Be a human hamster

Remember those cartoons that featured hamsters running on a circular treadmill, generating electricity? Fancy that pipe dream coming true with a gyroscopic generator, allowing you to charge your devices while exercising simultaneously. A rotor in the center of Manual Power keeps on rotating, producing energy that is used to charge a device or stored in a built-in battery. Now you can work out that bod without worrying about your iPod running out of juice. Gizmodo via Treehugger
