Researchers dream up rain-powered devices
“After using computer models to find out just how much energy could be created by rainfall landing on piezoelectric materials, they determined that between 1 nanojoule and 25 microjoules of energy could be generated per drop. Granted, that won’t keep a WoW gamer crankin’ through the eve, but it could be used in everyday sensors that just need a smidgen of power in order to beam back results or data to ground control (or Major Tom).”
