Imagine a gym that ran its lights and TVs off the energy that was generated by all the treadmills and stairmasters being used. That's exactly what some guy in Hong Kong did, hamsterizing his gym to power a few TVs and 60-watt light bulbs with workout-power.

This is just a gimmick to get more customers, since all the electricity generated in a year by these only adds up to $183, whereas the installation cost was $15,000. Still, kinda cool if they knock off some of the membership fees for participants. That would get rid of one of about six excuses we have not to work out.
