Using Gym Rats' Body Power to Generate Electricity

Carl Bialik from WSJ writes "A Hong Kong health club is hoping that a car battery, some StairMasters and dozens of gym rats can help ease the world's energy problems. It is just one of a wave of projects that are trying to tap the power of the human body, the Wall Street Journal reports. The article explains the impetus behind the project: '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."'"
