A new wind technology using wind belts rather than rotating turbines promises exciting prospects for aesthetic installations. I could see the adaptation of this idea for a LAGI installation. Modules of Humdinger energy producing armatures as the medium for a new public art and sculptural form!
Instead of using conventional geared, rotating airfoils to pull energy from the wind, the Windbelt(tm) relies on an aerodynamic phenomenon known as aeroelastic flutter ('flutter'). While the the phenomenon is a well-known destructive force (e.g. a cause of bridge failure), researchers at Humdinger have discovered that it can also be a useful and powerful mechanism for catching the wind at scales and costs beyond the reach of turbines.
Sketch examples of the technology employed on a large scale can be found on Humdinger's website.
