How to generate electric power by human body? The world wide chain California Fitness has an idea. The human power project at California Fitness was set in motion by Doug Woodring, a 41-year-old extreme-sports fanatic and renewable-energy entrepreneur, who pitched the experiment to the gym's management last May. "I've trained my whole life, and many megawatts have been wasted," says Mr. Woodring, who has worked out at the Hong Kong gym for years. "I wanted to do something with all that sweat.
His partner Mr. Gambarota rewired the generators in 13 machines on the gym's main floor to capture the excess energy, running wires underneath the carpets to a car battery that could store the power.
