The makers say: ‘Vortex Bladeless is a vortex induced vibration resonant wind generator. It harnesses wind energy from a phenomenon of vorticity called Vortex Shedding. Basically, bladeless technology consists of a cylinder fixed vertically with an elastic rod. The cylinder oscillates on a wind range, which then generates electricity through an alternator system.’

New tech developments are happening in the wind power sector, says ZME Science.

Wind power is mostly associated with sweeping white blades, taking advantage of the strong gusts that blow over the land or the sea.

But what if we could forget about the blades and even the wind and instead just have a turbine?

That’s the idea of a group of European companies, who have come up with new ways to expand wind energy without the limitations of a conventional turbine.

Wind has gradually turned into a leading energy source around the globe, with costs dropping every year. But turbines can be problematic: they’re unsuited for some areas, they can harm birds, and they’re not recyclable.

This has led green energy pioneers to start thinking of ways to reinvent wind power – even forgoing the need for the blades in a tower.

In Spain, the small startup Vortex Bladeless has come up with a design that can create energy from winds without the actual blades.

The company claims not to be against traditional windfarms but instead hopes to fill the gaps in locations where traditional wind farms may not be appropriate, such as in urban or residential areas.
