Schauberger’s Original Funnel

Design inspired by nature

The preferred flow of water can be easily observed in nature. Countless flow patterns can be seen, including large and small vortices. That is to say that the water moves in the form of a spiral. Based on this observation, the natural scientist Walter Schauberger searched for a form in which water is optimally curled. Schauberger’s hyperbolic funnels are the result of many years of research.

Walter Schauberger drew inspiration from Pythagoras and Johnannes Kepler, who were convinced that our universe followed harmonic principles. With the help of his mathematical calculations, Walter Schauberger went on to discover harmonic laws. In implementing these laws, he developed the shape of the hyperbolic cone in 1970 in collaboration with engineer Maximilian Mack, which was subsequently used as Schauberger’s hyperbolic funnel.

Since 1970, a lot of university research has been devoted to the scientific study of this funnel and much has been discovered. Current investigations concern the flow velocity, the pH value, the oxygen uptake of funneled water and there are always new and astonishing results (see link to master’s diploma below).

With selected Austrian craftspeople and the highest quality glass, wood and copper (Weinmayer’s Glassblowing, Füchsl’s Wood Design & Achleitner’s Goldsmith’s Workshop), we are now implementing Walter Schauberger’s findings. The result is a real eye-catcher. The glass funnel, visible from all sides, in an elegant wooden frame (choice of ash, pine or walnut) with a stylish protective copper cap refines your drinking water at home. A durable and sustainable designer piece “Made in Austria”, inspired by nature.

The hyperbolic shape has been used successfully for years with the original Martin water whirler, the Wytor acrylic hyperbola and the copper funnel for biotopes (see chapter “Practice”).

Walter Schauberger’s Hyperbolic Funnel: promising water treatment device

“Vortices in Hyperbolic Funnels as Aeration Systems”

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.

Official Viktor Schauberger Video on YouTube

The first film about Viktor Schauberger’s life’s work was published some years ago on DVD.
A comprehensive survey of historical facts, current research and various practical applications into both technology and the natural world.

As several unauthorized copies of poor quality appeared on the internet, the producer (J. Schauberger Verlag) and the director of the Film, Franz Fitzke, decided to publish the original documentation on YouTube via wocomoDOCS.
