Wellness Update: North America: Green gym: Exercise powers machines | Seattle Times Newspaper

Business & Technology | Green gym: Exercise powers machines | Seattle Times Newspaper: "The company revealed its Green System at an International Health, Racquet & Sportsclub Association show in March. Throughout the summer, engineers are working out the kinks in the technology. The system is expected to be on the market by the end of the year.

The equipment harnesses power from exercisers using ellipticals or cycles and turns it into usable power. That means, people work out on Green System equipment and the energy they create goes back to an inverter, a box about the size of a stereo receiver. The inverter converts the power into usable energy, sending it back into a power grid.

SportsArt Fitness claims the Green System can generate up to 2,000 watts of power in an hour. So in that hour, exercisers could create enough energy to run a ceiling fan for 30 hours, a laptop for 40 hours, or a VCR/DVD for 133 hours."
