sunlitrevolution:Bladeless wind turbines generate electricity by shaking, not spinningScientists hope to hugely reduce the cost of wind energy by removing the blades from wind farms, instead taking advantage of a special phenomenon to cause the turbines to violently shake.Vortex, a startup from Spain, has developed the tall sticks known as Bladeless — white poles jutting out of the ground, that are built so that they can oscillate. They do so as a result of the way that the wind is whipped up around them, using a phenomenon that architects avoid happening to buildings and encouraging it so that the sticks shake.They do so using vortices, which is where the company gets its name from. The bladeless turbines use special magnets to ensure that the turbines are optimised to shake the most they can, whatever speed the wind is travelling at.As the sticks vibrate, that movement is converted into electricity by an alternator. -- source link
