark Sokol's programme is building on it now, and Tajmar's group has since re-examined the weight-reduction experiment with NMR spectroscopy, which is exactly the exchange the chapter exists to track.

What it claims

  1. 01Alzofon proposes a semi-empirical model of the processes leading to the gravitational field, based on accepted features of subatomic processes — the annihilation and creation of matter-energy shared by all of them — formulated in semi-classical terms so that it can be treated by analogy with the classical theory of gases.Abstract; Part I, Section 1.1

  2. 02By using the analogue of processes occurring in cryogenics it is possible to reduce the mean energy of the random virtual processes asserted to be responsible for the gravitational field, and therefore to reduce the gravitational force; the same model suggests a method of increasing it.Abstract; Part I, Section 1.0

    Designed, not yet built
  3. 03The practical route is dynamic nuclear orientation applied to a specimen of aluminium with iron inclusions: a fixed magnetic field of about 660 oersted with a pulsed oscillating field, pulses lasting two microseconds on a duty cycle of two to six milliseconds. Because the virtual states are far shorter-lived than nuclear thermal relaxation times, the effect should be obtainable at temperatures much higher than conventional nuclear orientation requires.Part I, Sections 2.1–2.4, Experiment Parameters and Comments

  4. 04On Alzofon's own estimate, with a ratio of about one iron nucleus to ten aluminium nuclei, of the order of one joule of gravitational energy could be removed per duty cycle — against the 6.3 × 10⁸ joules of gravitational energy per gram of mass at the Earth's surface.Part I, Section 2.4

    Designed, not yet built
  5. 05The generated field is expected to reduce the vehicle's inertial mass to some extent as well, so that very high velocities and accelerations become possible and no large take-off acceleration is required.Part I, Section 2.5, Vehicle Design

    Designed, not yet built
  6. 06The unified field theory in Part II exhibits inertial mass, gravitational mass and the electromagnetic field as different states of the same field, recovers the inverse-square law of gravitational attraction for static mass distributions with no permanent charges or currents, and eliminates the infinite zero-point energy of the quantum mechanics of fields, giving it a new interpretation.Abstract; Part II
