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.

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 ...

Water has long been a source of renewable power. More than 2,000 years ago the Chinese used water wheels to grind grain and pound ore. In the 1700s water wheels kickstarted the Industrial Revolution ...

Professor and Students at the Indian Institute of Technology Indore (IIT Indore) have developed a unique device that produces electricity using nothing but just water and air--without the need for ...

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 ...

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 ...
