The mini nautical wind turbine Philéole “Grain Blanc” designed especially for sailboats.

The Philéole “Grain Blanc” vertical axis wind turbine is designed for sailboats and revolutionizes on-board energy. 

Advantages of the “Grain Blanc” wind turbine

For electricity production at sea and at quayside, all year round. 

Quiet : Savonius type, the three-bladed “Grain Blanc” wind turbine has a vertical axis. The peripheral speed at the tip of the blade does not exceed that of the wind, which prevents any whistling.

Vibration-free and turbulence-free: the choice of using three blades instead of two and their helical design made it possible, through wind tunnel testing to support, to avoid vibrations.

Lightweight and efficient : the very special design of the blades and air outlet vents, covered by patent, makes the propeller of the “White Grain” light and efficient. Its low weight only results in low tipping torque, even in a raised position on the mast.Strong and resistant: the one-piece construction propeller is made of recyclable PLA (corn starch). Its design is thick and rigid in the center, more flexible towards the periphery. It reduces centrifugal forces to better cope with turbulent winds. the “Grain Blanc” has been tested in a wind tunnel up to winds of 25 m / s (90 km / hour, 48 kn) without damage or significant loss of performance.

Safe : the low speed at the tip of the blade and the reduced inertia of the propeller (weight: 4kg) prevent any danger for the user as well as for birds or insects.

Reliable and space-saving : its vertical axis makes electricity production more regular because it is independent of the direction of the wind and vortices. Its small dimensions allow mounting at the top of the mast.

No coupling : 100% of the electricity production is sent through the connection cables


How does our vertical wind turbine work?


At sea

The Philéole “Grain Blanc” wind turbine covers basic energy needs in navigation: lights, radar, VHF radio, GPS, navigation center, computer, lighting, etc.


At the berth

Durant tout l’hiver, l’éolienne “Grain Blanc” maintient les batteries parfaitement chargées et prêtes pour partir en navigation, tout en permettant de faire fonctionner un déshumidificateur.
