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 novel hydrovoltaic cell developed by researchers at the Chinese Academy of Sciences (CAS) can continuously generate electricity using little water and no sunlight. This feature could help deploy the ...

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 ...
