What if your umbrella could charge your phone? That speculative tech just got a bit closer to reality now that scientists have designed a small, highly efficient electricity generator that can create enough charge with a single droplet of tap, rain, or seawater to power 100 LED light bulbs.
The researchers hope that, alongside solar and wind power, the approach can help tackle the world’s energy crisis. Obviously, generating electricity with water is nothing new. But the study, published on Wednesday in the journal Nature, looked at how a unique connection between the water droplets and the generator interface increased the generator’s overall power.
