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 ...

Every day, vast quantities of rain fall across the planet. Until now, all that energy has simply gone to waste. But scientists may have found a clever new way to tap into this overlooked natural ...

A stream of compressed air does not look like a power source. In factories, it usually hisses through pipes, drives tools, then disappears as waste. But under the right conditions, that same airflow ...

AI demand is set to surge 130%, making water security the new power strategy. Learn how water availability now defines energy reliability.

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 ...

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 ...

GILA RIVER INDIAN RESERVATION, Ariz.—About 33 miles south of Phoenix, Interstate 10 bisects a line of solar panels traversing the desert like an iridescent snake. The solar farm’s shape follows the ...
