Umbrella Lights The Way

Korean designer Sang-Kyun Park's LightDrops creation lights your way in the rain.
The outside canopy of the umbrella has a conductive membrane called PDVF. As rain comes down, the impact generates electrical energy that powers built-in LEDs on the umbrella.
The heavier the rain, the brighter the light to help you see your way.

What a product!A definite winner on science and technology
