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.
