If ordinary air is bio-centrifugated above the speed of sound in very specially contoured and suitably alloyed development-facilitating devices, for which an auxiliary mechanical force is required in the order of 0.08 kW per cubic metre of moved air, then the torque-producing current (synthesising current) mentioned above arises, which also accelerates the device that generates it. This further accelerates the intake of air, which again intensifies the strength of the current, resulting in an even higher rate of rotation, which provokes yet a further increase in the torque-producing current, and so on. Ultimately a powerful and highly potent vacuum is created in front of the generating device, while at the same time the expansive pressure described above exerts a squeezing, wedging pressure along its teardrop-like body (see figs. 22[6] & 38). These suctional and pressural forces, which evolve along a common developmental axis in the form of a fully developed dynagen gradient can overcome any weight or form of anchorage.
