Rain could one day become a source of clean electricity, according to a group of scientists in Singapore. Their experiments have been able to generate power from water droplets falling through a tube.

When a solid and a liquid come into contact, charged entities on both sides push one another apart. This phenomenon is known as charge separation, and it creates an electric double layer—a layer each ...

When two materials come into contact, charged entities on their surfaces get a little nudge. This is how rubbing a balloon on the skin creates static electricity. Likewise, water flowing over some ...

Add Yahoo as a preferred source to see more of our stories on Google. Scientists have created a floating droplet electricity generator that turns rainfall into power using water as its own support and ...

At the heart of the technology, a form of hydrovoltaic energy harvesting, is how evaporating water flows through the porous structure of nut shells. As the water moves, it transports electrically ...

Water droplets falling through a tube have generated enough electricity to power 12 LED lights. Such an approach could one day be used in roof-based systems to harvest lots of clean power from rain.

Scientists have successfully generated electricity from water droplets with high efficiency using a method called plug flow, where water columns with air pockets create charge separation. The new ...

Raindrops may seem harmless as they slide down windows or trickle through gutters. But inside each drop lies a powerful secret. When water flows through certain surfaces, it creates electrical charges ...

Water flowing through a thin, polymer-coated tube in short bursts, or plugs, as demonstrated in these illustrations and images, can produce electricity. When two materials come into contact, charged ...
