Bladeless Turbine Could Spark Wind Power Revolution

A long pole with a rotating disc-shaped head is operating in the airstream at the beach at Raoued, a coastal suburb of the Tunisian capital.The strange machine moves frenetically as the wind blows.

Anis Aouini is the Co-Founder of Saphon Energy – Saphon is an old Phoenician word that means “wind” – and the inventor of this instrument.It is called a Saphonian, and it is a bladeless wind turbine.

Saphon’s aim wasn’t to improve the current wind turbines technology but rather to challenge the “box” and develop a radical new way of harnessing the wind.


Anis’ basic idea was to remove the whole rotating system (blades and hub) and to replace it by a non-rotational sail-shaped body.

The idea has evolved over time and emerged as a promising technology named the Zero-Blade Technology. The related wind converter, baptized “The Saphonian”, is bladeless, rotationless, and follows, instead, a back and forth 3D knot motion, largely inspired from sailboats.
