University of Waterloo engineering researchers in Canada have developed a way to capture electricity from water evaporating on walnut shells, opening up off-grid possibilities for small electronic ...

Scientists have showcased that cotton can work as a power source and harvest electricity from humidity. Scientists have now ...

(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 ...

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 ...

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 ...

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 ...

Scientists have developed a new technique that doubles the amount of hydrogen produced when splitting water molecules with ...

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 ...
