Turning Rain into Energy
Engineers in Grenoble, France, are finding energy in the most poetic of places: raindrops. At Research Institute CEA, energy from rain showers is being cultivated transformed into electricity with the help of a plastic called PVDF (polyvinylidene difluoride). PVDF is piezoelectric, which means it produces an electric charge when mechanically deformed.
[Raindrop-powered energy] could be used with solar power to scavenge as much energy from the environment as possible, or to power tiny, wireless sensors designed to monitor environmental conditions.
