Device Trains Crows to Find Coins

Josh Klein has an idea that's just so crazy...it might work! Klein has invented a device that autonomously trains crows to deposit coins into a slot in exchange for peanuts. Apparently $215 million in change is lost each year in the US, and crow populations in city areas are growing exponentially. Klein had the thought that instead of culling crows (who tend to adapt to whatever measures are taken to reduce their populations), we should live in harmony with them. Other tasks Klein suggests crows might be useful for include picking up trash and search and rescue.
