time to move beyond the windmill.
modern physics bring wind energy to the new millenium.

wind power, reinvented

our technology

power the world with high-altitude wind

from 100 kW to 10 MW – the safest, most cost-effective, and truly scalable solution

High altitude wind

at 300 m, wind blows 24/7 and is 1.6x more powerful than at 100m

catching high altitude wind offers a continuous, reliable source of energy:

  • at 300m, wind blows faster and steadier than at 100m (traditional wind turbine height)
  • our system hence generates 1.6x more energy as power grows exponentially with the wind speed

Magnus effect

for the first time in History, the Magnus force is converted to electricity

our patented system is designed to harness the power of airflow:

  • we induce a high-speed rotation (300 rpm) on our flying wing to generate the Magnus effect
  • the resulting force pushes the wing sideways, hence pulling the cables of our system

Lighter-than-air

the wing is filled with helium, making it lighter-than-air and crash-proof

this innovation allows a safe, automated continuous flight:

  • no wind required for take-off
  • 100% automated take-off, operations and safe landing
  • designed to fly 3 months without maintenance

a truly scalable solution,
from 100 kW to 10 MW

a unique scalable design that adapts project of all sizes

our product scales to fit projects of all markets: from a small remote farm to a large wind farm for utilities

the key: no matter the project size, our product relies on the same three simple principles (high altitude wind, Magnus effect, lighter-than air)
