Designer Sang-Kyun Park has designed an LED Umbrella, called LightDrops. This LED umbrella is designed to power by the energy of falling rain drops, it turned the energy of rain to the electricity, and light up the LED. It means that the heavier rain, the LED Umbrella will be very bright.
"As water pours over the surface, potential energy from raindrops slamming onto the conductive membrane called PDVF transforms into electrical energy powering embedded LEDs sending your umbrella ablaze with light. " |
