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.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
