Benefits of adding a second, smaller rotor to wind turbines Date: March 9, 2015 Source: Iowa State University Summary: Aerospace engineers are developing dual-rotor technology to improve the ...

They’re big, round structural pieces. They’re not shaped like an airfoil. And so they don’t harvest any wind, reducing a turbine’s energy harvest by about 5 percent.

What if one mathematical nuance has been quietly restraining the efficiency of wind turbines since the turn of last century?

Caption Researchers at the Technische Universitaet Muenchen have devised a way to monitor stresses on wind turbine rotor blades precisely and in real time. At the heart of their approach is a ...

Maintaining wind turbines and identifying potential vulnerabilities is expensive and time-consuming, especially when they are ...

The overall effect, says WCS, is a 500 percent boost in annual energy output, with each array making enough power to run 80,000 European homes.

Wind turbines are generally cost-effective, which is why they're one of the fastest-growing sources of energy in the world. For years, they've more or less been built the same way: with one rotor ...
