 Singapore : Rain Energy Panels up to 10 times more efficient than traditional hydropower.

Singapore has unveiled a revolutionary technology that converts rainfall directly into electricity — and it’s up to 10 times more efficient than traditional hydropower.

Developed by researchers at the National University of Singapore (NUS), this innovation uses superhydrophobic triboelectric nanogenerators (TENGs) to harvest energy from individual raindrops.

How It Works:

- Raindrops bounce off specially coated surfaces, generating electrical charges through friction.

- The system captures even light drizzle, making it viable in urban environments.

- Unlike dams, it requires no elevation or large-scale water flow — just rain and surface area.

Why It Matters:

- Enables clean energy generation in cities with frequent rainfall.

- Can be installed on rooftops, windows, and public infrastructure.

- Offers a sustainable complement to solar and wind, especially in tropical and monsoon regions.

This breakthrough could redefine how we think about renewable energy in dense urban landscapes.
