Bladeless Wind Turbines Market Receives Mixed Response

Bladeless wind turbines are not exactly new to the wind power industry, but the relatively recent innovation of a new design of bladeless turbines from Vortex Bladeless, a Spanish company, has the potential to transform the wind energy sector.

The global wind energy market has historically been dominated by bladed turbines, which used the force of the wind to turn blades connected to the generator. While this configuration of wind energy generation is highly efficient and has become a major part of the global energy mix in recent years, the top-heavy design of the conventional turbines leads to several problems. The heavy weight of the turbine at the top of the tall mast can be problematic in extreme weather conditions, and the high number of joints can lead to high maintenance costs.

The Pros and Cons of Bladeless Wind Turbines

In contrast, bladeless wind turbines do not have a specialized turbine at the top; instead, bladeless wind energy generators consist of a mast that oscillates in response to the vortices created by the obstruction to the wind’s flow by the mast. While vortices caused by wind are a problem in architecture, their inevitability has led to researchers coming up with a way to monetize them. Here’s a look at the major highlights of bladeless wind turbines:

• Bladeless wind turbines are less efficient than conventional wind turbines, but multiple bladeless wind turbines can be installed in the same area required for one conventional wind turbine. This increases the overall amount of power generated from the site.

• Bladeless wind turbines are claimed to be much less noisy than conventional wind mills. This will eliminate a major restraint on the usage of wind turbines in residential areas.

• Due to their lack of blades, bladeless wind turbines also pose no threat to birds.
• Due to their lack of moving parts, bladeless wind turbines entail less maintenance costs than conventional wind turbines.
• Despite their several advantages, bladeless wind turbines are a fresh development and are thus relatively untested. This is a major restraint on the global bladeless wind turbines market and more research is needed before the technology can be implemented on a large scale.
