Vortex Bladeless is a vortex-induced vibration resonant wind generator, in contrast to horizontal-axis wind turbines (HAWT) and vertical-axis wind turbines (VAWT) that work by rotation. Vortex''s innovation comes from its unusual shape and way of harnessing energy by oscillation; fiberglass and carbon fiber reinforced polymer mast oscillates in the wind, taking advantage of the emission of von Kármán vortices when a moving fluid passes over a slender structure. At the bottom of the
