Korean designer and maker Sang-Kyun Park has come up with the “LightDrops” umbrella that employs a Polyvinylidene Fluoride (PDVF) conductive membrane that transforms the energy from falling raindrops into electrical energy that causes LEDs embedded inside the umbrellas to light up. The heavier the rain, the brighter the lights get, thus illuminating your view. Next up would be to use a windmill on the top of the umbrella to store even more storm energy and build a plug to power your mobile devices from the inclement weather.
