Blade Runless?

A Madrid-based company have invented a source of wind power without blades (https://www.theguardian.com/environment/2021/mar/16/good-vibrations-bladeless-turbines-could-bring-wind-power-to-your-home). The 3 metre high 'Vortex Bladeless' towers, just vibrate in the wind to generate electricity (like these humanoid balloon figures you sometimes see at sporting events?). The Vortex Bladeless has have already attracted the attention of Norway's Equinor Company. Clearly, adoption of bladeless wind power devices, would be good news for bird populations. Seeing these 'skyvibrators' wriggling on the hillsides might, however, be a bit strange at first.
