A hand-held video game console allowing indefinite gameplay might be a parent’s worst nightmare. But a new version of Game Boy is not just a toy. It’s a powerful proof-of-concept, developed by researchers at Northwestern University and the Delft University of Technology (TU Delft) in the Netherlands, that pushes the boundaries of battery-free computing. Instead of batteries, the special Game Boy harvests energy from the sun — and the user. The researchers say it’s the first battery-free interactive device that “harvests energy from user actions. When you press a button, the device converts that energy into something that powers your gaming.”
