Our solution
Wind-Fisher’s answer is to make Airborne Wind Energy not just a concept but a reality. Our patented concept is a lighter-than-air, helium-filled, rotating wing rotor that harnesses the aerodynamic Magnus effect.
Lighter
20 times less weight than
an equivalent wind turbine
Safer
Smooth takeoff and landing due to lighter-than-air design
Faster to deploy
Rapid permitting
and minimal ground infrastructure
Cost effective
Target LCOE ~
0,04 €/kWh
Everywhere
Suitable for
low to high
wind regions
The Wind Energy challenge
The total amount of economically extractable power available from the wind is considerably more than present human power use from all sources
Currently, wind power supplies 7% of the electricity, worldwide, mainly in very large wind farms, operated by large utilities
Our belief is that wind energy should be available for smaller, local users. The demand for decentralized renewable energy (100 ~ 1000 kW) is growing fast worldwide
But
Classic wind turbines require a high CAPEX (60 M€ on average per wind project)
Classic wind projects have a long project lead time (7-10 years on average from start to end)
Classic wind turbines have a high environmental footprint
Classic wind energy has a poor load factor, impacting efficiency
Our cylindrical MAG is very safe by design in all flight conditions, compared to other airborne wind energy concepts. Being lighter than air, take off and landing is smooth and safe. The cylindrical design gives it significantly better gust and turbulence tolerance, compared to kites or rigid wings. In addition, our efficient structural shape leads to lower overall material costs for a given power.
The aerodynamics of the MAG lead it to having a greatly reduced noise impact compared to traditional wind turbines. Regarding visual pollution, when there is no wind, the MAG is simply returned to the ground station and disappears from the landscape.
