The event, attended by local players, investors and industry representatives, highlighted a promising technology: flying wind turbines, inspired by the kite principle, capable of generating electricity without the constraints of conventional wind turbines.

Unlike land-based wind turbines, often criticized for their noise and impact on the landscape, Wind Fisher's system is based on an energy balloon connected to the ground by cables. Controlled by intelligent winches, the device flies at altitudes of between 50 and 500 meters(where the wind is up to 80% more powerful), describing figure-of-eight trajectories to harness the wind's energy. Electricity is generated on the ground, via a generator integrated into the winches, which limits the environmental footprint and noise pollution.

"Our technology does away with 100-meter masts and noisy blades, while using ten times less material per kW produced," explains Garrett Smith, co-founder of Wind Fisher. "This is an ideal solution for remote sites, islands or rural areas, where grid connection is complex or expensive. "

The inauguration of the Magnus airborne generator (MAG) prototype - a double balloon with a 15-meter wingspan - took place on November 4 at the Transpolis site, a motor racing circuit in Saint-Maurice-de-Rémens dedicated to crash testing road safety equipment.
