There was a time not so long ago that seeing a single wind turbine spinning in the distance was a novel experience for most people. Not so much any more. There are now hundreds of wind turbines ...

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 ...

Wind power has always been a trade off between clean energy and the visual, acoustic, and ecological cost of giant spinning blades. A new generation of radical designs promises something different, ...

Wind turbines that swap traditional mechanical drivetrains for hydraulics could potentially be lighter, more reliable, and less expensive than those fielded today. • A nacelle-mounted hydraulic ...

Renzo Piano’s Dragonfly Wind Turbine, with two blades, in partnership with ENEL Green Power, marries clean design to nature’s efficiencies. In Pisa, it also has been put to the proof to prove to all ...

One problem when you try to field super-big wind turbines: All the components involved get super heavy as well. No surprise, then, that there are efforts afoot to figure out ways of lightening up the ...

Computer modeling technologies are being developed to help engineers design better machines. The models are being applied to wind turbines, artificial hearts and gas turbines. Three thin leaflets blew ...

LONDON - Time To ACT plc (AQSE: TTA), an engineering group specializing in energy transition technology, announced today that its subsidiary, GreenSpur, has developed a preliminary design for a 15MW ...

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 ...

For many environmental enthusiasts, horizontal-axis wind turbines (HAWTs) — the kind that look like windmills slowly spinning in the distance — are a pretty familiar sight. Unfortunately, there are ...

When you think of a wind turbine, the image that likely pops into your mind is the classic three-bladed giant rising from farmland or the sea. But over the years, designers and engineers have come up ...
