Over the years, wind has become a leading source of energy around the globe mainly because of the product costs dropping further every year. However, wind turbines can be problematic. They are not suitable for many regions, can be harmful to birds, and are not recyclable.

Hence, to help eliminate these issues, a small startup Vortex Bladeless from Spain has come up with a wind turbine design that expands the wind energy without the limitations of a conventional turbine. David Yañez, Vortex co-founded, said,

We hope to offer people the possibility of harvesting the wind that passes over their roofs or through gardens and parks with devices that are cheaper to install and easier to maintain than conventional wind turbines. Bladeless turbines can adapt more quickly to changes in wind direction than conventional ones.

The wind turbine design put forth by Vortex is similar to a slender wobbling or oscillating cylinder. Instead of relying on wind to move the blades, this turbine oscillates as the air passes around it and vortices build up behind. This process has been named vortex shedding. The energy from these oscillations is then converted into electricity by the alternator.

The device has very few moving parts and does not require a lot of maintenance, unlike traditional turbines. Moreover, it is easier to install and creates very little noise. Moreover, according to the company, the turbine also has less visual effect and impact on wildlife.

Yañez further said,

Our machine has no gears, brakes, bearings, or shafts. It does not need lubrication and has no parts that can be worn down by friction. Thanks to being very lightweight and having the centre of gravity closer to the ground, anchoring or foundation requirements have been reduced significantly compared to regular turbines, easing installation.

According to the company each turbine could generate as much electricity as 20 square meters of solar panels. This is more than enough electricity to keep the streetlight on and help power the local energy grid.
