Amrita Vidyalayam Kannur Students Transform Noise Pollution into Electricity with ‘ATL Sonic Power Saver’

November 2020 - A team of students from Amrita Vidyalayam, Kannur—Vrinda Dev, Aadhidev K, and Sneha—has developed an innovative solution to convert noise pollution into electricity. Their project, ATL Sonic Power Saver, secured a spot among India’s top innovations at the ATL Marathon 2019.

Realizing the untapped potential of sound energy, the team designed a device that captures sound waves from noisy environments, such as schools, and converts them into electrical energy using a speaker's reverse process. The generated electricity is stored in batteries, making it a sustainable power source for various devices. The device also integrates AI sensors to manage sound input and intelligently control power distribution, conserving electricity efficiently.

The team conducted extensive testing in different noisy areas to validate the effectiveness of the device. They found that the system could continuously charge batteries, proving especially efficient in loud environments. Encouraged by these results, the students are planning to enhance their prototype with AI-based systems that can collect sound data from classrooms to automate tasks like attendance, power management, and more.

Their ultimate goal is to achieve a ‘Green Campus’ by installing the ATL Sonic Power Saver across their school. Reflecting on their success, the team credited their achievements to teamwork, systematic planning, and guidance from their mentors at Amrita TBI. The students also learned business pitching skills, helping them present their project’s market potential effectively.

This project not only highlights the potential of noise pollution as a renewable energy source but also emphasizes the power of young innovators to tackle environmental challenges.
