#88 – Power Turbine – Madhu Vajrakarur

A young inventor has a simple but innovative solution that can solve the problem of both clean water and electricity.

Madhu Vajrakarur, an electrical engineer from Andhra Pradesh, India, has developed a wind turbine that produces electricity and water for drinking. Yes, you read it right! A wind turbine, which can produce clean drinking water from the moisture in the air.

“Since my childhood, I was unable to get access to clean water and electricity. That time, I decided to find a solution to this problem and started working on such a machine, which will produce electricity as well as clean water.” says Madhu.

The Turbine

The 15-foot tall wind turbine gathers moisture from the atmosphere. Which is then directed through a copper pipe, like the ones used in refrigerators, and finally reaches a three-stage filter.

“The moisture in the wind is directed into the wind turbines frame using a blower placed at the back of the fan. Once this cool air goes into the long frame, the moisture is directed into the cooling compressor which condenses the air into water. The water is then directed through copper pipes into a three-stage filter with membrane filters, carbon filters, and UV filters to collect any dust particles present. Finally, the clean water is accessed through a tap placed on the frame,” says Madhu, adding that the water is stored in an external tank with 40 liters of capacity.

The wind turbine is connected to an inverter, with a 30-kilowatt capacity, and this in turn powers fans, lights, and plug-points in his home.

The wind turbine was made, from plastic pipes, iron rods, and some other elements that were purchased online. 

He started in the first week of October 2020 and finished making the turbine in 15 days. He got help from welders to make the fan, while his friends helped him deploy the structure. It cost him a total of Rs 1 lakh, which was provided by his parents and from his savings.

The inspiration

Building a wind turbine has been Madhu’s dream since his schooling days. As he reached college, he realized that he lacked both the experience and technology to make a real one, but he would make model versions of it using cardboard for science exhibitions organized in school.

“In the second year of college, I learnt how to make solar power grids, and automatic street lights. This gave me the practical knowledge to work with such technology. In October 2020, Prime Minister Narendra Modi in his Mann Ki Baat session spoke about windmills that can generate water and also explained how these wind turbines are deployed in other countries. This inspired me to make one. By watching videos on Youtube I learned more about making a wind turbine that can generate water and electricity. I made drawings of the design, sourced the necessary raw material and started making it,” Madhu says.

Today, the wind turbine is a savior for him and his village. It provides him with 80 to 100 liters of water every day and electricity. His neighbors also benefit from the wind turbine whenever they are short on drinking water.

Madhu is hoping to help others by setting up this wind turbine in water-scarce areas. If you wish to know more, you can reach out to him at madhu.vajrakarur@gmail.com.
