We are a startup team of passionate engineers who got tired of waiting for green energy to work around the clock. So we built something new: a frictionless, ultra-efficient windmill that fits on unused chimney stacks and generates power even when the wind barely whispers.
The Challenge
Solar panels go dark at night. Conventional wind turbines stall when the breeze drops below their minimum speed threshold. This means that during winter months and overnight hours — exactly when energy demand peaks — renewable sources often fall silent.
As developers living in the Netherlands, we experienced this gap first-hand. High electricity bills, heavy reliance on fossil-fuel backup grids, and a sense that the industry had stopped innovating. That frustration became our fuel.
Together with leading research institutes, we set out to engineer a windmill that simply never stops — regardless of wind speed, time of day, or season.
Our Design Concept
Our design draws from decades of vertical-axis wind turbine research. By combining the self-starting torque of the Savonius rotor with the aerodynamic lift of the Darrieus configuration — and wrapping it in a smooth helix profile — we achieve what none of these designs could accomplish alone.
The elegant curved blades of a Darrieus turbine generate powerful aerodynamic lift at higher wind speeds. We incorporate this outer blade configuration into our design, dramatically boosting energy output as wind speeds increase — all while maintaining the compact, chimney-friendly footprint.
Urban Infrastructure
Across Europe — there are thousands of unused chimney stacks sitting idle on rooftops. Once essential for heating, today they serve no purpose. We see them differently: they are ready-made installation points for clean energy generation.
Our windmill is engineered to mount directly onto existing chimney infrastructure. No new foundations. No planning permits for new structures. Just a clean, vertical turbine where a chimney pot used to be — quietly generating power day and night.
The elevated position of a chimney also means our turbines are above rooftop turbulence, accessing cleaner, faster, more consistent airflow than ground-level installations.
