There are several operational factors and requirements that have guided design and development of composite wind turbine blades over the last 20 years. The most important factors and requirements are ...

A new wind turbine blade design that researchers at Sandia developed in partnership with Knight & Carver of San Diego should significantly reduce the cost-of-energy of wind turbines at low-wind-speed ...

Everyone’s owned a pinwheel at one time or another. I remember riding in the back of my parents’ car, sticking my pinwheel out the window as we traveled down the street. The speed at which the ...

Discover the future of wind energy as we compare traditional horizontal-axis wind turbines (HAWT) with the innovative IceWind vertical axis wind turbine (VAWT). This video explores the key differences ...

For decades, companies eager to boost wind energy production have relied upon a simple strategy: make the turbine blades bigger. While generally effective, the approach has drawbacks. Namely, bigger ...

Drag-based wind energy design. Aiming to translate its expertise in manufacturing monocoque, ribbed components with thermoplastic microspheres, Xenecore is working to develop a fan-shaped, drag-based ...
