Look Ma, No Blades!

Have you heard about Vortex Bladeless Ltd.? It’s a Spain (just outside Madrid) based tech company developing a wind power generator without rotating blades. 

STRUCTURE & OPERATION
   ~~~
There is a fixed base and a cylindrical mast that oscillates freely perpendicular to the wind direction, jointed by a carbon rod.

Inner parts never collide with each other, but interact to generate electricity.

ENERGY HARNESS
When the wind passes around a structure, vortexes of pressure are created.

The frequency of vortexes depends on the wind speed, and if the structure has a similar natural resonating frequency, it begins to oscillate and harness their energy.

This phenomenon of aeroelastic resonance is called Vortex Shedding, and happens regularly in nature.

ENERGY CONVERSION
Similar to a traditional alternator, our device gets an interaction between coils and magnetic fields, generating electricity by electromagnetic induction without need for rotation on a shaft nor a gearbox.

The skybrators, as some wits have amusingly dubbed them, stand at a hair over nine feet (2.75 metres) tall.

“Our technology has different characteristics which can help to fill the gaps where traditional windfarms might not be appropriate,” says Yáñez (Inventor, Founder and Co-CEO of Vortex Bladeless). 

These gaps could include urban and residential areas where the impact of a windfarm would be too great, and the space to build one would be too small. It plugs into the same trend for installing small-scale, on-site energy generation, which has helped homes and companies across the country save on their energy bills.

This could be wind power’s answer to the home solar panel, says Yáñez. (source)
