| Lightdrops Umbrellas Harnesses the Power of Raindrops
This umbrella is ingenious! The Lightdrops umbrella uses the energy of rain to power LEDs. CleanTechnica explains how the umbrella uses the energy in rain:
The polyvinylidene fluoride (PVDF) umbrella features a “collective
membrane” that powers its LED lights with energy from the rain. The PVDF material actually harvests kinetic energy– the heavier the rain, the brighter the umbrella’s LED light becomes.
This cool alternative energy gadget just makes me want to sing:
Raindrops keep fallin’ on my head
But that doesn’t mean my eyes will soon be turnin’ red
Cryin’s not for me
‘Cause I’m never gonna stop the rain by complainin’
Because I’m free
Nothin’s worryin’ me
Nothing’s worrying me because my umbrella’s LEDs are lighting the way!
