Hong Kong : Generate Electricity While Exercising

At Hong Kong's California Fitness centers, the new catch phrase might be, no sweat, no light. When club members use certain exercise machines, the energy they generate is turned into stored electricity. To make the fluorescent tubes in the studio's ceiling light up, they have to start pumping.

The consoles of the exercise machines themselves were already powered by human energy. But about 90 percent of the energy produced during workouts was dissipated as heat.

Lucien Gambarota, a Hong Kong-based renewable energy entrepreneur and the inventor of the idea, says an average person can produce 50 watts of electricity per hour.

"Each of these machines, they are equipped with a generator inside. So what we did, we diverted part of the electricity produced by the machine to recharge a battery, he said. "And with what we store in the battery, we have been able to power part of the lighting system."

Gym users are enthusiastic about the new project, which started at the end of February.
