There are several operational factors and requirements that have guided design and development of composite wind turbine blades over the last 20 years. The most important factors and requirements are ...

Everyone’s owned a pinwheel at one time or another. I remember riding in the back of my parents’ car, sticking my pinwheel out the window as we traveled down the street. The speed at which the ...

Develop a longer wind turbine blade that will produce more power output without increasing blade weight, the load on the turbine or the costs for transportation to and assembly at the wind farm site.

Folding, modular rotor blades designed for giant wind turbines By Chris Wood January 28, 2016 The huge wind turbines are designed to fold up to avoid taking damage in high winds Sandia/Trevor Johnston ...

The combed-teeth structure of Siemens’ new low-noise DinoTail aerodynamic blade add-on mimics an owl wing’s trailing edge fringe. For comparison, an un-combed blade is shown on the left. Following ...

In this last column in our Earth Day 2013 series, IPWatchdog wants to take a look at some of the research and development coming out of one of the industry leaders in wind energy technology, General ...

Researchers at Oak Ridge National Laboratory developed a low-cost carbon fiber that could lower the cost of blades for wind turbines. The fiber begins as widely available raw material used in the ...

Ontario, Canada has carved out a niche for itself as a hub of green technology. One of the latest clean tech innovations to come out of that province is DARWIND5, a vertical axis wind turbine (VAWT).
