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 ...

Tiny drops of water might not seem like powerhouse energy producers, but a new method shows how simple tubes might be able to turn falling rain into an energy source. In tests, the method was able to ...

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 ...

Researchers at MIT have observed “electron whirlpools” for the first time. The bizarre behavior arises when electricity flows as a fluid, which could make for more efficient electronics. Like water, ...

Lower-than-normal rain and snow have reduced Canada’s hydropower production, raising worries in the industry about the effects of climate change. Canadian hydroelectric plants, like the ...
