As the political and ecological aspects of energy rise in people's consciousness, the search for new and clean ways to generate energy is gaining momentum. A fitness center in Hong Kong has joined the movement with a new idea: the energy generated by the members as they exercise is transformed into electricity to help light the building.

The motto "no pain, no gain" is seemingly out the window at this facility. 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.

Do you think this idea will catch on quickly? Would you like to see this in your local fitness club?
