NHEOLIS technology is the result of three years or research and development. The nheowind design, tested in the CNRS (French National Center for Scientific Research) wind tunnels, capitalizes on the Bernoulli principle that governs the conservation of energy in fluid dynamics. The effect of pinching a pipe is fully exploited on the nheowind structure leading to an acceleration of fluid speed on one side of the blade, and an increase of pressure on the other. The semi-conical blade shape is mounted with optimized deflection angles adjusted for an efficient use of the kinetic energy of the airflow.
 

The design was modeled with the French Aerospace Lab ONERA resulting in the improved nheowind 3D100 and nheowind 3D50 design featuring a curved blade better retrieving the wind in its trajectory.




Harnessing wind energy in 3D, this design generates power quietly, and extracts more power from the wind.

The compact structure high resistance can resist powerful gusts up to 50 m/s, or 180 km/h, achieved with shrouds maintaining the blades all over their length.
