In an effort to address our overuse of resources, Finnish designer Tima Naskanen designed the Coin Deposit Lamp. The project is a task light intended for public spaces, such as a library. In order to turn the lamp on, you must deposit a coin into a slot built into the light’s supporting base. When you remove your money after use, the lamp shuts off. This encourages users to turn off the lights when leaving a desk or work area – much like large stores do with their shopping carts.
