Wind energy to electricity
Technology that conserves natural resources is known as "green technology."
Additionally, it provides us with knowledge and serves as a suitable manual for utilizing natural resources in a more efficient manner.
In this sense, wind is the ultimate natural resource that can be used to generate electricity more effectively. Let's take a quick look at how wind can be converted into electricity in a healthier and more effective manner.
A wind turbine is what?
A wind turbine is nothing more than a sizable machine that uses blades to transform the kinetic energy of the wind into electrical energy. The generator spins as a result of the wind rotating the blades that are arranged around a rotor. The generator produces electricity at the end.

Merits:
One of the most innovative and effective ideas, the wind turbine provides electricity to millions of people and continues to do so.
However, it does have certain drawbacks.
1) A lot of birds are constantly dying after being struck by the massive wind turbine blades, which simply obstruct some of their paths.
2) A lot of noise is made by the turbine as it rotates.
3) A significant quantity of space is needed for wind turbine installation.
Creation of wind turbines without blades
(David Yael) and his team created vortex bladeless wind turbines to eliminate the issues associated with bladed wind turbines. Turbines of this kind don't have blades.
How does it function?
The mast, alternator, anchor, and generator are the main components that go into making the vortex bladeless operate.
*Building: The alternator is encircled by the mast and connected to the anchor, rectifier, and then the generator.
*Mechanism:
A vortex is created as soon as the wind strikes the mast (spinning motion of the wind). The mast then begins to move as the wind blows against it. As soon as the vortex wind makes contact with the mast (assuming the wind's frequency is equal to the natural frequency of the mast), resonance takes place, causing the mast to oscillate and make contact with the alternator, which vibrates. This kind of vibration is known as vortex induced vibration.
That vibration produces kinetic energy, which the generator then transforms into electrical energy.
Advantages over a wind turbine with blades
1) If there is an issue with the device, it is simple to fix.
2) Its mechanism is not as sophisticated as a wind turbine with blades, making any issues simple to fix.
3) Does not harm any living things in any way.
The Vortex design has a lot of benefits. To begin with, it is less expensive to produce than conventional pinwheel turbines. Given that there is no friction between moving elements in the design, it is also less expensive to repair. Birds may fly about them without worrying about getting sucked in or being hacked to bits by blades since they are absolutely silent.
As is customary anytime a new alternative energy source is proposed, some people are doubtful about the effectiveness of such a design. However, the Vortex's creators assert that their turbine has already undergone prototype testing utilising the Vortex Atlantis, a 100 W variant, and has been computationally modelled and tested in a wind tunnel.
