Spanish company, Vortex Bladeless Ltd., has designed turbines that are entirely without blades. They generate electricity by jiggling.
The structure of these bladeless turbines works by attracting whirlwinds. Depending on the speed and direction of the wind, these whirlwinds develop at certain frequencies. At the base of the bladeless turbine are two rings of repelling magnets. When the wind pulls the turbine in one direction, the magnets pull it in another, causing the tube to wiggle.
Energy reaches a peak when the frequency of the vortex or whirlwind coincides with the frequency of the turbine. This peak is established due to the aeroelastic coupling that arises at this point. It is at this moment that the energy is absorbed and converted from kinetic energy into electrical energy.
To simplify, the whirlwinds produced by the wind cause the turbine to vibrate. This kinetic energy is converted into electrical energy and used to power our homes.
