IIT Indore Develops Self-Charging Power Device That Generates Electricity from Water and Air
Scientists at IIT Indore have developed a groundbreaking device that can generate electricity using only water and the process of evaporation. This innovation does not require solar power, batteries, or any complex machinery.
A Unique Invention – Works Day and Night Without Sunlight
Unlike traditional solar panels, this device functions continuously, regardless of sunlight. It utilizes only water and natural evaporation to produce power, making it an ideal solution for areas with limited access to electricity.
How It Works
The core of this device is a special membrane made from graphene oxide and zinc-imidazole. When partially submerged in water, the membrane allows water to travel upwards through tiny channels and evaporate. During this process, positive and negative ions are separated, which generates a stable electric voltage.
A single small membrane (3×2 cm²) can produce up to 0.75 volts of electricity. Multiple membranes can be connected to increase the power output.
Key Features
- Works with clean, salty, or dirty water
- Operates for months with stable performance
- No sunlight or batteries needed
- Ideal for off-grid or emergency power needs
Potential Applications
- Powering environmental sensors in forests and agricultural fields
- Emergency lighting during blackouts
- Running low-power medical devices in remote clinics
This innovation from IIT Indore could pave the way for decentralized, eco-friendly, and self-sustaining energy solutions, especially in remote or underserved regions.
