'Wind Lens' Boosts Efficiency of Wind Turbine Blades

Researchers at the University of Kettering in Flint, Michigan are assessing a "wind lens"  they say improves the efficiency of wind turbine blades. As reported on the university’s website, the innovation significantly boosts a wind turbine’s capacity to generate power.  
Dr. Ahmad Pourmovahed explains that by encircling the three blades of a typical wind turbine with an outer perimeter ring that connects the blades, the efficiency of the turbine can be improved by up to 50 percent. He stresses that the idea is not a new one, but says it has not been studied in large-scale turbines outside the lab.
Pourmovahed presented the findings, which were based on a project initiated by four of his students, at a conference in Pisa, Italy in May of this year.
