In Oregon: A Gym Powered By Exercise

Remember going to the local science museum's elecricity exhibit? You get on a bike hooked up to a generator and pedal away until soon that generator feeds a light bulb, that flickers and burns bright. The Green Microgym in Portland is using the same concept to power the TVs and stereos at the gym. Solar power feeds the lights. Bikes are linked together using a technology called the Human Dynamo.
The Human Dynamo is a bike connected to a battery that stores the energy people create while they pedal. That energy is then converted and appliances plugged into the box feed off its power. The system is particularly effective in group spinning classes, and any other class that involves some sort of wheel.
To save energy the gym also shuts televisions and equipment off when no one's using them.
The Green Microgym's next step in becoming carbon neutral is sending their energy to Portland's power company to create long term energy storage.
