LightDrops – Rain Powered LED Umbrella
As the days keep getting shorter and weather more moist perhaps the ideal would be an umbrella that lights up.
Better still, how about an umbrella that lights up by the power of rain?
Nah – that could never happen.Â Could it?
The answerÂ is yes; thanks toÂ designer Sang-Kyun Park andÂ LightDrops.
TheÂ umbrella uses the piezoelectric effect of polyvinylidene fluoride (PVDF) to transform falling rain into electricity, which is then used to light LEDs installed on the umbrella’s underside.
So, the heavier the rain fallsÂ the brighter the light shines!
I think the fact that on dark nights it will look like some weird glowing, floating thing is enjoying the rain would be worth the price alone 🙂
