Green gym generates electricity from bikers


With row after row of exercise machines, most gyms burn far more electrical power than calories. But by equipping stationary bikes and elliptical machines with generators, a San Diego gym has become as healthy for the Earth as it is for its patrons. The gym, named the Greenasium, uses a special bike called the visCycle. The visCycle generates enough electricity to offset the box fan that the Greenasium uses to cool down the room. That fan constitutes most of the gym's electricity use, as there is no air conditioning. When more than one person uses a visCycle or similarly equipped elliptical, the cardio machines put out enough power to offset the music, computer and lights as well.
