Wind turbine observation tower

The author of this is proposal is Michael Jantzen. This is an observation tower where people can walk through to view the surronding landscape, while the five wind activated segments of the structure rotate aroud them in diferent directions.

 While these segments rotate, they also produce electricity which is used to light the structure at night. Here you have the link to watch more projects of this artist:  http://www.humanshelter.org/
