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.

Beyond clean power, offshore wind is fixing the ocean. Learn why aquatic wind turbines are doing a lot more than generating ...

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 ...

Tiny drops of water might not seem like powerhouse energy producers, but a new method shows how simple tubes might be able to turn falling rain into an energy source. In tests, the method was able to ...

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 ...

Imagine generating power not from sunlight or wind, but from the simple mixing of fresh and salt water. This is the quiet promise of osmotic energy, a renewable energy source generated where river ...

(Nanowerk Spotlight) The interactions between water and surfaces create small electrical charges – a phenomenon that could power the next generation of wearable technology. Small-scale devices that ...
