The article itself has almost no information on the actual technology. The embedded video is much more helpful, and explains how the "lens" around the turbines helps to disperse air and create a low pressure zone on one side of the turbine. The relatively higher pressure air on the other side naturally wants to push through, greatly increasing the efficiency of the turbines.
