Interesting new approach to harnessing the wind:
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.
The solution to the problem lies within the problem itself.
