Electricity From RAIN!

Piezoelectric materials produce an electric charge when under physical stress. Researchers have developed a way to use this effect to harvest energy from falling rain.

Researchers who study energy harvesting see energy all around us – we just need to find a way to capture that energy. One of the latest energy harvesting techniques is converting the mechanical energy from falling raindrops into electricity that can be used to power sensors and other electronics devices.
