Student makes wind turbines quieter

Stefan Oerlemans, a student from the University of Twente, discovered a way to reduce the ‘noise source distribution’ of modern wind turbines. For those of you who may not know, people living near these wind turbines have to deal with the loud ‘swishing’ sound they make. Yes, there are downsides to green energy.

Oerlemans figured out that the sound level could be reduced by half by fitting jagged edges, or teeth on the blades of the turbines. Now all I need is some black, red, yellow and orange to paint some flames and make them look cool as well.
