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 ...

Spanish researchers have developed a new system that converts water current vibrations into renewable ...

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 ...

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.

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 ...

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 ...

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 ...

Salt River Project is developing a solar and hydropower project east of Mesa that could power up to 450,000 homes. The project will use a pumped storage hydropower system, releasing water from an ...

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 ...

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 ...
