Scientists at the National University of Singapore (NUS) have developed a technology that generates electricity from falling raindrops. Using a method called “plug flow,” water droplets pass through tiny tubes to separate electrical charges, significantly improving energy generation efficiency compared to traditional methods.
Laboratory tests show that the system achieves over 10% efficiency with a power density of up to 100 W/m². It can also complement solar panels, especially during rainy conditions when solar output is reduced.
This innovation marks an important step toward sustainable urban energy, enabling power generation in all weather conditions and reducing reliance on conventional energy sources in the future.
