Which of the following is not a wind energy application? 

Wind power is a type of energy conversion in which turbines convert wind kinetic energy into mechanical or electrical energy that can then be used to generate electricity. Commercial wind turbines generate electricity by harnessing rotational energy to power a generator.

They are made up of a blade or rotor and a nacelle, which houses a drive train atop a tall tower.

The largest turbines can generate 4.8-9.5 megawatts of electricity, with rotor diameters exceeding 162 metres (531 feet) and towers reaching 240 metres (787 feet). 

Wind energy has a variety of applications. Some of them are as follows:

1. Taking the husk off grains.

2. River-propelled sailboats

3. Transporting vehicles by moving them.

4. Windmills extract groundwater, grind grains, and generate electricity.

A cyclone is a windstorm, not an energy application.
