Singapore Scientists Generate Power from Raindrops
Researchers in Singapore have discovered a way to generate electricity using rain-like droplets offering a clean and renewable source of energy
Scientists at the National University of Singapore created a tower where water flows through a needle forming droplets that travel down a tube
As the droplets move they rub against the tube surface and create electricity through a process called charge separation much like static from rubbing a balloon
The setup uses a flow pattern called plug flow where short columns of water separated by air boost surface contact and energy transfer
Wires inside the tube and at the bottom collect the electricity converting over 10 percent of the falling water’s energy into usable power
Though slower than real rainfall the method shows promise for rooftops and cities turning everyday rain into a source of clean electricity
This breakthrough could redefine how urban areas harness natural forces offering a small scale alternative to large hydroelectric systems
