Sarah writes, “Especially intriguing to those of us from rainy cities is the LightDrops Umbrella by Sang-Kyun Park. This LED-illuminated umbrella turns each raindrop’s energy potential into electricity with a polyvinylidene fluoride (PDVF) conductive membrane. The more it rains, the more light you get. Not exactly dependable, but the conductive membrane is totally fascinating. Imagine what else you could create with this type of conductive membrane! For example, it could be helpful for recreational or permanent tent dwellers.”
