while I love keeping fit, the fact that all my energy practically goes to waste does help in avoiding the gym on occassions that I feel too lazy to move. Think about it, in a world where energy problems are worsening (at least until we conquer some futuristic tech which makes it cheap and plentiful) ; isnt it a criminal waste to exercise your body on a machine when this energy could be used to power something?

You may recall tha cell phone charger that is arriving later this year that is powered from mere motion.

Acting upon this problem, a green gym has opened its doors in Portland which shall attach motors and alternators onto exercise machines so that patrons can help power the 2800 ft gym. While initially about 25% of the gyms power needs will be met in this manner, it is hoped that with improved efficiencies as well as increase in patrons ; the figure shall go up all the way to 100%.
