Wind Energy For Everyone

Our dynamic wind sail enables the self-sufficient production of wind energy in urban areas.

to our CROWDFUNDING

our mission

We want to use the power of wind to reduce CO₂ emissions and nurture climate protection.

Every breeze holds an opportunity - with the wind sail


Our wind sail power plant, or wind sail for short, imitates the rhythmic vibrations of treetops in the wind. Inspired by this natural model, the wind sail can be installed both at ground level and on building roofs and can provide renewable wind power all year round.


Our internationally patented innovation sets itself apart from conventional small wind turbines with rotors due to its simple operating principle and high yield efficiency in urban areas. Our technology does not depend on high, consistent winds, but captures any form of wind. It does not generate any infrasound and is environmentally friendly.


The pre-series of our power plant will deliver an annual energy production of 10,000 kWh or more.

Our innovation briefly explained

Phase 1

The wind reaches the sail and lifts it.

Phase 2

Electricity is generated via the generators at the end of the moving ropes.

Phase 3

The sail swings back to its starting position and the cycle begins again.
