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.

Fallstreak holes can technically form naturally, but the most common cause is actually unnatural. Most fallstreak holes form ...

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 ...

Venezuela’s Angel Falls, the world’s tallest waterfall, appears to vanish mid-air as wind, air resistance and evaporation ...

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 ...

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.
