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, ...

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.

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 ...

Crowdfunding has come to the small wind generation field with an Indiegogo campaign intended for an interesting target niche: a small wind generator designed to be clipped onto solar panels. According ...

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 ...
