Autonom arbeitende Sogturbine

Zielsetzung
Hier wird die Konzeption eines Motors beschrieben, der nutzbare Kraft liefert ohne entsprechende Zufuhr von Energie - in herkömmlichem Sinne. Selbstverständlich kann keine Energie ´produziert´ werden, wohl aber kann vorhandene Energie für einen bestimmten Nutzen verwendet werden. Die hier genutzte Energie ist die Kraft der normalen molekularen Bewegung in einem Fluid.

Zunächst werden einige bekannte theoretische Überlegungen und Erkenntnisse angesprochen. In einem zweiten Teil werden einige Maschinen bekannter Erfindern dargestellt, die zumindest ansatzweise arbeiteten. Danach wird der entscheidende Effekt dieser Konzeptionen heraus gearbeitet. Basierend auf diesen Prinzipien sind wirkungsvolle Maschinen in vielerlei Ausführung zu realisieren. Einige Varianten davon werden hier vorgestellt.

Very briefly, Schauberger engineered several types of machines that would create an up-current of axially-spinning air so powerful that the up-current's drag force would speed the whole machine higher and higher into the air. Of the many different types of air turbines he made several of them boasted a thrust force of nearly 10,000 bhp - simply by moving air. Some designers have utilised Schauberger's special turbines for flight and new research suggests that there indeed is a strong case for the continuation and re-establishment of Schauberger's research into these hugely beneficial technologies.

Central to any understanding of Schauberger's levitating force is his use of the cycloid-space-curve, which initially he used to generate a dual flow of fluid through a pipe (see note 1) - of an inner axial flow which moved faster through the pipe than did its peripheral flow which was especially directed into a cycloid path next to the pipe wall (see Schauberger's patent 134543).

To better understand the fluid forcing produced by fish when they are swimming it is necessary to first discuss the basic concept of a vortex and vorticity. A vortex arises when flow encircles a central point. Examples of where vortices occur in nature include: whirlpools, tornados, ocean eddies, blood flow through heart valves, and flow swirling behind rocks in a river current. Vortices appear in engineering fluid applications as well: flow around offshore platforms, tip-vortices from aircraft wings, helical vortices in propeller wakes and helicopter rotors. In general, vortices can form when flow passes any object with a non-streamlined shape or a sharp corner, and separates from the body.

" A local man (Dallas) developed a closed system engine that was purported to generate 350 HP and run itself. The engine weighed about 200 pounds and ran on cooking oil at temperatures of 300 F.

It consisted of a cone mounted on a horizontal axis. The shaft which supported the cone was hollow and the cone had spiralling channels cut into it. These spiralling pathways wound around the cone terminating at the cone base in the form of nozzles (rimjets).

When fluid was pumped into the hollow shaft at pressures ranging from 300-500 PSI (pounds per square inch), it moved into the closed spiralling channels of the cone and exited from the nozzles. This action caused the cone to spin. As the velocity of the fluid increased, so did the rotational speed of the cone.
