[10] Tractive force: This refers to the force described hydraulically as 'Shear force' — the force that acts to 'shear off' or to dredge and dislodge sediment. In German the term for shear force is 'Schubkraft', meaning 'to push, to shove' as well as 'to shear', whereas Viktor Schauberger uses the word 'Schleppkraft'. The verb 'schleppen' means to drag, draw or pull. Viktor Schauberger's choice of 'Schleppkraft' here is quite specific, since in his view the movement of sediment is due to the sucking action of fast flowing, dense cold water downstream, rather than to the mechanical impact of the water coming from upstream. In view of this subtle change in emphasis, in lieu of the hydraulically correct term 'shear force', the term 'tractive forces' will be used. This dynamic is similar to the effect of wind on roofs, where a roof is blown off not by force from the windward side, but rather by the sucking effect of vortices created on the leeward side. -Ed.

Therefore if the media of water or air are moved naturalesquely (and the trick is how to do this) then the bipolar gases are initially transformed into aetheric and ultimately into energetic stocks of subtle matter. These are then bound in the self-evolving juvenile media (air and water) and what has been increased in this way is rendered homogenous and specifically densified. That is to say, they intensify the carrying capacity and tractive force to such a degree that in such waters material with a higher specific weight than the transporting medium, even ore with a specific weight of 1.9, readily floats down the centre of the axis, where the strongest suctional force acts downstream and the strongest reactive force acts upstream in the form of a dynagen gradient, but which, however, has no effect on raw material structures to the extent that these do not involve life-forms.

which in turn the allotropic[1] primary materials for growth and development also reside. Reacting to bio-centrifugence, these basic substances are liberated through the cycloid-space-curve-motion of the Earth and under the influence of reactive cooling substances, consume (bind) the counter-weighing oxygen. Reactive differences in potential are created in this way which express themselves as reactive differences in temperature, which on their part, as all-penetrating inner outward<->inward, upward<->downward dynamic influences, intensify the physical (external) form of movement. This leads to a renewed intensification of the inner dynamic processes, which once again act to stimulate additional motion. Thus it is absolutely no wonder that the good old Earth eternally rotates about her peculiarly unique axis, because in this special axis (viz. the shimmering shaft in a water vortex) that something ascends, which enables stationary trout to stand motionless amidst torrential flows and to flee upstream like lightning. A phenomenon inexplicable in terms of mechanics, because the trout must not only overcome its own weight, but also that of the counter-flowing dense and heavy spring water. Indeed it can escape upstream all the more rapidly, the faster the cold specifically heavier water-masses, which whirl about their own axes in exactly the same way that the Earth rotates about hers, enter its jaws and flow out of its gills through a system of cycloid-space-curves. In this way the particular axis is formed in which that something returns to its ur-source, which becomes free through this special rotating motion and the frictional motion produced by it. In becoming free in this way, it then draws the motion-generating form - in this case the trout - in its wake, because this counter-flowing energy-form is the force that enables everything that crawls and flies on this manure-heap Earth to overcome its own weight. In other words, it is the 'levitational force', without which there would be no life, no movement, no growth and naturally no gravitation either.

Conversely, similar formative and levitative energies are created in front of the intake through primary processes of synthesis. These, for example, enable the trout to stand motionless in torrential streams, or to flee like lightning upstream when danger threatens. This is a phenomenon that cannot be explained mechanically, because the free-standing trout must not only over-come its own body-weight, but also the weight of the oncoming water. It overcomes this all the more easily, the more rapidly and torrentially the water containing these valuable threshold suspensions flows, which are reactivated [The Energy Evolution - Harnessing Free Energy from Nature, The Economy Founded on Reactively Produced Energy]
