Meet the man who developed a wind turbine capable of providing electricity and drinkable water

For millions of people around the world, including 88 million people in India, access to clean water and energy is a critical issue. Many times, causes like dry weather, tainted groundwater, and resource depletion are blamed for the lack of clean drinking water. A fantastic wind turbine was created in 2020 by Andhra Pradesh, India, electrical engineering student Madhu Vajrakarur. He confronted these issues head-on and came up with a solution that combined the production of safe drinking water with electricity.

The Ground-Breaking Wind Turbine

The invention of Madhu Vajrakarur produces both clean water and power.

This is how it goes:

• Moisture Capture: Similar to how refrigerators use copper pipes to absorb moisture from the air, the wind turbine does the same. The moisture from the wind is directed into the turbine’s structure by a blower at the back of the fan.

• Condensation: The moisture is routed into a cooling compressor once it has entered the turbine, where it condenses into water.

• Filtration: Condensed water is filtered by passing through copper pipes on its way to a three-stage filter. To ensure the purity of the water, this filter uses membrane filters, charcoal filters, and UV filters to remove any dust particles.
• Water Storage: The clean water is stored in a 40-litre external tank and is also accessible through a faucet on the turbine’s frame.

Madhu uses a 30-kilowatt inverter and the electricity produced by the wind to power a variety of home appliances, including fans, lighting, and plug outlets.

While Madhu’s efforts are admirable, it’s critical to address some difficulties and criticisms. The creator of Archimedes Green Energy, which makes rooftop wind turbines, Suryaprakash Gajjala, has expressed doubts about the calibre of Madhu’s work. Gajjala asserts that a turbine producing 30 KW of power for just Rs. 1 lakh could not be of excellent quality or able to resist high air pressures. A dependable wind turbine of this type has a much higher minimum cost.

Childhood fascination sparked Madhu’s interest in building this amazing wind turbine. He created cardboard model replicas for school science shows as early as second grade. He was able to work on this challenging project because to his official training in electrical engineering and practical experience with solar power networks and automatic streetlights. Additionally, at Prime Minister Narendra Modi’s Mann Ki Baat session, he heard about wind turbines that produce water, which gave him inspiration. Madhu was so determined that he watched YouTube videos, drew out the design, located the raw materials, and started the manufacturing process.

Madhu now receives 80 to 100 litres of water each day from his wind turbine, which greatly lowers his electricity costs. His invention has not only made his life better, but it also gives his neighbours and possibly countless others in areas with a lack of water hope.

The wind turbine built by Madhu Vajrakarur is proof of human inventiveness and perseverance. He has tackled two major problems that many people in India and around the world face by combining the production of clean drinking water and power. This invention is a motivating illustration of how people can have a significant influence on their communities and the environment.
