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

Researchers from Singapore have developed a clever way to turn raindrops into electricity - enough to power 12 LEDs for 20 seconds using nothing more than a small vertical tube and some carefully ...

Picture yourself standing under a torrential downpour. Every single raindrop slamming into your umbrella, your roof, the ...

A new way of generating clean power could run your lights with rain. Hydropower typically relies on the movement of water to create electricity through mechanical energy, such as spinning turbines in ...

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 ...

(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 ...

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.

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 ...
