Most important updates

Current obstacles

Logistics and installation complexityOnly a few ports globally can handle 147-meter blade transport and deep-water installation of ultra-large components.

Physics limits

Structural strength of ultra-large rotor bladesAs rotors scale beyond 300 meters, blade deflection and fatigue become harder to manage. Material science and manufacturing precision set limits on practical rotor sizes.
Floating foundation costsDeep-water offshore turbines require floating foundations that cost significantly more than fixed-bottom designs, limiting deployment to specific regions with deep, stable seabeds.

How it works

3 parts

Rotor

300-meter sweep with efficient blades

147-meter composite blades achieve 0.49 wind energy utilization coefficient, capturing more energy per diameter meter.

Offshore Design

Deep-water installation

40-meter water depth installation off Fujian, designed to withstand typhoons and salt-corrosion.

Monitoring

Autonomous operation with safety systems

LiDAR and blade load sensors enable unattended operation with real-time monitoring and autonomous shutdown.
