Please Don’t Say This Idea Is All Wet

Ongoing research into harnessing the power of droplets could change people’s perspectives about rainy days.

Even though it really sort of is.

Perhaps we should explain: A research team led by scientists from the City University of Hong Kong (CityU) is developing a “droplet-based electricity generator with high instantaneous power density.” That means they have found a way to convert the energy of droplets, such as rain, into electricity.

“This groundbreaking achievement can help to advance scientific research into water energy generation and tackle the energy crisis,” CityU declared.

To harvest kinetic energy, the technology might someday be installed on the hull surfaces of boats, or even on umbrellas or inside water bottles. The Hong Kong team has been able to light 100 small LED bulbs with a single drop of water. So, for now, the forecast calls for more R&D.
