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 ...

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 ...

A design firm from New York, Atelier DNA, has developed a concept that uses cattail like stalks instead of traditional turbine blades for harnessing the power of wind. Planned for the city of Masdar, ...

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 ...

Virtually every week there are articles about new and innovative methods for harvesting wind energy. And every week more megawatts of capacity from three-blade horizontal-axis wind turbines (HAWT) ...

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 ...

Since childhood, Michael Carruth, a junior in the environmental design program at CU-Boulder, has been fascinated with nature. Long hours spent playing outdoors, observing swirling leaves, clouds ...

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 ...
