New tech lets air traffic systems tell the difference between airplanes and wind turbines

By - November 30, 2012 1 Picture
Wind farms and airports don’t mix. Unfortunately, when the blades are turning on wind turbines, the motion can interpreted as aircraft on air traffic control radar screens. Needless to say, the results of such confusion could potentially be catastrophic – or at the very least, they could make things much more stressful for already-frazzled air traffic controllers. UK tech firm Aveillant, however, claims that its Holographic Radar system is the solution to the problem. Read More

World-first wooden wind turbine starts spinning in Germany

By - November 14, 2012 6 Pictures
Getting a wind turbine to a decent height to allow it to reach stronger winds than those found closer to the ground generally means sitting them atop a tower. Despite the eco-credentials of wind turbines, these towers are usually constructed from steel, which is not only expensive, but requires large amounts of energy to process. In an effort to make wind turbines even greener, German company TimberTower has erected a wooden 1.5-MW wind turbine in Hannover, Germany. Read More

DARWIND5 wind turbine improves on an old design

By - October 30, 2012 4 Pictures
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). Designed by Harvistor, it comes with a promise of more oomph than existing models for small-scale wind power generation. According to the company, recent tests showed that its technology can achieve 35 percent more kilowatt hours per year than current VAWTs for the same sweep area, besides operating at 25 percent lower heights than similarly priced market leaders.

Portable Power Center wind turbine fits into a shipping container

By - October 20, 2012 16 Pictures
Wind turbines have the potential to be very useful in providing renewable power to remote communities which have little or no infrastructure. Unfortunately, larger turbines tend to require a relatively involved set-up, with specialist gear needed to construct and maintain the turbines. The Portable Power Center (PPC) by Uprise Energy innovates in this regard by providing a self-contained unit which folds within a shipping container, and can be transported by truck. Read More

Vestas increases capacity of massive V164 wind turbine

By - October 3, 2012 2 Pictures
Danish wind turbine specialist Vestas was already looking to claim the title of the world’s largest offshore wind turbine with its proposed V164 that boasts a diameter of 164 m (538 ft). The company claims the V164 was developed with the potential of increasing its turbine size and now it has done just that, upping the capacity from seven to eight megawatts. So not only is the V164 set to boast the largest swept area of any single wind turbine, it will also claim the title for the world’s largest capacity wind turbine. Read More

WWII veteran creates bird-friendly wind turbine

By - September 2, 2012 17 Pictures
World War II veteran Raymond Green, an 89 year old resident of Jackson, California, has created a working prototype of a "bladeless" wind turbine which is bird and bat-friendly, and very quiet in operation. Though still in development at present, Green intends his design to be produced in various sizes, from smaller personal versions to much larger turbines which could be implemented in wind farms.
