This is due to a type of turbulence called Wake Galloping, caused by airflow creating lift on the lee-side of cylinders (or cables on suspension bridges.) Now researchers in South Korea have developed a way of harnessing the turbulence to generate electricity. Their device works most efficiently at wind speeds too low for conventional wind turbines."
