Forward through the conduit.
The current advances from inlet to outlet. A pressure difference or elevation head drives the flow through the system.
The Spiral Conduit · Viktor Schauberger
A current
within a current.
A straight passage. A turning current. Schauberger’s guide vanes give water a spiral path—and a smaller spiral within it. Open the conduit and follow the idea from its first turn.

Follow a peripheral strand: it travels around the pipe’s axis while turning around its own smaller axis. This nested movement is the “double spiral.” The central stream continues along the conduit inside that moving envelope.
Illustrative reconstruction after the patent figures and the flow diagram in The Water Wizard. Geometry, particle paths and animation speeds are schematic. The moving points mark parcels of water.
01 / The movement
One spiral carries another.
The pipe gives the water a boundary. Its internal surfaces give the moving water direction. Schauberger arranged curved guide vanes along several helical rows, with each surface turning part of the current inward from the wall. The first patent sets out that arrangement. [1]
The later patent gives the vane a twist, like a wood shaving. Its two cooperating surfaces separate a peripheral strand from the central current and give that strand an additional rolling movement. The strand follows a helix while turning within it. [2]
A helix around the main axis.
The guide surfaces redirect part of that movement around the pipe’s length. Forward travel and rotation combine into a helical path.
A smaller turn inside the first.
In the double-spiral arrangement, peripheral strands also roll around their own smaller axes. “Double” describes these nested scales of movement.
02 / The objectA small surface changes
A small surface changes
the encounter.
Curved toward the centre.
The early design describes ploughshare-like surfaces extending from the wall. Their curvature redirects approaching water toward the central region.
Twisted along the flow.
The supplementary design develops two working faces from a twisted plate. One directs and separates; the following face imparts the secondary turning motion.
Repeated along a helical row.
The individual vane belongs to an arrangement. Its position along the pipe coordinates the next encounter between the moving water and a guiding surface. The patent also describes ribs or fluting on the faces. [2]

Schauberger wanted a conduit to participate in water’s development as it carried it. In his description, a central current travels within a surrounding envelope of rotating strands. He associates the core with cooling and the peripheral region with interactions at the wall.
He then places this motion within his oxygen–carbone account: oxygen concentrates toward the periphery, while the central current becomes associated with the maternal “carbones.” Their encounter, in his telling, develops the water’s qualities along its journey. The language of Father & Mother becomes a theory of conduit design. [3]
He also envisaged transporting materials heavier than water along the central stream. His proposal joins three ambitions: guiding the current, carrying its material cargo and maintaining the quality of water during transport. The guide vane is the small physical intervention through which he sought to organize all three.

Read the whole circuit.
Where does the water go?
Follow the core and peripheral paths separately. Observe where water turns inward, how much it rotates, and where particles collect. The three model layers make those spatial relationships visible.

What does that movement require?
A practical comparison uses the same pipe length, diameter, water temperature and inlet conditions. Record discharge and pressure difference, then examine how the guide surfaces change transport through the conduit.

A useful next step is a transparent conduit study: illuminate a cross-section, follow tracer paths, and compare the two vane arrangements. Keep the geometry beside the measurements so the relationship between form and movement stays visible.
