A Spanish company built a bladeless wind turbine that sways instead of spinning, turning the vibrations caused by wind into electricity

For decades, wind turbines have followed the same basic design: towering structures fitted with enormous rotating blades that convert wind into electricity.

As manufacturers compete to build ever-larger turbines with blades stretching more than 100 metres, one Spanish company has taken a completely different approach.

Instead of spinning blades, its device is a slender vertical mast that oscillates with the wind to generate electricity.

Developed by Vortex Bladeless, the technology weighs only a fraction of a conventional turbine and has no rotating blades at all.

Although current prototypes generate far less electricity than utility-scale wind turbines, researchers believe the concept could offer new possibilities for small-scale renewable energy in places where traditional turbines are impractical.How does the bladeless wind turbine work without spinning blades?According to the Engineering College of Science and Technology, unlike conventional wind turbines that rely on rotating blades, the Vortex Bladeless device generates electricity through vortex-induced vibrations.
