These Bladeless Turbines Cost 40% Less to Maintain
You’ve most likely seen a wind turbine in your lifetime. They’re essentially gardens of huge fans that spin to produce energy and although they’re efficient already, a start-up in Spain has improved their design impressively.
Instead of using the blades, Vortex aims to use friction. They build large unstable beams that shake as the wind blows and magnets in the beam to adjust the wind volume’s frequencies. This creates energy by vibrating an alternator in the base of the bladeless turbine.
The bladeless turbine would cost about 40% less than ones with fans and use less room. They also require less maintenance and come in various sizes, plus a bonus is that they’re silent and very cool looking. Check them out yourself.
