In a breakthrough that could expand the frontiers of clean energy, researchers at the Indian Institute of Technology (IIT) Indore have developed a device capable of generating electricity from the interaction of water and air.
The innovation uses microscopic channels to push water through as it evaporates, triggering ion movement and producing an electric current. The prototype, scientists said, is currently designed for small-scale applications but has the potential to be scaled up.
“This technology demonstrates that everyday natural processes like evaporation can be tapped as a reliable source of power,” an IIT-Indore researcher involved in the project explained.
OTHER IIT INNOVATIONS IN CLEAN ENERGY
- IITs across the country have been working on similar low-carbon technologies:
- IIT Delhi researchers in 2021 designed a device that generates electricity from raindrops, ocean waves, and even household taps, storing the power in batteries.
- IIT Madras developed a microbial fuel cell that uses wastewater to produce electricity, turning sewage into a potential energy resource.
- IIT Jodhpur has been experimenting with perovskite solar cells, which promise higher efficiency and lower costs compared to traditional silicon-based panels.
- IIT Kharagpur researchers recently worked on biodegradable batteries aimed at reducing electronic waste.
Together, these projects reflect India’s growing emphasis on decentralised and sustainable energy research.
The IIT-Indore device is still at a developmental stage. Further research will focus on improving efficiency and adapting it for real-world use, including powering low-energy electronic devices and sensors. Energy experts say the discovery adds to the growing body of work that could help countries like India reduce reliance on fossil fuels while expanding access to clean electricity.
