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 ...

Chinese scientists have recently unveiled a floating hydrovoltaic generator that converts the energy of falling raindrops directly into electricity while resting on water surfaces. Designed at the ...

The conventional droplet electricity generator (C-DEG) uses a metal bottom electrode and a rigid substrate, and is generally employed on land. In contrast, the new water-integrated floating droplet ...

What if solving three of the world’s most pressing challenges, water scarcity, energy demand, and environmental sustainability, could be achieved with a single, innovative system? Imagine a technology ...

(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 ...

A Japanese water plant is harnessing the natural process of osmosis to generate renewable energy that could one day become a common power source.

Researchers at EPFL have developed a nanoscale hydrovoltaic device that continuously generates electricity from evaporating saltwater, enhanced by heat and sunlight. The three-layer system separates ...
