Humanity has been harvesting energy from the wind for centuries. The practice goes back at least to 8th century Persia where the first known historical records of windmills came, but likely extends ...

What is wind power density? The different types of generators used in wind-turbine systems. What architecture is most commonly used in high-power wind-energy-conversion systems (WECS)? Fundamental ...

The world's strongest winds race high in the sky, but that doesn't mean they're out of reach as a potentially potent energy source. Flying, swooping and floating turbines are being developed to turn ...

Shawn Frayne’s Windbelt uses vibrating ribbons, not blades, to harvest wind efficiently on a smaller scale where traditional ...

Has affordable, practical home wind power generation become a reality? The Honeywell Windgate wind turbine from EarthTronics looks like it could be a contender. Developers EarthTronics and Honeywell ...

Researchers have modeled the fluid dynamics of multi-rotor wind turbines via high-resolution numerical simulations. The simulations demonstrate a clear advantage for a turbine model with four rotors.

High above the streets of Yibin City in southwest China, a helium-filled airship shaped like a streamlined Zeppelin has quietly become a functioning power plant. The S1500 system, described by its ...

When most of today’s wind projects were developed, first costs were the focus; operations and maintenance (O&M) costs were largely unknown. Now, with hundreds of turbine models in operation—sometimes ...

As Massachusetts races to meet its clean energy goals, will more wind turbines dot the ridge lines of the Berkshires? Ask Francis Pullaro that, and the president of RENEW Northeast starts to chuckle. ...
