Tiny drops, big charge: water movement creates 10x more energy than expected
A new study has found that water moving across surfaces creates ten times more charge than previously thought.
“Most people would observe that rainwater drips down a window or a car windscreen in a haphazard way, but would be unaware that it generates a tiny bit of electrical charge,” said co-author Dr. Sherrell from RMIT’s School of Science in a press release. Although the amount of charge generated during the stick-slip phenomenon seems small (a million times smaller than a static shock you might get from someone jumping next to you on a trampoline), it has implications for fuel-holding systems. “Understanding how and why electric charge is generated during the flow of liquids over surfaces is important as we start to adopt the new renewable flammable fuels required for a transition to net zero,” said co-author Dr. Berry from the University of Melbourne in the press release.
