In fact, Peter’s sister used to complain that Elvis kept her awake at night because he wouldn’t stop playing in his wheel. That got Peter thinking about ways to put Elvis’ energy to good use. So, with a few gears and a turbine, he built a hamster-powered phone charger. And the more Elvis happily played on his wheel, the more talk time Peter got on his Nokia.
