This is the companion piece to the high-voltage discharge work, and it is the one that states the force result directly. Evgeny Podkletnov, working in Moscow, with theory from Giovanni Modanese in Bolzano, describes a machine built around a two-layer ceramic disc: a superconducting YBa2Cu3O7-y layer grown on a normal-conducting rare-earth layer, eighty to a hundred and twenty millimetres across, cooled to between forty and eighty kelvin with a magnetic field frozen into it. A twenty-capacitor Marx generator delivers up to two million volts across a vacuum chamber, and the peak current through the disc reaches ten thousand amperes for between ten and a hundred microseconds. At each discharge something leaves the emitter along the axis. It deflects pendulum bobs of metal, glass, ceramic, wood, rubber and plastic by the same amount for the same mass, at six metres and at a hundred and fifty, through brick and steel. The authors call it a gravity impulse and offer a vacuum-fluctuation mechanism for it.
Pourquoi cela compte iciChapter 11 follows the superconductor-and-gravity thread, and this preprint is where the claim is at its most specific: a named apparatus, a fabrication recipe written out stage by stage, two tables of deflection against voltage, and a stated force law. It is also the paper the chapter's discharge sources depend on, because the companion 2003 journal article describes the same machine and this one carries the pendulum numbers.
Ce qu'il affirme
01The emitter is a bi-layered ceramic disc, eighty to a hundred and twenty millimetres across and seven to fifteen millimetres thick: a superconducting YBa2Cu3O7-y layer containing small amounts of cerium and silver, grown on a normal-conducting layer of the same structure with a rare earth substituted for part of the yttrium. Both layers are made by solid state reaction under low oxygen pressure, melt texture growth, and then seeded oxygen-controlled melt texture growth with samarium single-crystal seeds, and the fabrication is written out stage by stage so another laboratory can follow it.Section 2.2, Superconducting emitter, fabrication methods, Stages 1 to 4
What to watch02The discharge is driven by an Arkadjev-Marx generator of twenty capacitors of twenty-five nanofarads each, charged to fifty to a hundred kilovolts and then switched into series to deliver an impulse of up to two million volts. At maximum voltage the peak current is of the order of ten thousand amperes and the whole discharge lasts between ten and a hundred microseconds, implying a charge on the emitter of up to a tenth of a coulomb and an effective capacitance three orders of magnitude above what a normal conductor of that size would carry.Section 2.1, General description of the installation; Section 4, Discussion, point (a)
What to watch03The measured deflection rises smoothly with discharge voltage. For one emitter and an eighteen and a half gram rubber bob on an eight hundred millimetre string, five hundred kilovolts gives a deflection of 56.5 millimetres and an estimated energy of 3.6 times ten to the minus four joules, rising to 142.0 millimetres and 23.1 times ten to the minus four joules at two million volts, each figure the average of twelve discharges with a standard deviation between five and seven percent.Section 3, Results, Table 1 (Emitter N. 2) and Table 2 (Emitter N. 1)
What to watch04The impulse is reported to act on the mass of a test object and not on what it is made of. Spheres of metal, glass, ceramics, wood, rubber and plastic between ten and fifty grams deflect equally at constant voltage, and readings taken at three to six metres and at a hundred and fifty metres agree within the experimental error, with a brick wall of three tenths of a metre and a twenty-five millimetre steel plate in the near path and a further eight tenths of a metre of brick before the far one. A condenser microphone rotated through ninety degrees records an angular response consistent with a vector force acting on its diaphragm, and no signal outside the beam.Section 3, Results, on pendulum materials, on the 3 to 6 metre and 150 metre measurements, and on the microphone response
What to watch05The authors' proposed mechanism is an anomalous interaction between a particular class of gravitational vacuum fluctuations and the macroscopic wave function of the superconductor, switched on locally when the product of the Cooper-pair density and its second derivative is large enough and the second derivative is positive, which is a condition they argue is met where intense transport current and magnetic flux penetration coincide.Section 4.1, A possible theoretical explanation; Section 5, Conclusions
What to watch06What would settle it is stated by the authors themselves: they describe the results as preliminary, note that an improved version of the experiment was being planned, and name the emitter variables that change the size of the impulse, which are the thickness of the superconducting layer, the trapped magnetic field and the crystal structure produced by seeded growth. Those are the parameters an independent build would have to match.Section 1, Introduction, on the preliminary status; Section 3, Results, on emitters N. 1 and N. 2 and on the trapped field
