Adults of average physical fitness can produce between 50 and 150 watts of mechanical power pedaling a bicycle. Why not put that power to work powering electronics, appliances and other machines? You’ll get fit while reducing your dependence of fossil fueled electricity.
Pedal-powered machines are favorite spectacles at fairs and events, churning out smoothies and powering televisions. But pedal-powered blenders are just the beginning, and human-powered technologies date back hundreds of years. Today, the setup usually incorporates a generator and inverter in order to convert your mechanical work into electrical energy. However, this is not always the case. Either way, groups and resources abound to help you construct your own human-powered machines for cheap -- giving you a bit more motivation to move your body.
