This documentary delves into the profound, nature-inspired engineering and ecological philosophy of Viktor Schauberger (1885–1958) and his son Walter Schauberger (1914 – 1994). It explores Schauberger’s central belief that nature operates on the principles of vortices and implosion — a force fundamentally opposite to conventional, energy-intensive centrifugal technology. The film argues that utilizing this vortex power is the key to achieving true ecological health and sustainable technological progress. The film showcases a global movement of engineers and thinkers who are successfully putting Schauberger’s once-dismissed, radical ideas into practice. From revitalizing major European rivers and protecting natural floodplains to innovating soil management in agriculture and developing revolutionary pumping technologies, the documentary demonstrates the power of Schauberger’s “180 degrees opposite” thinking.

A bubbling, clear mountain stream is the epitome of intact nature. As it flows around the stones, the water forms many small vertices, sucks in air and absorbs oxygen in the process. The vortex in the hyperbolic funnel does the same and creates a pulsating and beautiful structure of the water as it flows through, reminiscent of a double helix.

Nature-inspired reverse hurricane: water aeration quicker and cheaper

Researchers from the theme Applied water physics have discovered an efficient and cost-effective method of dissolving oxygen into water. An astonishing method that is five times more rapid and a lot cheaper than the conventional bubble-blowing aerations. By using a nature-inspired vortex, or whirlpool, the scientist could show the unthinkable and for decades unprovable. The patented method was published last week in the journal Water.

“An outstanding idea, three generations old, has finally been proven against even our own believes – the way nature dissolves air into water is more efficient and cheaper than what humans have been able to do in all of history,” explains corresponding author Elmar C. Fuchs, “oxygen in water is an essential element for producing drinking water and cleaning up wastewater.

Vortexing works by sending water around in a hyperbolic funnel shape – creating a suction effect through the middle of the whirl. This way, air is pulled into the water – like a reverse hurricane. The oxygen transfer rate in this setup is very much unlike those in the commercial bubbling method: we have consistently recorded a fivefold increase, but have seen much higher.”

Moreover, swirling the water through a funnel turns out to be cheaper. Fuchs: “Nobody believed us at first. It is the perfect scenario, cheaper and faster. Hyperbolic vortexing requires about 40 times less energy per kilogram of dissolved oxygen compared to other methods. With the correct flow regime in a hyperbolic funnel, the only energy required for this system is used for pumping the water up and into the system. Which is less intensive than otherwise required machinery and consist of fewer moving parts. It is that simple.”

But it was never proven before. “The idea has been around for a few decades, originating from the Schauberger family in Austria,” Fuchs tells, “three generations long the Schaubergers have been drawing inspiration from nature to develop technological advancements. Because they believe that the way nature does it, is the best way.” Now with the Wetsus physicists around, it was finally proven.

As of now, the technology is said to work great for making drinking water, as it is well able to oxidize the iron from the groundwater. A major milestone. Further advancements to aerate wastewater are on their way.

Master Thesis at TU Delft shows: higher gas transfer rates in comparison to the conventional aeration systems

• The author of the Master Thesis, Teja Donepudi, writes in his introduction:

“As opposed to other water treatment methods that use chemicals, aeration is an eco-friendly
method. In addition to being an essential step in wastewater treatment, it is also one of the
most energy-intensive processes consuming 15% to 90% of total electricity, and up to
40% of the operating budget. This has lead to a need to make aeration processes more
sustainable and economical. With their high gas transfer rates and low energy consumption,
vortices generated in hyperbolic funnels might be a promising alternative to the conventional
aeration systems presently in use.”

This numerical study is based on experiments, conducted with groundwater on pilot test facilities of hyperbolic funnels at the Water Application Center (WAC) in “Wetsus, European Centre of Excellence for
Sustainable Water Technology”, situated in Leeuwarden (NL), in cooperation with the University of Natural Resources and Life Science, Vienna (Universität für Bodenkultur, Wien), Technical University Graz and other research centers.
