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.

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 ...

Researchers in Germany have developed a novel way to generate electricity using nothing more than water and pressure by harnessing the power of friction within the tiniest pores of silicon, the ...

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 ...

Researchers have discovered a new method to generate electricity using small plastic beads. By placing these beads close together and bringing them into contact, they generate more electricity than ...
