A new way of generating clean power could run your lights with rain.
Hydropower typically relies on the movement of water to create electricity through mechanical energy, such as spinning turbines in a dam. But a new method, described April 16 in ACS Central Science, skips the mechanics and harnesses tiny bursts of energy sparked when rain plunks into a narrow tube.
“There is a lot of energy in rain,” says Siowling Soh, an engineer at the National University of Singapore. “If we can tap into this vast amount of energy, we can move toward a more sustainable society.”
