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 5 times more powerful than at 100m

our radically simple design offers a continuous, reliable source of energy:

  • in the sky: wind force is captured by a simple, light, efficient kite
  • on the ground: mecanical force is converted to electricty (machinery and electrical generator)

Magnus effect

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

we use the aerodynamics of our unique, patented spinning cylindrical kite:

  • the high-speed rotation (300 rpm) induced on our flying kite generates the Magnus effect
  • the resulting force pushes the kite sideways, hence pulling the cables of our system

Lighter-than-air

the kite is filled with helium, making it lighter-than-air, easy to deploy and maintain

this innovation allows a crash-proof, automated continuous flight:

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