These bladeless wind turbines shake to generate electricity

Farms dotted with the gigantic spinning blades of wind turbines have become a standard sight on long-distance road trips, but what if there was another way to capture energy from the wind? A startup out of Spain is working on that very idea. The company’s called Vortex Bladeless, and its turbines look like stalks of asparagus poking out of the ground.

Instead of using the wind to rotate a blade, the company’s pillars shake back and forth from the vortices created by the movement of air around the structure. Engineers look to avoid these forces when designing buildings and other structures, but the Vortex turbine takes advantage of this phenomenon to oscillate in the wind. Typically, a structure can only be optimized to oscillate at the specific frequencies caused by a certain wind speed, but Vortex says it is using magnets to adjust the turbine on the fly to get the most from whatever the wind speeds happen to be. Once the structure starts vibrating, an alternator in the base of the device then converts the mechanical movement into electricity.

But why bother switching from traditional wind turbines in the first place? Well, Vortex claims that energy produced by its turbines will cost around 40 percent less than energy made from wind turbines that are operating today. A large part of that cost reduction comes from maintenance — since the Vortex doesn’t have moving parts or gears, it should last longer and it won’t require periodic lubrication. The simpler design also means that manufacturing costs are about half that of a traditional wind turbine (those massive blades are expensive). That said, Vortex tells Wired that its bladeless design captures around 30 percent less energy than a regular turbine. The company does note, however, that it’s possible to fit more of the Vortex models in the same area. And, as a bonus, the bladeless turbines are silent.

Vortex is working on a few different sizes; its “Mini,” a 41-foot model, should be ready for commercialization next year, while a larger, industrial model is in the works for 2018. If all goes according to plan, wind farms might look quite a bit different the next time you take a cross-country road trip.

After years of research and a series of unpleasant experiences concerning the current child protection services system, Alec Cope decided to combat the cancerous corruption through information. Freelance writing articles as a form of protest and distributing them throughout his former high-school and local area, Alec struck special chords with whomever he was in contact with.

Alec has been involved in activism such as sit down protests as well as Idle No More gatherings. Being independent for the majority of his time, Alec became a member of the WeAreChange family to assist one of the organizations that inspired him to become active in the first place. With a larger platform and positive support Alec has committed the majority of his time to research, writing, and maintaining social media with the goal to continue expanding the awakening sweeping throughout all levels of society.

Growing up within a rural area in Northern Michigan as well as being a native American descendant, Alec is seeking to expose environmental abuse in his state as well as globally. A high-school dropout, Alec chases his passion for writing and empowering individuals while showing any isolated person that they too can overcome the odds with a community that will support them. Alec lives in the lower peninsula of Michigan near Kalamazoo.
