A comparison between the YBCO discharge experiments by E. Podkletnov and C. Poher, and their theoretical interpretations

Abstract

Experimental results recently published by C. Poher provide independent evidence for the anomalous radiation emitted from YBCO electrodes under short, intense current pulses previously reported by E. Podkletnov. The generation conditions are somewhat different: lower applied voltage, longer duration of the pulses, absence of a discharge chamber. The microstructure of the emitter is also different in the two cases. While Podkletnov's radiation beam is collimated, Poher's beam is more or less diverging, depending on the emitter type. In coincidence with the radiation emission Poher measures a strong recoil of the emitter, with maximum momentum of the order of 1 kgm/s. We compare and discuss several details of the experiments and give a brief outline of the proposed theoretical explanations. We also report numerical simulations of the maximum electromagnetic recoil force on a Josephson junction, as a benchmark for a possible alternative explanation of the recoil.

Anomalous Effects from Dipole-Environment Quantum Entanglement

“…Even so, although a lot of measurements of inertia in capacitors operating in high voltage have supported the existence of their apparent weight reduction [5,[9][10][11], there has still been a reasonable controversy, mainly due to the weakness of the force generated on the devices. However, the studies have been more and more conclusive in the last years about the existence of the phenomenon due to an increasingly relevant research work by means of a lot of recent publications [7,12,13,22]. Moreover our early works based on huge automatic collected data by using very advanced accelerometers [19][20][21] also corroborate the existence of Biefeld-Brown effect.…”

“…We have studied a lot of very interesting and intriguing experimental results reported in several works [1][2][3][4][5][6][7][8][9][10][11][12] concerning to anomalous effects mainly associated with the operation of traditional high energy capacitor devices. The anomaly occurs in inertia measurements and it presents a more intense magnitude of the raised force in experiments involving asymmetric capacitor devices [13][14][15][16] when they are subjected to high voltage.…”

Theoretical Study of Anomalous Forces Externally Induced by Superconductors

“…Other possibilities tried were to explain the effect by means of generalized Maxwell equations that simultaneously treated weak gravitational and electromagnetic fields [29,30] by considering the weak field approximation for Einstein equations [31,32]. In a sequence of works in the field, G. Modanese also presented studies concerning to possible alternative explanations to the effect [33][34][35][36][37].…”

Theoretical Limits on the Efficiency of a Quantum Vacuum Thruster

“…The exchange is brought about by strong, still little-known, gravitational vacuum fluctuations. At least two experiments [14,15,16] have demonstrated this effect, which is much stronger than those predicted by quantum electrodynamics as a consequence of Casimir effect and vacuum polarization. The intrinsic limits of propulsion applications of these effects are discussed in Sect.…”

“…The reasons why we think that the gravitational vacuum fluctuations can be quite important at the practical level and even responsible for the anomalous effects described in [14] and for the exchange of momentum with the vacuum at the microscopic level have been explained in [13]. Let me recall them here briefly.…”
