Hamster Power

No, not this kind! Instead:

Hamster Paper Shredder

“An energetic hamster is powering an environmentally-friendly paper shredder by running on his wheel. And he’s certainly got his work cut out for him – as he has to run flat out for 45 minutes to shred one sheet of A4 paper. Happily, he is able to enjoy the fruits of his labor as the paper falls onto the base of his cage, providing fresh bedding for the exhausted pet.”
