Link: KUCB Unalaska is windy, and that wind can come from any direction, given the city's Aleutian location and the mountains that surround it. Two residents are trying wind turbines made by Helix Wind Corp. Instead of propeller-like blades, the company's turbines use "drag bucket" design that lets them grab wind that swirls from any direction and at speeds that might damage a traditional turbine blade.
