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, ...

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 ...

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 ...

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 ...

Norway's World Wide Wind has a radically different take on offshore wind power. These floating, vertical-axis wind turbines feature two sets of blades, tuned to contra-rotate – and they promise more ...

Forbes contributors publish independent expert analyses and insights. Llewellyn King has been a player in the energy space since 1970. Jimmy Dean, the country musician, actor and entrepreneur, ...

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.

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 ...

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 ...
