The system works by placing a cylindrical tube in a water current, which triggers a physical phenomenon known as vortex ...

Add Yahoo as a preferred source to see more of our stories on Google. Researchers from Singapore have developed a clever way to turn raindrops into electricity - enough to power 12 LEDs for 20 seconds ...

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 ...

Often associated with refreshing a sense of being renewed and a peaceful calmness, raindrops may soon become tiny engines of clean energy. Researchers at the Nanjing University of Aeronautics and ...

(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 ...

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 ...

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.

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 ...

As energy use rises and the planet warms, you might have dreamed of an energy source that works 24/7, rain or shine, quietly powering homes, industries and even entire cities without the ups and downs ...

Engineers from MIT have created a unique polymer film that can generate electricity from water vapor. Thin, polymer film can generate electricity from just a small amount of water vapor. The material ...

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 ...
