Cross-flow turbines, also known as vertical-axis turbines, are attractive for power generation from wind and water currents. Some cross-flow turbine designs optimize unsteady fluid forces and maximize ...

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 ...

GKinetic Energy has been granted a US patent for a blade pitch control arrangement designed for its vertical-axis ...

In order for wind turbines to function effectively across wide ranges of wind conditions, you’ll need what’s known as blade pitch control. Lucy Pao, the Palmer Endowed Chair Professor in the ...

Engineers at Moog Inc. and wind turbine maker Made Tecnologias Renovables SA have produced a pitch control servo valve that governs blade pitch while eliminating external controls. The valve provides ...

Engineers at Purdue University and Sandia National Laboratories have developed a technique that uses sensors and computational software to constantly monitor forces exerted on wind turbine blades.

To lower the cost of energy from wind turbines, designers have focused on the power-generating capacity of each turbine. They have raised tower height to place turbines in stronger winds and ...

Each year a panel reviews papers nominated from the past two years and selects an article of high significance. The paper, published in 2022, describes the first experimental implementation of Model ...
