While wind turbines are certainly effective at producing energy, some think they aren’t the most aesthetically pleasing structure to dot our open country-sides. But that’s no reason to write them off. In fact, Altaeros Energy has come up with a fascinating solution to this little problem: a donut-shaped wind-power structure fitted in a helium-filled balloon [...]

Even though the cost of wind power is in a continuous drop since 2008, more and more researchers aim for reducing it more while at the same time enhancing the efficiency. A couple of teams from the Syracuse University and the University of Minnesota have a few ideas about how to improve wind turbines by modding their blades and how the air flows on them.

As they say, details make all the difference when it comes to big things. Following this principle, the huge wind turbines that you see on fields all around the world, need small adjustments and a little intelligence to act efficiently. Called SpiDAR, a newly-developed system can predict where wind is coming from and is going to be a step ahead and over currently-existing monitoring systems.
