Rainforest Connection, currently looking for backing on Kick Starter, developed a way to convert used cell phones into illegal logging detectors. The way it works is a cell phone is connected to a bunch of solar panel, powered on, and then attached high up in a tree. When the phone picks up sounds indicative of a chainsaw it relays it’s location to forest rangers in real time so they can take action immediately to stop illegal logging.
