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 surfaces can gain or lose charge. Now, researchers reporting in ACS Central Science have harnessed the phenomenon to generate electricity from rain-like droplets moving through a tube. They demonstrate a new kind of flow that makes enough power to light 12 LEDs.
“Water that falls through a vertical tube generates a substantial amount of electricity by using a specific pattern of water flow: plug flow,” says Siowling Soh, the study’s corresponding author. “This plug flow pattern could allow rain energy to be harvested for generating clean and renewable electricity.”
