Bladeless Wind Turbine

As urban areas grapple with the pressing need for sustainable energy solutions, traditional wind turbines pose significant challenges with their towering blades and extensive space requirements. These conventional turbines can be noisy, visually intrusive, and even pose risks to local wildlife. Enter the bladeless wind turbine, an innovative answer to the demand for cleaner, quieter, and more aesthetically pleasing energy generation in urban environments.

Bladeless wind turbines offer a revolutionary approach to harnessing wind energy. Unlike its traditional counterpart, this "motionless" turbine eschews blades entirely, instead utilising the principles of vortex-induced vibrations. When wind passes through the cylindrical structure of the bladeless turbine, it creates oscillations. These oscillations are then converted into electrical energy through an alternator. This method of energy conversion not only reduces noise but also eliminates the risks associated with spinning blades, making it safer for both humans and wildlife. Other models use a rotor-stator system with a permanent magnet generator.

These wind harvesting platforms are designed to generate power closer to where it is needed, in facilities such as hospitals, factories, warehouses or apartment buildings. To collect enough energy, at least ten units should be installed on the same flat unobstructed rooftop, on the edge facing the predominant wind direction. They can work independently or in tandem with solar panels, incrementing a robust decentralised renewable power grid.

The adoption of bladeless wind turbines represents a pivotal step towards decentralised energy production. By enabling buildings, parks, and other urban infrastructures to generate their own power, cities can reduce their reliance on centralised power grids, enhancing energy resilience and sustainability. This shift not only mitigates the environmental impact but also promotes energy security and economic savings for urban dwellers.

Design and Analysis of Vortex Bladeless Wind Turbine

sciencedirect.com

Vortex bladeless turbine antiquates the conventional wind turbine and adopts a radically innovative and novel approach to captivate the moving wind energy. This device effectively captures the energy of vorticity, an aerodynamic instability condition. As the wind passes a structure, the flow steers and cyclical patterns of vortices are generated. Once the strength of wind force is suffice, the structure starts vibrating and reaches resonance. Vortex bladeless is a vortex induced vibration resonant power generator. It harnesses wind energy from a phenomenon of vorticity, called vortex shedding effect. Clearly bladeless technology consists of a cylinder fixed vertically on an elastic rod, instead of tower, nacelle and blades which are the crucial parts of a conventional wind turbine. The cylinder oscillates on a specifically mentioned wind range, which then generate electricity through an alternator and a tuning system. In this paper the vortex turbine is designed with certain existing parameters of dimensions in Solidworks and the same is analyzed for different materials and dimensions of mast, which is an important part in the vortex turbine. Also various performance parameters like displacement, frequency etc. are also compared among different models.

Aeromine Technologies, a University of Houston spinoff, has created a rooftop wind device dubbed the AeroMINE. The Houston-based company claims that their unique “motionless” rooftop wind generators operate more or less silently and occupy only 10% of the roof space, producing up to 50% more energy than an array of solar of the same cost. Moreover, they appear legitimate in independent tests.
