COMPOSITESWORLD - Off-grid turbine: Helix in the wind

This new composite twist on the vertical-axis wind turbine makes no small impact on the private power market.

Engineering Challenge: 
Adapt the Darrieus-type vertical-axis wind turbine design to optimize wind energy capture capabilities, decrease noise and improve aesthetics for commercial and residential markets.

Design Solution: 
Add a helical twist to the vertical blades to optimize wind capture, create axis-within-axis to segregate weight bearing and turning structures, and integrate composites in blades, the core and support arms to minimize weight.
