These bladeless wind turbines create electricity without spinning
The turbines we currently use for wind power are incredibly advanced pieces of technology. Everything inside of them –from the shape of their airfoils to the generators they spin– has been painstakingly engineered for maximum efficiency. They’re a very mature technology, but that’s not to say an alternative concept might not be an improvement.
Case in point: these incredible tube-like wind turbines from Spanish startup Vortex Bladeless. Through a clever manipulation of physics, the company’s turbines are able to generate electricity without the help of any large, spinning blades. It sounds crazy, but it’s totally legit — Vortex has been developing the turbines for the past few years, and even went so far as to build its own wind tunnel to prove the technology works.
