The LightDrops Rain-Powered Electric Umbrella
The LightDrops umbrella will offer you exactly what its name suggests. Once drops of rains fall on it, it converts it into light. This umbrella has PDVF, a conductive membrane that converts the falling water’s kinetic energy into electricity in small amounts. This electricity will basically be enough to provide power to the LEDs present inside the canopy of the umbrella. And, once the lights appear it certainly looks beautiful.
