IIT Indore researchers create small-scale electricity generator using water and air

IIT Indore researchers have unveiled a new device that can generate electricity by harnessing the natural interaction between water and air, marking a potential breakthrough in clean energy technology.

The prototype works by channeling water through microscopic pathways; as the water evaporates, it creates ion movement, producing a measurable electric current.

Scientists involved in the project noted that while the device is currently suited for small-scale applications, it could be expanded for broader energy use.

“This technology demonstrates that everyday natural processes like evaporation can be tapped as a reliable source of power,” said a researcher from IIT Indore.

This innovation joins a series of energy-focused projects across Indian Institutes of Technology.

In 2021, IIT Delhi developed a device that converts energy from raindrops, ocean waves, and household taps into electricity, storing it in batteries.

IIT Madras has created microbial fuel cells that produce electricity from wastewater, while IIT Jodhpur is experimenting with cost-effective, high-efficiency perovskite solar cells.

IIT Kharagpur has been working on biodegradable batteries to cut electronic waste.

Experts say the IIT-Indore device, still in its developmental phase, could power low-energy electronics and sensors.

The research contributes to India’s growing push for sustainable, decentralized energy solutions and could help reduce reliance on fossil fuels while expanding access to clean electricity.
