Wind sticks?

I came across an article about windstalks that generate power when the wind sets the stalks waving. They are looking into this to help eliminate bird kills from the blades of turbines, and also to help reduce the noise that they generate. Plus the stalks are more aesthetically appeasing then there counterparts. It's nice to see that people are not only trying to help our environment but also trying to improve the looks for the residents that have to live near these power plants. They are planning a to have a park inside of the windstalks field where people can walk around the stalks. And at night the stalks are to light up with led lights at the top of each stalk.
